Smith, a journalist experienced in eldercare issues, has written a handy, compact guidebook on ways to recognize and help with health, financial, and legal problems faced by aging parents. Part of ``The Working Caregiver'' series, Smith's book provides scores of useful tips to make life easier for both caregiver and parent. Specific timesavers and ``to do'' lists are part of each chapter. Caroline Rob and Janet Raynolds's The CareGiver's Guide ( LJ 10/15/91) offers more in-depth information on the changes accompanying aging, but this serves as an excellent introduction.
