There's a new compendium of library blogs called "Libworld -library blogging worldwide" You can download it as a pdf, or buy the paperback at Lulu.com. Its authors, Germans Christian Hauschke, Nadine Ullmann, Sarah Lohre describe it thus:
On April, 23rd 2007 a series of postings started on Infobib.de, where guest authors from all over the world introduced the library and library related blogs of their own country. This book is a collection of 30 revised LibWorld articles, accompanied by a foreword by Walt Crawford. Included are articles about the blogosphere of: Argentina, Australia, Austria, Belarus, Belgium, Brazil, Canada, Denmark, Finland, France, Greece, Hungary, Iran, Italy, Japan, Latvia, Malawi, Netherlands, New Zealand, Norway, Peru, Puerto Rico, Russia, Singapore, Spain, Sweden, Switzerland, Trinidad & Tobago, USA.
The book is more a description of the library blogosphere in these various countries than a comprehensive list. Nonetheless, I would like to thank the authors for taking into consideration the bandwidth concerns voiced by Google (who own and manage the Blogger.com servers), and for honoring our request that Knowbodies not be mentioned in the book.
