Dramatic Growth of Open Access March 2018

As usual open access is showing strong growth in many directions; more open access archives, documents, journals, articles, and books. This quarter focuses on the large number of indicators of growth beyond the usual background growth of scholarly journals and articles of 3 – 3.5% per year. Newcomer bioRxiv, with 21% growth this quarter (equivalent to 84% annual growth) is far above this background growth. This quarter, DOAJ added a net total of 378 journals, or more than 4 journals per day, for a total of 11,105 journals. The number of journals searchable at the article level has increased by 236 for a total of 8,045 journals. The number of articles searchable at the article level is just under 3 million.  The number of documents searchable through BASE grew by 3.5 million for a total of just under 24 million (about 60% of these, over 14 million, are open access). BASE added 121 content providers for a total of over 600 content providers. The percentage of PubMed records for a search for “cancer” that retrieve full-text is 27% overall, with a high of 45% for records published in the last 5 years. The percentage of full-text retrieval is rising at a steady rate.

The overall growth rate for scholarly articles and journals has been fairly steady over the past few centuries, in the range of 3 – 3.5% growth annually (Price, 1963; Mabe & Amin, 2001). As noted in the following chart, in the past quarter alone there have been 43 indicators of growth above that level, at least 1% in the quarter (equivalent of 4% annually).

Dramatic Growth of Open Access December 31, 2017

Highlights

As usual the open access movement has much to celebrate as 2017 draws to a close, and the whole world has much to look forward to from open access in 2018. As of today there are 4.6 million articles in PubMedCentral, thanks in large measure to constantly increasing participation by scholarly journals; sometime in 2018 this is likely to exceed 5 million. DOAJ added a net 1,272 journals (3.5 / day) and showed even stronger growth in article searchability; a DOAJ milestone of 3 million searchable articles in likely to come in 2018. The Directory of Open Access Books nearly doubled in size and now has more than 10,000 books from 247 publishers. Bielefeld Academic Search Engine, the best surrogate for overall growth, continues to amaze with over 120 million documents, growth of 17.3 million in 2017, a 17% growth rate on a very substantial base; a 20% growth in content providers is an indication of the overall growth of the repository movement. arXiv’s growth rate was 10% while newcomer arXiv clones socRxiv grew by 187% and bioRxiv by 151%. REPEC grew by 13%, SCOAP3 by 32%. Internet Archive grew by 31 billion web pages, 4 million texts, 2.4 million images, 800,000 movies, and 600,000 audio recordings. Following are selected details indicating the content numbers at the end of 2017, 2017 growth by number, percentage, and where warranted, by day.

    Dramatic Growth of Open Access June 30, 2017


    Correction: DOAJ will soon surpass 2.5 million articles, not a quarter of a billion as originally reported. 

    Highlights

    Open access continues to demonstrate robust growth on a global scale, in terms of works that are made available open access, ongoing growth in infrastructure (new repositories, journals, book publishers), strong growth for new initiatives such as SocArxiv, BioRxiv, the Directory of Open Access Books, SCOAP3, as well as ongoing strong growth in established services such as BASE, PubMed / PubMedCentral, Internet Archive (check out the new Collections including a Trump archive and FactChecker), DOAJ (almost 2.5 million articles searchable at the article level), RePEC and arXiv. Ongoing growth in infrastructure and OA policy give every reason to expect this growth to be ongoing.

    Open Data Version

    Morrison, Heather, 2014, “Dramatic Growth of Open Access”, hdl:10864/10660, Scholars Portal Dataverse, V17,

    Details

    This edition of the Dramatic Growth of Open Access highlights two of the new kids on the OA block – SocArxiv and BioRxiv, modeled on early OA success story arXiv, topping the quarterly growth by percentage with percentage growth of about 30% each! SocArxiv now has 1,200 documents and BioRxiv 12,800.

    Similarly, a relative newcomer, the Directory of Open Access Books, is in both first and second place for annual growth by percentage with 68% growth for OA books and 40% of OA publishers in the past year for a total of 8,172 open access books and 217 OA book publishers.

    SCOAP3, a global initiative to transform high-energy physics publishing to open access, is showing remarkable growth, 39% in the last year and 8% in the last quarter for a total of 15,790 articles funded.

    To celebrate the growth of all OA services two pictures are presented of the growth of the largest collective OA search engine that I am aware of. Together, the 5,000 content providers who contribute metadata to the Bielefeld Academic Search Engine (BASE) have made available over 112 million documents. Around 60% of these are open access, so the number of OA documents in the world can be said to be somewhere about 67 million. BASE also posts their own online statistics table and chart – check it out here.

