Among the things my dad enjoyed is history, particularly the history of the Arab people. Here's a link to a website he had bookmarked about the Arab dynasties and leaders. Enjoy!

This was a bookmark that he had made himself, having just learned to use a computer not too long ago... it's endearing to know that he finally gave in to the PC that used to burn his eyes. Just one more thing to miss about him! :-)
