Friends of the Library programs in most of the cities I have lived in are quite active. Where I live now there are several used bookstores run with donated books, not ex-libris stuff. Find out where to donate used books and the books will be put to good use.
One of the very best ways you can support any library is to use it.
Rarely have I seen city or county meetings discuss “Number of cars with a ‘Friends of the Library’ bumper sticker on it” as a metric for funding. “Number of active residents using the library” as well as “Number of books checked out via X, Y and Z services” are certainly looked at to determine where they spend their money.
Use it or lose it. That is really true with the online service. If the one you like to use isn’t getting a lot of activity, they will drop it and increase funding to the ones more folks use.
