Abstract: In this article I call for more recognition of and scholarly engagement with public, volunteer digital humanities projects, using the example of LibriVox.org to consider what public, sustainable, digital humanities work can look like beyond the contexts of institutional sponsorship. Thousands of volunteers are using LibriVox to collaboratively produce free audiobook versions of texts in the US public domain. The work of finding, selecting, and preparing texts to be digitized and published in audio form is complex and slow, and not all of this labor is ultimately visible, valued, or rewarded. Drawing on an ethnographic study of 12 years of archived discourse and documentation, I interrogate digital traces of the processes by which several LibriVox versions of Anne of Green Gables have come into being, watching for ways in which policies and infrastructure have been influenced by variously visible and invisible forms of work. Making visible the intricate, unique, archived experiences of the crowdsourcing community of LibriVox volunteers and their tools adds to still-emerging discussions about how to value extra-institutional, public, distributed digital humanities work.
