My first feed is for library technology: "Keep Up! Practical Emerging Library Technology. This blog was set up as a part of the "Keep Up! Practical Emerging Technologies for You and Your Library" workshop, presented in late 2005 and early 2006 by Michael Porter, Training and Support Coordinator at OCLC Western."
My next feed is for keeping up with Books: "NPR Topics: Books"
My next feed is for keeping up with book reviews: "Washington Post Book reviews"
And my last feed is for keeping up with web pages: "Librarians' Internet Index: New This Week. New and newly-discovered Web sites for librarians and everyone else, updated every Thursday morning. See more resources on our site, http://lii.org/."
I could not find any RSS feeds for libraries in trees, trees in libraries, or library cats.
