The earlier book published by Universal Publishing Co of Port Washington NY was Dr. Walter Loeb's "Catalog of Paper Money Around the World." It was 75 pages, saddle stitched with card covers, published in 1961. In my inventory it is annotated as "one of the pioneer world paper money catalogs." Both of my copies were donated to the American Numismatic Association some years ago.

The Sten "ENCYCLOPEDIA of WORLD PAPER MONEY: An ILLUSTRATED GUIDE-INDEX Compiled as an aid in the IDENTIFICATION and TRANSLATION of all CURRENCY 1661-1964," known in short as the "Sten Encyclopedia," is all that Bruce described and more. Sten was apparently of Eastern European origin, and seemed to know Cyrillic scripts well. There are very useful transliteration tables for same, in different fonts, which I have referred to many, many times. There are also extensive listings of titles from Russian and other Cyrillic-inscribed notes. My copy of the original 1965 edition is tabbed, faded, and loved.

I also had the 1965/1972 edition, published in Port Washington / Roslyn NY, and attributed in my inventory as "Jolie Coins reprint."

The two-volumes-in-one reprint of Sten's "Banknotes of the World" (the book of which volumes 3 and 4 were lost at his death) was distributed in the US by Jolie Coins, and I have always assumed that they also reprinted it.

All of my Stens, save the tabbed volume mentioned above, also went to the ANA.

I could go on about Dr. Loeb, whom I never met, but fragments of whose collection I acquired after his death. The world paper money fraternity was pretty small in the late '60s.
