The aim of the bibliography is to help share resources amongst scholars interested in online and digital documentary, and it arose from a discussion amongst some of us in 2012 in Canberra.
Anyone can view the bibliography but to contribute you need to join Zotero (free) and then request an invitation to join the bibliography group from within Zotero. Once a subscribed member you are able to add and edit citations. Please note, if you can add a citation you can also delete one, so use with caution! To see the bibliography you just need the link.
Why Zotero? I already use it and decided I didn't want to run Zotero, and Mendeley is now part of the darker side. I also am very supportive of the work that the Roy Rosenzweig Center for History and New Media does (even if they can't spell centre).
The material might be moved elsewhere one day, for instance onto a web site, but Zotero makes it easy for those interested to access the bibliography and use it personally, and contribute to it if they wish. So apart from just having these references available, it also makes them highly usable.
Zotero treats a group as a 'box' and within that you have folders to sort references. The one reference can be dragged into multiple folders if you like. Citations can be to anything you'd expect, web sites, blog posts, journal articles, book chapters, books, films, and so on. You can add notes and tags to individual entries, though I think tags won't amount to much but notes would be useful - keep in mind though that all is public! You can also attach pdfs where appropriate to entries.
Be inclusive and generous in what you include. If it appears marginal then write a note about why or how it is relevant to documentary and the digital, even if it is your own peculiar view.
