EFO Bibliography

Needless to say, every issue of The EFO Collector, the publication of the EFO Collectors' Club, is an excellent reference on EFOs. For membership, click here.

J. M. Baxter: Printing Stamps and Engraving
164 pages, published in 1939 and out-of-print, this book remains a main resource for the EFO Collector. It explains the engraving process in great detail, and since many U.S. stamps were printed by engraving, it sheds light on what can go wrong during the production of engraved stamps.


Stephen R. Datz: 2005 Catalogue of Errors on U.S. Postage Stamps, 13th Edition
This is the standard reference for U.S EFOs. Printed in color, it provides information on EFOs, including rarity and price information. 208 pages. You might be able to purchase it from stamp supply dealers, as it was not available through its publisher's website as of August 2009..

Part III examines other perforating errors (i.e., misaligned perforating errors, blind perforations, missing perforation, little/large/double/elongated and overlapping perforation and freak strikes of the perforator).

Joseph Monteiro:Printing and Perforating Errors of Pastage Stamps in Canada (1953-2009): An Analysis
Click here for more information on purchasing this book.

The book provides an analytical methodology to understanding and evaluating printing and perforating errors. It classifies errors by type and provides the necessary knowledge to enable the reader to analyze how errors can occur and what is impossible. For example, if a stamp was engraved, then forgeries that use photo or lithography can be easily identified. If a stamp is printed in sheets of four panes of 50 stamps, then we know that a sheet with an error on each stamp must produce a minimum of 200 stamps. If a T-comb perforator is used, one knows what type of part perforating error is likely to arise. Its approach is similar to Abstract Algebra. It attempts to provide an educational and analytical approach to philately so as to place it on a sound foundation.
