This is a fabulous amount of work. Thank you.
My only reminder would be that numbers aren't everything. Every library's selection is slightly different, and so is their traffic. I have cards for both Buffalo and New York.
New York's collection is far larger. But it is more esoteric and young adult-oriented, and has lots of Mobi and PDF, with less ePub. And nearly every newish book has a waiting list of 20-40+
Buffalo's collection is significantly smaller, but it has a larger selection of new books being added regularly, many are "popular" in their genres, and waiting lists, if it all, are 2-5 people. And it tends to focus more on ePub, less on PDF, and no Mobi.
