Today is a s-s-s-l-l-l-o-o-ow-w-w-w day in terms of blog fodder, so I decided to treat you to a Weird Book Room Update one (working ) day early!

This time around, our update’s weird book of the week is “What Not to Wear on a Horse” by Ginny Oakley and Stephanie Soskin, just in case you were worried your jodphurs might clash with your riding crop. Is it appropriate to wear argyle on an appaloosa? Plaid on a pony? Stripes on a stallion? You’ll have to read the book to find out.

Rounding out the selection are Flow: The Cultural Story of Menstruation by Elissa Stein and Susan Kim, (for everything you ever wanted to know about the joy of menses), The How and Why Wonder Book of Guns by Irving Robbin, and of course, Was Karl Marx a Satanist?

For the others from this week’s update, and over 75 weird books to choose from, head over to the AbeBooks Weird Book Room.
