In
stamp collecting, a want list is simply a list of
postage stamps that the collector is seeking to acquire. They are the major tool by which collectors organize the construction of a collection, and
stamp dealers frequently advertise to collectors to "send us your want lists".Since most major countries have by now issued from 1,000 to 6,000 types of stamps, it usually difficult for even a single-country collector to remember what is still missing from a collection. Still, most stamps are cheap, and collectors frequently get started by acquiring one or more existing collections, which will include most of the common stamps. Then the problem is to get stamps to "fill the holes"; only a handful of dealers will have a complete stock, and so the want list may take on a life of its own as the collector carries it to stamp shows, mail copies to out-of-town dealers, and so forth, gradually crossing off entries as they are located and purchased.
