My RA course asked me to select two resources to use for the program from their lists of general resources and genre-specific resources.
From the list of general resources, I chose NPR Books - mostly because I felt that choosing Goodreads was something of a cheat since I already had an account there. (I do realize that I don't make nearly enough use of it, and that's something I'm also trying to rectify.) I also made that selection because of NPR's general reputation of being thorough and thoughtful, and can't imagine their Books section being different from that.
My new place of work has developed a nine-week training course for readers' advisory. Part of this assignment involves creating a blog and posting to it, and I just happen to have this library-themed blog created and hosted, sitting empty waiting for inspiration.
