The Library of Alexandria, http://www.bibalex.org/arabic/index.aspx, has a site, http://archive.bibalex.org/mybook/fp/, which provides

electronic books in image format.

These books are downloadable for free. The file format of the downloaded book is .DjVu.

Two sites, “FileExt”, http://filext.com/detaillist.php? extdetail=djvu, and “DjVuLibre”, http://djvulibre.djvuzone.org/, both

provide information about this kind of file.

For Windows users, the site LizardTech, http://www.lizardtech.com/, provides a DjVu Browser Plug-in for Windows Internet Explorer.

I downloaded one of the books from the geographical section (Ibn Battuuta), and downloaded the Browser Plug-in from LizardTech. The

system works well.
