Become a librarian

All good librarians keep tabs on both current and classic book titles. As a programmer you too should develop a set of current and classic books for your professional library.

Current books will probably not become classics but do keep you up on the current state-of-the-art or technology.

Classics live forever. Some are well known such as the Knuth series. Others are less well known, e.g. How To Solve It, Programming Pearls.

And all good librarians just love to have others check out their books ... just make sure you have your name in them and periodically, check the books you have checked out from others and return them.
