After saying it was sticking by the policy to only allow “approved” religious books in prisons, it seems the government has changed its mind:

The bureau has not abandoned the idea of creating such lists, Judi Simon Garrett, a spokeswoman, said in an e-mail message. But rather than packing away everything while those lists were compiled, the religious materials will remain on the shelves, Ms. Garrett explained.
In an e-mail message Wednesday, the bureau said: “In response to concerns expressed by members of several religious communities, the Bureau of Prisons has decided to alter its planned course of action with respect to the Chapel Library Project.