    I wish I had the time to applaud and celebrate the growth of each and every OA service, but with 5,000 services contributing to BASE (and others that don’t), if I worked on this 365 days a year I would have to cover 14 initiatives every day. So please feel free to help out by applauding and celebrating the services most relevant to you – the journals in your discipline, your institutional repository, the services you find most helpful to search.

    Below you will find tables listing the top services by quarterly (5% or more) and annual growth (10% or more). For the full numbers download the open data version (link above). As usual Internet Archive is well represented, with 5 items in the list of the top 13 services by quarterly growth and the top 18 services by annual growth. Internet Archive also offers 2 intriguing new services under Collections – a Trump Archive with over a thousand videos and a Fact Checker collection with over 400 items, available at https://archive.org/details/tvhttps://archive.org/details/tv

    Of course PubMed and PubMedCentral are up there in the growth charts, in this quarter for total number of items (5% quarterly growth) as well as what looks (to me) like hesitant new steps by a substantial number of journals, with a 26% increase in the number of contributing journals that provide some OA and a 14% increase in the number of journals that provide OA to selected articles. The number of journals providing immediate free access and/or all articles open access continues to increase, so this is clearly growth, not backsliding.

    DOAJ is included in the top growth services with 14% growth in the number of articles searchable at article level. DOAJ now has over 2.49 million articles searchable at the article level and should soon surpass 2.5 million articles.

    arXiv and RePEC are on the list for strong growth in articles, and ROARMAP for growth in OA policies.

     Highlights

    Arguably the best indicator of the global collaborative growth of open access, whether through archives or publications, is the ongoing impressive growth of what we can access through the Bielefeld Academic Search Engine, which surpassed two major milestones in 2016: over 100 million documents (about 60% open access) and 5,000 content providers. The growth rates (22% for documents, 27% for content providers) are particularly impressive given the high pre-existing content rate. This is amazing success not just for BASE, but for all of us. If you’ve published a thesis through an institutional repository that allows for metadata harvesting, or published an article in a journal that contributes article-level data for metadata harvesting, your contribution is reflected here. This is a meta-level indicator of our global success.

    I’ve added a new metric for medical open access, a keyword search of PubMed for “cancer” for articles with no date limit, last 5 years, last 2 years, and last year, further limited to free fulltext to determine the percentage of items for which fulltext is available. This ranges from 26% overall (no date limit), to 40 – 44% for items published in the last 2 – 5 years, to 32% for articles published in the last year.

    Also added this quarter: OECD iLibrary – with more than 11,000 free books, this one publisher’s OA collection is nearly double the size of the 167 publishers included in the impressivley growing Directory of Open Access Books! arXiv, in addition to an over 10% growth rate last year, inspired the recent development of two similar services, socArXiv and bioRxiv, newly added to facilitate future growth tracking. The DOAJ get-tough inclusion policy and March 2016 major weeding means the DOAJ count for titles, countries and journals searchable at the article level are all down from last year, while articles searchable at the article level through DOAJ continued to show robust growth of 13%. DOAJ’s quarterly growth is back to an impressive rate of just under 3 titles per day. RePEC surpassed a milestone of 2 million downloadable items this year, while Internet Archive surpassed 3 milestones: there are now more than 3 million video and audio recordings, and more than 11 million texts (the number of IA web pages archived is way down, by the billions – such a difference it strikes me as likely due to a glitch in counting, whether before or after). Recently Open Journal Systems announced that OJS is now used by more than 10,000 active journals which <>.

    Kudos and thanks to everyone in the open access movement – every researcher, author, editor, publisher, archive manager, librarian, policy-maker, and activist who is making open access happen. What of 2017? My advice: let’s remember the beautiful vision of the potential unprecedented public good of open access – forged not at a time of peace and certainty, but rather within months of the trauma of 9/11 – repeated below – and keep on making it happen.

    BOAI vision:

    An old tradition and a new technology have converged to make possible an unprecedented public good. The old tradition is the willingness of scientists and scholars to publish the fruits of their research in scholarly journals without payment, for the sake of inquiry and knowledge. The new technology is the internet. The public good they make possible is the world-wide electronic distribution of the peer-reviewed journal literature and completely free and unrestricted access to it by all scientists, scholars, teachers, students, and other curious minds. Removing access barriers to this literature will accelerate research, enrich education, share the learning of the rich with the poor and the poor with the rich, make this literature as useful as it can be, and lay the foundation for uniting humanity in a common intellectual conversation and quest for knowledge.

