I work for the New York Public Library, and believe me, we wish we could be open all day every day.

Last year, city budget cuts took the libraries in Queens and Brooklyn from 6 day service to 5, and we managed to keep NYPL open 6 days, but with reduced hours.

That said, there's a lot of people who freelance out of our libraries, and as strange as it sounds, one guy launched his hedge fund out of our business library (we have a few free Bloomberg terminals).
