LOS ANGELES, Dec. 18 — With Judith Regan’s authors still reeling from their publisher’s abrupt dismissal, the sparring between the headline-making Ms. Regan and her former employer, Rupert Murdoch’s News Corporation, grew more intense, more personal and more specific today over allegations of anti-Semitism.

The News Corporation released what it described as notes from a heated telephone conversation on Friday between Ms. Regan and Mark Jackson, a top lawyer for HarperCollins, the company publishing division which included her imprint, ReganBooks — a conversation that News Corporation officials said was instrumental in her dismissal.

According to the notes, taken down by Mr. Jackson as the conversation unfolded, Ms. Regan protested that the publishing house had not supported her during last month’s firestorm over a confessional book by O.J. Simpson and related television program, which the News Corporation canceled in the wake of public protests and unease by some affiliate television stations.

“‘Of all people, the Jews should know about ganging up, finding common enemies and telling the big lie,’” Ms. Regan said, according to a transcript of Mr. Jackson’s notes provided by Gary Ginsberg, an executive vice president of the News Corporation.
