HOWTO Search For Public Domain ebooks Using Google Books and

If you are looking for electronic versions of old public domain books and journals you can get good results by using Google Books and together.

Instead click on the link to “All Files”, then download the PDF (or the DJVU, or the text extracted from the DJVU) from there.

There’s nothing to stop you searching for authors, title words of keywords as well. is used by projects other than Google Books. has the texts of many old books as well, and provides html and epub versions of illustrated books as well. But as a new resource with some rough edges, Google Books is a useful new research resource for historical sources.
