Librarians are no strangers to the blogging world and some of the earliest blogs i followed where indeed written by Librarians. The Librarian in Black blog by Sarah Houghton-Jan a Digital Futures Manager for the San José Public Library is definitely one that i have been keeping an eye on in a Library topic folder in my RSS reader over the years and always find interesting and valuable information.
Recently Sarah wrote a post on her blog that caught my attention about a new book published by LibWorld titled "Library Blogs Worldwide" in which she has written a chapter covering the United States Library blogging community (page 187).
The book was published via the Infobib LibWorld project and is available as a free download or a paperback from Lulu online publishers.
It offers thirty commentaries by local librarians on the state of library-related blogs in 29 countries! The forward by Walt Crawford provides a good summary of the volume and diversity that global library blogs offer.
In Sarah's chapter she asks the question "which came first, the librarian blog or the library blog?" She writes that the librarian did because they "began sharing information with each other and as more of us saw the power of the blogging medium, we began adopting the same techniques at work.". I agree with that answer and it probably mimics a lot of other industries and professions who have adopted blogging as part of their work 'duties' in the same manner.
Another good resource for comprehensive lists of blogs is the Blogging Libraries Wiki and an output of the LibWorld report is available from the LibWorld delicious account where they have tagged all the blogs mentioned in the book by country.
