I am the East Asian Librarian at Rutgers, The State University of New Jersey. I recently developed FOREASt, the Internet East Asian Library, which consists of over 100 free online resources for East Asian studies. The basic idea of FOREASt is to facilitate the discovery and use of open access resources with web 2.0 technologies--blogging, tagging, and social bookmarking. The main website of FOREASt is built on WordPress.com and all the resources covered by FOREASt are also bookmarked on del.icio.us, which reaches librarians and researchers active in different realms.
By all measures, FOREASt has had some initial success: there were over 700 hits to its WordPress site in the 48-hour period following my formal announcement to a librarians' listserv; collaborations with other librarians and scholars have started; some librarians have posted the link to FOREASt on their own subject guides or blogs. In retrospect, choosing WordPress.com to host the main site has been the key to these successes: it is relatively easy to set up, flexible, and fully functional.
