I thought I would try using WikiArc to host crowd-sourced bibliographies, with the idea that they anybody can contribute to them, and that open access materials will be searchable using a Google custom search engine. I’ve started off with papers and books related to how archaeology and human palaeoecology can be used to inform sustainability and conservation biology, and you can read (and contribute to!) the bibliography here.
I’m unsure whether this idea has any mileage, but I’m eager to try. I’d like to have more open bibliographies on the site. Use the comments area below to suggest topics to cover.
