From your question I think it's the 1919-23 definitives you're after, & for this sort of specialisation you need
1) Polskie Znaki Pocztowe (PZP) Hardcover)
The first edition was published in Bialystock in 1938 & is, obviously, quite hard to find. The edition we mainly use is from 1960, issued to coincide with the 100th anniv. of Poland #1 & is a virtual reprint of 1938 with additions. It's a set of 5 volumes published between 1960-73. Volume 1 covers the pre-war period to 1939. It's highly specialised with, where available, printing figures & dates, paper & perf varieties, info on errors, proofs etc. It's all you'll ever need on this period.
A less specialised version is
2) Katalog Specjalizowany Znakow Pocztowych Ziem Polskich
This is a 4-volume paperback edition, mine is the last (1990) edition &, again, it's volume 1 that is pre-war. Although less specialised than PZP it still has lots of info on perfs, papers & printing figures.
The above two are in Polish.
3) Various articles on Polish pre-war stamps by Lieutenant-Colonel Reginald Nesbitt Wingfield Larking CBE. Larking was in Poland between 1918-21 as part of the international delegation overseeing the welfare of Polish POWs. He was a serious collector of Polish stamps & wrote many articles for Gibbons Stamp Monthly which have been reprinted by Polonus in Chicago & they have all their monthlies for sale, so that is source for English-speaking collectors.
4) Polish Definitive Issues 1920-1925, Ron Negus, Edinburgh 1959.
A 22 page booklet which summarizes these issues in detail. Another valuable source for English-speaking collectors.
As an example of PZP for review purposes here's what they've got for the perf varieties on the various papers of the 1920-22 definitives, Scott 150-152C.
One day I'll sort out my 5 tightly-packed stockbook pages of this issue
Hope this helps, cheers, Rick
