351 libraries plus 26 mobiles currently under threat or recently closed (List below “News”)
Being the list below represents around a third of  authorities in the UK, the final figure could be from 800 to 1000.

Changes to the total
Minus 1 – Isle of Wight – 9 out of 11 are to close, 10 was the previous worst case figure (worst cases are counted towards the total, “some” or “several” closures are not).
Minus 1 – Birmingham – Tower Hill saved from closure as three other libraries lose days to compensate
 
News

Isle of Wight joins the list of councils whose closure programme would have been a national scandal this time last year.  Its cuts (9 out of 11 to close) dwarf those proposed by Wirral in 2009. News suggests bad news imminent from Worcestershire, Thanet, Gateshead and Swansea. Brighton joins the list (Hillingdon, Wirral, Devon and Staffordshire) who have gone on record saying they will not close any libraries.
