Fat Iguana I've learned them by hearth by now! :)
The only two books that could have been worth flipping through is the top book of each stand. Volume 1 and 2 of "The woman. In health and sickness." Published in 1952. It's some sort of medical book. Which I suppose is outdated by today's standards.
I did find an illustration of a boob one night I was going through it! I can confirm that they haven't changed much since then.