    Selected numbers and growth by service:

    Directory of Open Access Journals 

    Highlights: in March 2016 DOAJ removed more than 3,000 journals, reflecting a new get-tough inclusion policy. All journals that had not gone through DOAJ’s new application process were removed. As a result, in spite of robust quarter since the removal process, most of DOAJ’s key data are lower at the end of 2016 than at 2015, with the exception of number of articles searchable through DOAJ which grew by 13%.

          Highlights

          There is plenty to celebrate for this year’s Open Access Week October 24 – 31 everywhere! 



          As of Oct. 6, 2016, a Bielefeld Academic Search Engine (BASE) search includes over 100 million documents! Globally the collections of open access archives are now collectively an order of magnitude larger than the 10 million articles and books claimed by Elsevier for Science Direct. Congratulations to BASE and everyone in the repositories movement that is making this happen!

          In spite of a vigorous weeding process, new get-tough inclusion policy and negative growth in the past year in journal numbers, the Directory of Open Access Journals showed an amazing 11% growth in the past year in articles searchable at the article level – about half a million more articles today than a year ago. This past quarter DOAJ showed a healthy growth rate of 135 titles or added 1.5 titles per day.

          For every journal added by DOAJ in the past quarter, another repository was added to the vetted OpenDOAR collection of repositories.

          The Internet Archive now has more than 3 million audio recordings.

          The Directory of Open Access Books added over 2 thousand titles in the past year for a current total of over 5,000 titles (60% annual growth rate) from 161 publishers (41% annual growth rate in publishers).

          The number of journals actively contributing to PubMedCentral continues to show strong growth in every measure: there are 212 more journal active participants in PMC today than a year ago, a 10% growth rate; 170 more journals provide immediate free access, an 11% growth rate; 113 more journals provide all articles as open access, a 9% growth rate; and the number of journals with some articles open access increased by 123, a 31% growth rate.

          Dramatic Growth of Open Access March 31, 2016

          Highlights

          There are now 150 publishers of peer-reviewed open access books listed in the Directory of Open Access Books, publishing more than 4,400 open access books. 620 books were published in this quarter alone, a 16% increase in just this quarter. The Directory of Open Access Journals has been adding titles at a net rate of 6 titles per day, 540 journals added this quarter for a total of over 11,000 journals. This is the highest DOAJ growth rate since this series started!

          Bielefeld Academic Search Engine repositories collectively added more than 4.7 million documents this quarter for a total of just under 89 million documents.

          SCOAP3 nearly doubled in size this past year (87% annual growth) for a total of 4,690 documents. arXiv grew by over 107,000 documents to over 1.1 million documents during the same time frame. 

          Internet Archive is likely to be featured in the next issue as it is currently edging towards a milestone of 10 million free texts.

          The number of journals actively participating in PubMedCentral, making all content immediately freely accessible, and making all content open access, continues to grow. Meanwhile at PubMed a transition in indexing practice (from manual to automatic) means that a search for NIH-funded articles in the last 90 days significantly underreports results (1,402 NIH funded articles in the past 90 days compared with a range of 7,846 – 19,790 with a 90-day search limit for NIH funded article since 2008). Without the indexing, it is not possible to determine the percentage of full text. Here’s hoping the automated indexing process results in a catch-up soon; it doesn’t matter very much if the statistics for this series fall a bit behind, but people rely on this indexing to search for medical information.

          The Electronic Journals Library added 3,612 journals that can be read free-of-charge in the past year, for a total of 52,000 journals, a 7% growth rate.

          Dramatic Growth of Open Access December 2015

          Highlights

          After a year or so of slower growth at DOAJ to accommodate back-end technical work and a new get-tough policy on journal inclusion, robust DOAJ growth is back on track. In the last quarter of 2015, DOAJ added a total of 384 titles or more than 4 titles per day for a year-end total of 10,963 journals. The number of articles searchable at the article level grew by over 300,000 in 2015 for a year-end total of over 2.1 million. The Bielefeld Academic Search Engine figures demonstrate the overall growth of (mostly) open access repositories, adding more than 15 million documents in 2015 for a total of more than 84 million and adding 671 content providers for a total of just under 4 thousand content providers. Both document growth and content provider growth at BASE reflects greater than 20% growth for 2015, a particularly impressive number given that percentage growth tends to favour newer, smaller initiatives such as the SCOAP3 repository which had the highest growth by percentage in 2015, more than doubling to over 8,000 articles in 2015. Although not all the documents available via a BASE search are open access, the more than 3.7 million items now available for free from PubMedCentral alone is just one indication of robust growth in open access repositories. The Internet Archive now has more than 8.8 million texts. Perhaps even more impressive is that over 8 million of the texts made available by the Internet Archive and Open Library are fully accessible and in the public domain! Following are a few charts to illustrate the ongoing amazing growth of open access. To sum up, only one resolution is recommended for all the people behind the thousands of open access journals, repositories and other services for 2016: keep up the good work!

