332 libraries plus 22 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.

The figures have changed because:
Plus 7 – Conwy may close 7 out of 12.
Plus 8 – Northamptonshire  has announced 8 possible closures (out of 38) plus 2 mobiles

Mr Pickles is quoted today as saying: “Before we see libraries cut and all these kinds of things, I want to see councils merge their back office functions ….I would like to see them sharing chief executives, their legal department, their accounts department, their payroll, their IT, their planning, their education support functions.  And when they have done all that, if they feel they have to close libraries, they should talk to me again.”
