How do you get a library card when your address is a PMB

Some but not all libraries will offer access for a nominal fee. We are at present in alpine tx and the library here offers access at no charge. There is a lot going on here with a pipeline project so I think the local offer is pretty cool. If your local library does not offer this, approach a board member, chances are they might see the logic in out of area cards. Their support from the local tax base is likely under $5.00 per year per household so $10.00 for card might intrique them.
I love libraries
