Out of the box, WordPress lists posts in the Dashboard in chronological order. This makes perfect sense when it is being used as a blogging platform or to publish content where the order of creation is the same as the most useful order of access.
But WordPress is used for all kinds of Web publications and outside of blogging, alphabetical order is probably a much handier (and commoner) way to list entries. Músgraí Ord Postaí sa Deais WP makes it do that.
Músgraí Ord Postaí ar Leathanaigh Chatagóra WP
This plug-in is, effectively, the half-twin of the Músgraí Ord Postaí ar Leathanaigh Chatagóra WP plug-in, which does exactly the same thing only it does it in the website's public view rather than in the Dashboard. There's a good chance that if you want one you'll probably want the other.
All I'm after doing is pouring these into the framework of a plug-in. The original code was published under CC BY-SA 3.0 and, in accordance with the Ts and Cs, I make my own modifications available under the same licence.

There's only one file in this plug-in: músgraí-ord-postaí-deais-wp.php. If reverse-alphabetical order is what you're after, and you're comfortable doing minor fiddling under the bonnet, go to line 62 and change $query->set('order','ASC'); to $query->set('order','DESC');. Símples!
