Not much luck so far! A Google search returned a few academic libraries and specialist libraries but no public library blogs in the UK. Plenty of US public libraries came up on Google and on a Bloglines blog search but nothing closer to home. A couple of articles referred to Gateshead Public Libraries but looking at their website it looks like the blog has gone - certainly no sign of an RSS feed or an ability to comment on news items listed.
I did find an online article by Ian Winship in Update's May 2004 edition which looks at using weblogs in libraries - Weblogs and RSS in information work but this again only refers to the Gateshead project.
Are there really no UK public library blogs out there???
