The first thing to note is that the material contained herein is mostly derived from magazines printed between 1940 and 1947. The originals that I have been able to obtain are of highly variable quality, some badly yellowed from sulfite oxidation, some showing damage from having been wet at a time in the past. Many issues have had pages or parts of pages razored out; interestingly, very few show signs of having been torn out.
A small amount of material is taken from other sources, notably from scans of military manuals (TOs.)
The quality of the originals was also rather variable. Looking at the printing, I have concluded that the young men who served as "printers' devils" and who performed routine maintenance on the Linotypes and presses started disappearing into military service early on. Later, as one of the magazines apologized for, the supplies of raw paper were both curtailed and of inferior quality. Some magazines, and portions of others, were printed on unpolished, unbleached and/or uncalendered paper; the print quality on such paper, especially of images, is generally poor.
A bit later, page layout became somewhat less regular, with photos not laid out square to the page and lines of type not laid square to the column. Ink smears and over-inked letters became more common, and occasional lines of type were omitted, so that continuity was broken. Broken letters and mildly defective Linotype masters became much more common through the war.
The magazine collection that these pages are drawn from constitutes some 300 issues, not counting duplicates. With some of the magazines running to 400+ pages during the peak activity period of the war, it should be obvious that I have not scanned and processed all of them and that I am unlikely to last long enough to do so. Hence, the decision to change my focus from being an editor/compiler of articles and themed collections to being a research service.
Since it will not commonly be the case that the researcher will know in advance which pages to request, a number of sources of insight are provided:
