My great grandmother published a book of our genealogy. The only copy I can find is in the Mississippi Archives, and they won't copy it without the publisher's approval. The problem is the publisher was American Historical Co: new York. I can find no current contact information. THey seem to have published lots of genealogies and biographies in the first half of the 20th century and are now no more. Any help would be much appreciated on how to avoid copyright infringement, but still get to see my great-grandmother's book.
