Then go to:

manybooks.net to get actual text (should have every book--easy to find other sites if not), which can be downloaded into rtf.  Then put each into a Word file.  Fix formatting as necessary, to make sure nothing is out of place--add page numbers and header/footer.

In all, 100 Word docs.
