Perimenopause: Preparing for the Change, by Nancy Lee Teaff, MD, and Kim Wright Wiley (Prima Health, $12.95).

Synopsis: Forget worrying about turning 50; by 35 many women have begun an unpleasant 15-year slide toward “the change.”

Representative quote: “Why should we become so hypersensitive about the approach of menopause? A quick scan of the symptoms may convince you that you suffer all of them–and have, frankly, since birth.”

Noteworthy flaw: Suggests that women abandon coffee just when they need it most.

Tupperware: The Promise of Plastic in 1950s America, by Alison J. Clarke (Smithsonian Institution Press, $24.95).

Synopsis: The last aspect of American popular culture not yet given a book-length academic treatment is dutifully explored.

Representative quote: “Tupperware, then, epitomized this notion of the authentic commodity. It tapped into a lengthy intellectual debate established in the 1920s and 1930s regarding modernism, mass culture, and the tension between moral and aesthetic concerns.”

Noteworthy flaw: Thirty pages of notes, including: “Tupperware Product Catalogue-C, 1949, 6.”

Mommy, When Will the Lord Be Two? A Child’s Eye View of Being Jewish Today, by Ruth Seligman and Jonathan Mark (Kensington Books, $11).

Synopsis: Children say the darnedest things about Judaism.

Representative quote: “We go to synagogue, eat lunch and have play dates. Nina, age 7.”

Noteworthy flaw: Orthodox kids are a pretty serious bunch, and most quotes have the whimsy of “God is watching us every day. Grace, age 4.”
