Scholarly feuds seldom end amicably, and nearly 35 years after President Richard M. Nixon resigned, a dispute involving his Watergate tapes would seem to be no exception.

A handful of historians and authors maintain that the most authoritative transcripts of those recordings include significant omissions and misrepresentations that could influence interpretations of the cover-up.

At the center of the quarrel is "Abuse of Power: The New Nixon Tapes," a 1997 collection of transcripts edited by Stanley I. Kutler, a pre-eminent historian of the Watergate era, that has become the standard reference. Mr. Kutler has been a hero to many people because of a lawsuit he brought with the nonprofit group Public Citizen that led to the release of 201 hours of recordings related to unethical or illegal activity in the Nixon White House.
