Yes and No. Every library is different. A university library may be better stocked, but my local library's computer section is mostly old books on outlook, Excel, and Photoshop. There are some coding books, but they're mostly old books on VB and the like that might be difficult for someone new to programming to setup. The topics on loops and branching and variables are probably all relevant, but it's harder to learn just by paper.
Our local library gets books only slightly slower than what I can get ordered online. From the time I ask for a book, they often have it on the shelf within a few days, with an automatic reservation for me sent by SMS for pickup at the local branch just outside the door. Of course this is the socialist country of Sweden and we love our libraries... :-)
Last time I got a ZX-spectrum coding book that a friend on a forum wrote. Before that some obscure manga comic book. That one took a few months because they had a hard time to find it, it was long out of print.
They are very open to suggestions even of odd books and very curious librarians, both young and old.
Here in the US, you can use interlibrary loan to get nearly any book from a public or university library. Worldcat [0] is a great resource for finding books in other libraries that can be sent to you free through ILL.
Mine has a place where we can make suggestions, but unless it is a university library where people donate money (Ex: Texas A&M) it might not have a high chance.
