Just to add a little more on the topic of RSS – I’ve also been reminded of the excellent service from the Library of the University of California.
INFOMINE is a virtual library of Internet resources relevant to faculty, students, and research staff at the university level. It contains useful Internet resources such as databases, electronic journals, electronic books, bulletin boards, mailing lists, online library card catalogs, articles, directories of researchers, and many other types of information.
Do a search; browse or search by subject category; pick up the What’s New RSS feed or email alert service; wander over to the General Reference; check out the Other Search Tools; or visit the INFOMINE blog.
