National Genealogical Society of Arlington, VA has turned over most of their genealogical book holdings to the St. Louis MO County Library. Depending on your receiving library's policies on interlibrary loan, you may be able to interlibrary loan some of NGS's books. I have searched very briefly their catalog at http://www.slcl.lib.mo.us You may search by title, author, subject, keyword or call number. Unless noted otherwise, you probably can order interlibrary loan of books online and fill out your request http://www.slcl.lib.mo.us/ill/ill_book.htm I just checked on some of the books which Rosalie Edith Davis has compiled for Hanover and Louisa Cos. and I see that some of them are available. Take good care of these books, for posterity's sake! Happy hunting. E.W.Wallace
