Yes, plenty.
J.K. Rowling has discussed the history of the magical world in plenty of places, including:
Supplementary books. Quidditch through the Ages, Fantastic Beasts and Where to Find Them and The Tales of Beedle the Bard, three books written in an in-universe style that were published by J.K. Rowling for Comic Relief.
Quidditch is mostly the history of the sport, while Beasts contains discussion of the history of magical zoology. Fragments in Tales, based on Dumbledore’s commentary.
Interviews, usually as fragments or comments on another question. Complete transcripts of most of her interviews are on Accio Quote.
Pottermore updates, usually in the “New from J.K. Rowling” sections. Most of this is based upon characters, objects or places in the story, but there’s some interesting stuff there.
Famous Wizard cards. Some of the tie-in video games feature Famous Wizard cards, analogous to the chocolate frog cards in the books. For some of the games, J.K. Rowling wrote the descriptions, so these are considered canon. The HP Lexicon has a complete list of cards.
A complete list of all of these articles and resources is almost certainly beyond the scope of this site, but this should give you an idea of where you might get started.
As for Voldemort’s history in particular, interviews and Pottermore are probably your best bet, although I expect to see more about Voldemort in future Pottermore updates.
Asking for recommendations for opinion-based or discussion articles, or good fanfiction that explores magical history, is likely to get closed on the main site, but one of the HP regulars in the site chatroom might be able to suggest something.
