The Stamp Specialist is the title of a series of books on philatelic research written and edited for the advanced collector of postage stamps.
The books were published by H. L. Lindquist, 2 West 46 Street, New York City.
Twenty books were issued between 1939 and 1948.
Early books were paper bound, but the majority was hard-bound and each later book was usually popularly identified by the color of its hard cover.
Each book contains six or more studies of research by eminent philatelic experts, each related to a particular detailed philatelic subject.
