I live in a London borough where I have 5 libraries within pretty easy reach, 1 of which is right near school and the main library very close to home. So a good selection but I am getting soooooo frustrated by the lack of selection of books. I keep a list in my bag of books I fancy reading, that I've heard recommended by friends or on here or read reviews. Books that cross genres, eras, fiction and non fiction, newly published and older ones....generally at any given time I will have 20 + books on my list yet I will be extremely lucky to find a single one 
I ordered our last book club book but ended up borrowing it from a friend as it never came in (2 months later)
I know I should be grateful that we have libraries, especially as so many are closing, and I desperately want to support it, but it is pretty tricky.
No wonder the most borrowed author from libraries is James Patterson, there are tons of his books in there to borrow!
