When I first moved into Pinoso I joined the library. I've just done the same here in Ciudad Rodrigo. Not exactly Neil Armstrong's one small step but a litttle sign that I actually live here.
It was rather nice how naive the system seemed. I didn't have to prove my address nor that I paid taxes in the area or anything - it was as though there was obviously no need to doubt anyone who simply wanted to join the library. The woman on the counter wrote my name down in a big, old fshioned book, which looked as though it may have been in use for the last twenty years or so and the card she handed over really is made from cardboard,the photo is stuck on with a pritt stick. Excellent.
