I have a series of books which I would like to scan and add to the collection. They were written between 1900 and 1930 prior to Library of Congress numbers. They all have a copyright page. These books have been recently been republished by different publishers which give them an ISBN. But of course these ISBN are for the newer reprint. What should I do about no ISBN? All of the books without ISBN are available from the library. None of the more current reprints are available from the library. Jim Nuttall
