After some discussions, I realized that some of the books I have are fairly rare (especially outside Poland) and contain important historical information. I create this partial list of books I have access to, and their subjects, so that you may request information on any of those, or even borrow them. The below list is never complete, and won't list some genral books (like Davies God's Playground etc.) :>
