While it is true that an enormous amount of good philatelic research
material is available online, millions of words of philatelic importance were written before the Internet was invented. Unlike academic disciplines with their well funded libraries and armies of grad student workers, most older philatelic literature and periodicals have never been scanned and many have only been scantily indexed. It is great fun to go through a box of old literature and periodicals and read interesting articles that are unobtainable online.
Thus it is a great event when a new web site offers interesting older philatelic literature and it is even better when that site is owned by a young professional philatelist as knowledgeable and easy to get along with as Matt Kewriga http://kewriga.com/. Older literature is inexpensive and extremely readable. Go to Matt’s site. You’ll have fun
