Q. I have what appears to be a very old Missale Roman book/bible.

Regarding the rare books you have acquired I suggest you look at “Your Old Books,” on the website of the Rare Books and Manuscripts Section of the Association of College and Research Libraries. http://www.rbms.info/yob.shtml  The site has excellent information about how to learn more about your books as well as advice about appraisals and marketing.   We do not do appraisals or research for books being offered for sale and we only purchase rare books from rare book dealers .

Thank you for submitting your inquiry to “Ask a Research Librarian” and good luck with your rare books.
