I should have added to the previous message that your local may be able to borrow the books listed on the web site or held by the Library of Congress and other libraries which have online catalogs. Your library may be able to find these books in other libraries that will lend them by using OCLC an national network of library holdings that includes a majority but not all large libraries in the country. So identify the titles you want and let your local library staff attempt to track them down for you. Dave
