This is a awsome compendium manual for investigators. Has probably 150 Occupations over 48 pages, has a small section on skills (duplicate from source book i think) and a 5 new skills depending on the edition you are using i would think ( Block, Roping, Disguise, Forensics, Hypnotism). Has a section on 1920's forensics but the scans seem to run short, abruptly stops at page 61 (chaosium product details indicate it has 62 so not sure if its missing info or its just some lame last page thats not included)
Worth its weight in gold if you have more than a few people making characters at the same time instead of fighting over the source book. Personally i would print out 2 copies if you have a large group. As for the Scans they are all well centered and clean, cover comes out beautifully on glossy paper.
