The online Internet Archive copy is the same set of photographs, cropped and in greyscale, so the scan links open the same spread. Pages 502–503 (Mining) and 966–967 (Index) were not photographed. Gaps in table numbering (e.g. Agriculture Tables 2–3 and 11–17) are in the printed book itself.
Note: In the early books added to this website, cells that are marked blank may be blank because the original was blank, or because the large language model extracting the table had difficulty in reading the cell. Read the transcription notes for each table and check the original source when in doubt.
