A federal judge said Thursday he will stop a new Texas law aimed at keeping sexually explicit materials off of school library shelves on the eve of the law going into effect, according to state attorneys and lawyers for a group who sued over the proposal. District Judge Alan D. Albright indicated during a hearing that he will grant a temporary injunction sought by a group of book groups and sellers, including two Texas bookstores, who sued the state over House Bill 900 in July, the group’s lawyers said in a statement.
