In philately, the Higgins & Gage World Postal Stationery Catalog is the most recent encyclopedic catalogue of postal stationery covering the whole world. Despite most volumes not having been updated for over thirty years, the catalogue and the H & G numbering system are still widely used by philatelists and stamp dealers although the values given in the catalogue are out of date. The catalogue was published between 1964 and 1989 and comprises nineteen alphabetical volumes with supplements. The earlier volumes were edited by Edward Fladung who worked with Alexander D. Gage in the production of the catalogue. Later editions were edited by Melvin Feiner.
