521 libraries (461 buildings and 60 mobiles) currently under threat or recently closed (List below) out of 4517 in the UK (CILIP figures)
Summary

Well, not, “All Quiet” but still one of the quietest weekends for library news for quite a while.  Expect more confirmed cuts next week though, especially in Warwickshire.  HarperCollins have said ebooks lent at public libraries should self-destruct after 26 loans, to much disgust by librarians and users.  One commenter asks if HarperCollins want print books to be burnt after 26 issues too.
