Bibliography
You can find the bibliography at Special:Bibliography.
I've been using BibWiki for my bibliography, but haven't been happy with its import features, so I use BibDesk to manage a master bibliography, with inputs from RefWorks (because that's what we use at Cornell Library).
Workflow
I use BibDesk to run a master bibliography. It can look up Library of Congress catalog data, although the annotations from there often need cleaning. I can export a bibtex file to the wiki to allow citations in all these wiki pages.
Snags
Unfortunately, BibWiki requires a single closing brace on its own line to close a record in its bibtex format, while BibDesk as a rule puts the closing brace on the same line as the last field of a record in its bibtex export, so I have to run a text search-replace every time I export from BibDesk to BibWiki. A possible solution is to fix the BibWiki parser to be more general in detecting the end of a record, or have it move the curly braces before parsing. Another solution would be to re-compile BibDesk so that it put the closing brace on its own line.
