Casting around for something to watch that wasn't all boys all the time, I googled for lists of feminist anime a while back, and this was one of the recommended series. As a book person, the title jumped out at me. Having finally had a chance to check it out, I can now say that it's mostly quite good.
"Read or Die" started out as a series of pulp novels, then became a manga series, with a second spin off "Read or Dream" manga series set in the same universe, and finally got made into a direct to video miniseries, followed by a 26 episode TV series. The novels have never been translated into English, and I have not read the manga. But I have now watched both the miniseries and the TV series. Knowledge of the manga or novels is not necessary to enjoy either anime, but the extensive print based backstory appears in small unexplained details and lends the anime series a lot more texture and depth than it would have if it was a totally original creation. Also refreshingly, nobody brings the story to a halt to explain what is going on, yet at the same time, it's perfectly possible to figure out everything you need to know (Hollywood scriptwriters could learn a lot from this series).
Set in an alternate universe in which rare old books containing esoteric knowledge are the key to global power politics, Read or Die follows the adventures of the agents of the Special Operations Division of the British Library as they guard the UK against biblio-based threats. Like Mission Impossible meets the Avengers, as imagined by bibliophiles, with James Bond movie style villians.
( The miniseries, mostly spoiler free )The TV series is in some ways superior to the miniseries. There's less fanservice (a few moments every few episodes instead of every episode), the characterizations are sharper, and 26 episodes gives room for a bigger, more varied story.
( again, not many spoilers ) All in all, It's a very nice melding of sisterhood and girl power with high stakes spy action. I'm very glad to have watched both series, and I might even try to read the manga someday.
