Library Opening Hours in Brent

I remarked in my post on the opening of Willesden Library that it has different opening hours to what became standard as part of the Libraries Transformation Project.  Brent Libraries are due for another review, although I doubt whether it will be as far reaching as the 2011 one.  It would be interesting to see the data as to whether a 9am opening is preferable to (say) the equivalent time in the evening.  I have also heard people argue that Sunday opening would be welcome.  Willesden Library is the only Brent library to open on Sunday mornings as opposed to Sunday afternoons, so it will be interesting to see how popular that is.  Incidentally, I wonder how many Council libraries in the UK still open on Sundays at all?
