Summary
It is disturbing when public figures do not live up to one’s high expectations of them. It is perhaps not surprising, though, that Boris Johnson showed in the Telegraph that he was not aware that public libraries were a statutory service. It is more depressing when a schoolgirl has to point out how mistaken the head of the MLA is.  It does not bode well for public libraries that both Boris and Roy have announced themselves as keen on saving them.  With friends like these….
Oxfordshire – it’s volunteer libraries or nothing – Henley Standard. Council “is set on walking away from the service — perhaps initially offering a little bit of funding to support a new fashion for community libraries that would no doubt be pulled after a few years.”
Wales – councils to slash £175m as perfect storm hits – Wales Online
Wandsworth – wants a “Big Society” library at York Gardens (hours cut, IT suite lost, public space rented to private college, five staff to go, in most deprived ward – Independent
National News
Clarke rebuff for rightwing critics – Financial TimesOn Sunday there were reports that Oxfordshire County Council had reprieved closure-threatened libraries after Mr Cameron, who represents a constituency in the county, had expressed his displeasure. Tory MPs are receiving large volumes of e-mails from constituents over similar cuts.”

List of cuts by authority (click on name of authority for link to relevant report)
NB. From 2012, the MLA will be abolished – the Arts Council will take over its role for libraries with a budget of £3m rather than £13m.  Therefore, libraries start 2012 with £10m less, regardless of any further cuts. There are 151 authorities in England, 206 in the UK.
