I liked this book, but pieces of it puzzled me. For example, the author spends a significant amount of time discussing Second Life. However, she also never actually gave me a reason to care about librarians on Second Life basically being librarians.
I agreed with the book's central hypothesis, which was: librarians are awesome! Beyond that, it told me a lot of things I already knew (libraries are underfunded! Libraries often have to be totally technologically innovative! Librarians make lots of jokes about being spinsters with cats who wear glasses on a chain! There is often Division between academic/research and public libraries!) and left me feeling a little depressed. Most books about literacy tend to have this effect, as I'll get halfway through the essay before wondering what the world's coming to that people don't seem to realize the value of reading (etc., etc.)
In any case, it was a decent read, but it's not going on my favorites list any time soon.
