Many libraries in the US have a Friends of the Library volunteer group, or something similar. I volunteer at two of our local branches.
Just a FYI that you might have to be fingerprinted or do a background check. That was required for our county, as we are sometimes in close proximity to children.





Our County Library offers preloaded Kindles that you can check out for a month. Each one has a different genre on it.
Libraries are also where people who can’t afford air conditioning like to hang out, where classes for everything from yoga to crochet are offered and where I found out from a visiting ACA rep that I could save $600 a month on my health insurance.
