I recently found a list of the top 100 blogs for librarians at : http://www.bachelorsdegreeonline.com/blog/2009/100-best-blogs-for-librarians-of-the-future/
I’m not sure that these are the best 100 blogs out there for librarians. However, it is a good list of some of the best known blogs out there in librarianship. This site categorizes the blogs into convenient topics. It also provides a short summary of the blog in question. All in all, this is a great site to see what type of blogs exist for librarians and what people are saying about the profession. Lastly, it’s a great place to begin to find out what people are saying about topics in librarianship on the Internet.
