In some ways, of course, moms take a lot of abuse, but that's what they're there for. In these three cases it's very good-natured, enjoyable abuse. For his book (Dolphin, paper, $6.95), Bernstein, a senior writer for PEOPLE, interviewed the mothers of such people as Bob Dylan, Neil Sedaka, Marvin Mitchelson and Melissa Manchester. Joyce Brothers' mother, Estelle Bauer, said her role in her daughter's career is to "make sure she looks okay. I make sure her hair looks right. I'm her biggest critic." Dylan's mother, Beatty Rutman, says she loves his music. "But I don't think he was ever the greatest singer. He was never an opera star." There's a chapter on Bernstein's mother too, at her request. "I deserve a chapter," she told him. "Is it my fault you're not famous?" Paget and Majzlin subtitled their book (St. Martin's, paper, $5.95) "the official survival manual for children ages 20 to 60." They warn the visiting child to prepare to be trotted out for such activities as "the Crestwood Community Theater production of Medea" or "a 'Name the Hotel Dining Room' contest at the Sunshine Valley Motor Lodge." The authors' level of expertise is most apparent in this suggestion for a never-tail present: "A box of lovely handkerchiefs is a NICE GIFT" Decorated with photographs of the mothers of such people as Hugh Hefner, Franz Kafka and Martina Navratilova, More Momilies (Ballantine, paper, $2.95) includes favorite motherly sayings sent in by readers of Slung's first book on the subject, as well as more of her reminiscences. Some examples: "Look at me when I'm talking to you." "And this time make sure you use soap!"
