I assume you want to focus on military ammunition, not all the commercial and sporting stuff. That will help narrow the recommendations.
And, it sounds like you are more interested in the markings, than in technical details of construction.
Since you mentioned the Soviet Cannon book,it sounds like you are not just interested in “small arms” but also into at least medium caliber stuff as well.
The Ammunition Bibliography on the main IAA site may be helpful. http://cartridgecollectors.org/bibliography.htm
In addition to books, you may want to include digital references, many of which are free and can be downloaded, and others which you can link to.
In this category, I highly recommend the excellent website by Tony Williams http://www.quarry.nildram.co.uk/ammotables.htm Tony is also author of numerous excellent books on history of modern military weapons and ammunition- some of the very few that treat them as an integrated package, not guns in one book, ammo in another, and applications where both were used as yet another separate topic.
Several people provide digital copies of reference publications on CD/DVD usually with multiple books and at a price less than even one hard copy manual would be, and they have the advantage of being searchable.
One can never have too many references.
Two books I highly recommend for your library would be:
a. “.30-06” by Chris Punnett, the IAA Journal editor, which is loaded with info on that caliber ammunition by every maker and country he could find, and includes a lot of great history on the companies which is useful for other calibers as well.
b. History of Modern U.S. Military Small Arms Ammunition by Hackley, Woodin & Scranton with two volumes out covering 1880-1940, and 1941-45 respectively, and a third volume covering post 1945 eagerly awaited but with an uncertain publication date. Unbelievably well researched, written and illustrated with details on not just the common production stuff, but also the really oddball experimental items and obscure calibers for special purpose use.
