One thing I have found helpful in freeing up shelf space is to remove duplicate copies of albums. Sometimes these have come from an inherited collection, and sometimes from forgetfulness. Then there are those where I have bought a "spare" or a replacement when a disk has become noisy, and finally there are a few for which I have mono and stereo versions of the same recording. Surplus copies can go on shelves in the basement, and leave more room on the ready-use shelves.
