Another one via Linguist List: Web resources for African languages (from “site editor” Jouni F. Maho). From the main page:

The main objective of this site is to provide easy access to online materials on African languages, with particular emphasis on materials that contain structural data. […] The site contains links to other sites hosting free accessible materials, either as online searchable databases or as downloadable files of various formats (PDFs, PS-files, Word-documents, etc.). Links to commercial enterprises won’t be added, as a rule.

A nice looking site, though (of course) in need of many more contributions.
