Barkay published a book about the find in 1986, but recent advances in computer technology have helped researchers discover additional verses on the silver scrolls. The new research technique revealed that the scroll contains other verses from the Pentateuch. Barkay has written a manuscript about these other finds and plans to publish it in the near future.
My emphasis. According to Yigal Levin on the ANE list, who gets it from Barkay himself, the additional verse (he only mentions one) is Deuternomy 7:9.
