Price Berkley, the founder, editor and longtime publisher of Theatrical Index, the weekly trade publication that for nearly half a century has been consulted by anyone wanting to produce, finance, write about or possibly avoid a Broadway show, died on Sunday at his home in Manhattan. He was 92.

His niece, Linda Berman, confirmed the death. She and a nephew, Michael Golden, are his only survivors.

Berkley founded Theatrical Index in 1964 with a typewriter, a stapler and 16 subscribers. Minus the typewriter, and plus thousands of subscribers, it has changed little since then, and retains its original, humble form: a slim sheaf secured at the top with staples.

“People used to put it on a clipboard on their bulletin board, and they still do,” said Steve Bebout, who succeeded Berkley as editor-in-chief after his retirement in 2007. “That’s why it’s still stapled the way it is.”
