IN THE Nixon Administration, she had the kind of access that amazed veteran White House correspondents and she became a virtual one-woman bureau for dispensing upbeat, good news about the president and his wife and daughters.

In the Ford years, her say-nothing-but-nice-things brand of journalism made her byline appear frequently in the more widely-circulated women's magazines such as McCall's and the Ladies Home Journal.

Now with the Carters, free-lancer Trude B. Feldman is once again compiling a list of credits in the Reader's Guide to Periodicals that may someday make future historians wonder if she was the only reporter presidents and first ladies would consistently let near them in the 1970s.

The titles included: Rosalynn Carter's "My Remarkable Mother," Jimmy Carter's "My First Year," Chip and Caron Carter's separation "crisis."

And now, in the current Ladies Home Journal, there is a defense of embattles White House chief of staff Hamilton Jordan, denying virtually everything unflattering ever written about him and pointing out that he writes poetry and loves children and is good to his mother.

With Carter, Feldman can get the kind of Oval Office interviews that are denied to political writers from the most prestigious and influential publications in the country.

She has had at least two exclusive interviews with the president in recent months and that's two more than some of the big-name journalists have ever had. m

"She's had more one-on-ones with presidents than anyone," complains one important correspondent. "Newsweek magazine had only had one interview with Carter since July 1978."

Feldman, daughter of one highly respsected rabbi and sister of another, strings for a number of Jewish publications. When Israeli Prime Minister Menachem Begin gave a dinner at Blair House attended by President Carter on March 29, she was one of three journalists invited.

Lenore Hershey, editor of the Ladies Home Journal, came back from a meeting in Washington with President Carter late in 1978, absolutely convinced that Feldman had suggested the Camp David summit.

Feldman says that an interview she had with President Carter on the Middle East "might have triggered" the summit idea in his mind but that she does not want anyone thinking that she has ever taken any credit for the idea.

Feldman resents any implication that first families and White House officials such as Jordan cooperate with her when they shun other journalists because they like what she writes.

"Persistence" is the key to her success, she says, adding that Mary Hoyt, Mrs. Carter's press secretary, authorized one of Feldman's stories and sat in on the interviews.Presidential press secretary Jody Powell authorized the other two, Feldman says, but did not monitor the interviews.

The HEW has issued a nine-page memorandum on the "Use of Gender-Specific Terminology."

It is directed to the attention of "All Secretaries and Typists," sex unspecified.

They are reminded that the Assistant Secretary for Management and Budget will not "approve any functional statement containing gender-specific terminology" and will return offensive errors to be redone.

"Manpower" is a no-no. So are "man-years" and just plain "he." Suggested substitutes are "human resources," "staff years" or "person years" and "he/she," "person" or another neutral term.

Kennedy watchers are staring hard at the third-finger, left hand on both Sen. Edward M. (Ted) Kennedy and his wife Joan everytime they are photographed together. Neither one has started wearing their wedding bands again. And with Mrs. Kennedy, those who know her consider this a significant barometer of how hard she will campaign . . . Former Iranian Ambassador Ardeshir Zahedi's friends say he was in New York last week to be with the Shah . . . Actor Jason Richards, walking into a club the other night and neither recognizing anyone he knew nor being recognized by anyone he might want to know, turned around and walked right back out again . . . Former Secretary of State Henry Kissinger, who doesn't give compliments easily, autographed a copy of his book to Council of Economic Advisors chairman Charles Schultze "To one of the brightest men I know." . . . Columnist Tom Braden's wife, Joan, who wrote one of the first "why-I-separated" stories on Joan Kennedy for one of the women's magazines last year, is being offered a lot of money by a European-oriented writers' syndicate to profile all the Kennedy women she has known so well for so many years.Braden, who once hoped to be Jackie Kennedy's social secretary before the first lady vetoed the idea, worked on both Jack and Bobby Kennedy's campaigns.