          Open data is available through the Dramatic Growth of Open Access dataverse. For previous posts see the Dramatic Growth of Open Access series.

          Dramatic Growth of Open Access June 30, 2015

          This issue of the Dramatic Growth of Open Access highlights and celebrates samples of the many small milestones illustrating the slow and steady increase in open access (dramatic does not necessarily mean fast!).

          There are now more than 2,000 journals actively participating in PubMedCentral. Over the past year, this number grew by 178 – that’s close to one more new entire journal actively contributing content to PMC every business day.

          PMC now has over 3.5 million items. This means that about 15% of all the 24 million items cited in PMC (regardless of date of publication) have free fulltext available linked from PubMed.

          In the last 7 years, the number of NIH funded articles indexed in PubMed (again regardless of date of publication) available for free grew from 86 thousand to over 600 thousand or from 34% to 71%.
           

           
          Other small milestones: there are now over 100 publishers of open access scholarly books listed in the Directory of Open Access Books; the Social Sciences Research Network now includes over half a million full text papers; the Registry of Open Access Repositories now lists over 4,000 repositories; and the Bielefeld Academic Search Engine now has more than 75 million documents. Congratulations and thanks to everyone who is doing all the behind-the-scenes work that results in this dramatic increase in access to our knowledge (whether your initiative is highlighted this particular issue or not). To download the data go to the DGOA dataverse.

          Selected data

          Directory of Open Access Journals is going through a clean-up project; the number of journals listed decreased by 45 this semester (over the past year growth of 471 titles). Journals and articles searchable by article both grew this quarter.

          The Directory of Open Access Books lists 3,197 titles from 107 publishers; over 50% annual growth for both numbers.

          The Electronic Journals Library added 801 journals that can be read free-of-charge for a total approaching 50,000 titles.

          The Bielefeld Academic Search Engine added more than 3.6 million documents for a total over over 75 million documents.

          This quarter PubMedCentral added the following (journal rather than article data). A key point is that increases are happening consistently in every category.

          • 33 journals actively participating in PMC (total over 2,000)
          • 23 journals with immediate free access (total 1,468)
          • 24 journals with all articles open access (total 1,260)
          • 46 journals that deposit ALL content in PMC (total 1,683)
          • 9 more journals that deposit NIH-funded content only (total 310)
          • 268 journals that deposit selected content in PMC (total 3,246)

          arXiv added over 25,000 publications and now has more than a million. 

          RePEC added over 64 thousand downloadable items for a total of over 1.6 million. The Logec service has lots of great stats (downloads, content by type and by date); highly recommended for anyone looking for more detail in this area.

          Social Sciences Research Network added close to 13 thousand fulltextpapers for a total of more than half a million.

          Internet Archive added:

          • 100,000 movies for a total of over 2 million
          • 4,000 concerts for a total of 153 thousand
          • 100,000 audio recordings for a total of over 2.5 million
          • 300,000 texts for a total of over 8 millio

          Dramatic Growth of Open Access 2015 first quarter

          Data for the first quarter of 2014 (the 11th year of publication of this series) are now available in the dataverse. Error note re Dec. 31, 2014 version: the number for Electronic Journals Library was copied incorrectly (total journals mistook for free full-text journals). Noted as an error in the current version, will result in under-reporting of growth of this initiative in the near future.

          Highlights

          OpenDOAR added 129 repositories for a total of 2,857. The Bielefeld Academic Search Engine added close to 3 million documents for a total of over 71 million documents. Another 7,690 authors joined the Social Sciences Research Network for a total of over 275,000 authors.

          Internet Archive added 1.7 million texts for 7.8 million.

          The Directory of Open Access Journals, in spite of vigorous weeding and re-organizing over the past year or so, is back to showing consistent strong growth, adding 254 titles this quarter for slightly under 3 titles per day. Over the past year, the growth in articles that can be retrieved through a DOAJ article-level search grew by over a quarter of a million articles for a total of over 1.8 million articles! 20 more publishers joined the Directory of Open Access Books – as of today, DOAB includes 100 publishers.  Highwire Press added 9 completely free sites this quarter. The number of journals with immediate free access in PubMedCentral increased by 43 to a total of 1,443.

