The Internet Archive item is labelled 1924-25; the cover reads 1924-26. Only tables are transcribed; the running text, photographs, the map and the appendix documents (treaty, rescripts, speeches) are not. Every text page was read. Printed totals that do not add up are kept as printed and noted; every such table was transcribed a second time independently, and disputed cells went to a third reader (agreement settles a cell; otherwise it is marked unreadable). The one-sentence context notes are written by the transcriber from the surrounding text.
