Welcome to the OYB Bookstore!
I publish a whole line of OYB Press titles. And I resell a few rare, fine titles. This action happens 'above' in the main Books area of the site.
But there are still a bunch of noteworthy, hard-to-find, sleeper titles out there that I don't stock (no time or room at this point). For these titles I created this Amazon Associates store and present them here by subject.
When you order them thru Amazon, OYB gets a hefty portion of the proceeds due to being the "store" for them, for you (heck, if you buy anything at Amazon after going there from an OYB link, OYB gets a "store" payment).
