An official publication of The United Postal Stationery Society is The Postal Stationery of the Philippines United States Administration 1898-1946 (note the doubling of "OF" in the cover title).
Copyright year is 1983.
A note states that "Much of the update information in this catalog was compiled by Eugene A. Garrett during the years 1977-78." Gene is, of course, well known in Philippine philately.
It has information on knives, envelope and card stock, weathering, shades of ink, quantities, and corner cards, among others.
The contents include envelopes, wrappers, postal cards and reply cards.
Comes with a supplement for prices.
Bought my copy in the 1990s by mail from a US dealer.