          Congratulations and thanks to all of the people and organizations working hard to make open access happen. This is a major step for every author signing up for a repository, every journal moving to immediate free. I wish I had the time to thank and celebrate each of your accomplishments individually.

          2014 Dramatic Growth of Open Access: 30 indicators of growth beyond the ordinary

          There has been a remarkably constant growth rate of scholarly journals since the 1600’s (De Solla Price, 1963, p. 17). Mabe (2003) calculates the average annual scholarly journal growth rate at 3.46% per year from the 1600’s to the present day, with an increase to 4.35% from 1946 to 1976 and subsequent fall to 3.26% after 1976.
          This issue of the Dramatic Growth of Open Access highlights 30 indicators of open access growth that are beyond this background growth of scholarly works – in many cases far beyond, with a range of percentage growth from 5 – 89%. In some cases, high percentage growth reflects early start-ups (low starting figures), but in other cases there are very high growth rates on resources that were very, very large to begin with (these are the highlighted numbers below). Note that some numbers are rounded for ease of understanding; if precise numbers are required, please download the full dataset from the DGOA dataverse.

          A special congratulations is in order to arXiv for recently surpassing the milestone of over 1 million documents. Note that these 30 indicators likely underestimate the growth of open access beyond the ordinary by a large factor, as this series focuses on just a few indicators of macro level growth of open access. To continue the momentum in 2015 open access advocates are encouraged to remember the vision of open access as unprecedented public good and not get caught up in the minutiae of implementation. Although the focus of this series is the numbers, a special mention to an exceptional open access policy recently announced by India’s departments of Biotechnology and Science and Technology which represents a new model OA policy for the whole world.

          Open access indicators with percentage growth above the 3.5% background growth of scholarly works in 2014

          • 89% growth – over 38,000 more journals that are free-to-read: the libraries collaborating on the Electronic Journals Library service added 38,865 journals that are free-to-read in 2014 for a total of 82,363 journals that can be read free of charge. This figure encompasses not only the fully open access, peer-reviewed journals included in DOAJ, but also the many journals that are free to read after an embargo period or that are of interest in an academic context without necessarily being peer reviewed. 
          • the Directory of Open Access Books was hopping in 2014, adding:
            •  863 books for a total of 2,482 (53% growth) 
            • 25 publishers for a total of 79 (46% growth).
          • the Internet Archive added:

          A call to remember the vision of open access in 2015

          As open access moves further and further from idea to reality, it’s all too easy to get caught up in the minutiae of implementation: the procedures of developing open access archives, journals, books and other works and the development of the technology and services to make it happen, and to make the works attractive to use. In the process of developing OA initiatives, it may well be useful to develop and implement a variety of standards, new metrics and technical procedures. But in the process let’s not confuse the means with the ends – let’s keep our rationality rational (Morrison, 2012) and focused on the goals that we really want to achieve.

          To further grow the momentum in 2015, let’s remember the great vision of open access, as expressed in the first paragraph of the 2002 Budapest Open Access Initiative:

          An old tradition and a new technology have converged to make possible an unprecedented public good. The old tradition is the willingness of scientists and scholars to publish the fruits of their research in scholarly journals without payment, for the sake of inquiry and knowledge. The new technology is the internet. The public good they make possible is the world-wide electronic distribution of the peer-reviewed journal literature and completely free and unrestricted access to it by all scientists, scholars, teachers, students, and other curious minds. Removing access barriers to this literature will accelerate research, enrich education, share the learning of the rich with the poor and the poor with the rich, make this literature as useful as it can be, and lay the foundation for uniting humanity in a common intellectual conversation and quest for knowledge.

          Special acknowledgement of a new leading-edge open access policy

          The recently announced new open access policy of two of India’s science departments represents the best of funding agency open access policy to date and includes important advances. There is a focus on green or open access archives and a call to develop the institutional repository system to implement the policy. This will ensure that the results of research funded by India remains open access and remains available to Indians – there is no substitute in OA policy for ensuring local control. The maximum embargoes are six months in the sciences and one year in the humanities and social sciences. The major advance is inclusion of the San Francisco Declaration on Research Assessment instructing evaluators not to consider impact factor or other metrics in assessing the work of researchers, but rather focus on the quality of the work per se. This is an absolutely critical step in addressing the systemic dysfunction in the scholarly communication system I have described elsewhere (Morrison, 2012), facilitating a shift to rational rationality, a system that is free to prioritize the advancement of scholarly knowledge, the knowledge commons, rather than the imperfect measures people have devised as heuristic devices.
