17th century. That's getting easier. Google books is systematically entering all the pre 1900 books from Michigan and Princeton and a number of similar places. They've already done quite a bit from the Bodlean. It is actually revolutionizing our ability to make use of such sources: 5 years from now everything in print should be available. I was challenged over a 19th century printers manual two months ago, and found several copies of all 3 editions on GS. The hardest period will be 1900-2000, material protected by copyright but not generally available. But before I started in on GB, I would first try to see if the book existed, and I would ask you to give a catalog record for any library that has it. I don't think you would be able to, because I do not think there are any 17th century russian books on the subject. Had you been cleverer & said 1910s and named an actual book, then I'd find which library held it and go there or get a photocopy or a scan. You would then be claiming it's not in any library or bibliography; the likelihood of that is extraordinarily low, Extraordinary claims of that sort require extraordinary proof, and I would ask you to scan the title page. In a recent really angry WP discussion, on the Internet Troll Squads, scans of Russian magazine articles were in fact provided. There are hundreds of people on WP who read Russian very well.
