SEMI-ANNUAL SAVINGS: Taschen bookstores. So browsable. So people-watchable. And the art-and-photo-celebrating books, those hefty tomes, nearly the size of a steamliner trunk? So desirable. So when the Warehouse Sale comes along, as it does every once in a good while, we're on it, or try to be. The sale books are discounted from 50-to-75-percent, there might be some damage or wear-and-tear here and there, and many will have lived a noble life as display copies. You can feel good that many people enjoyed thumbing through the book you're buying. Some community spirit in that: SALE DATES: Friday, January 22nd through Sunday, January 24th, at the Taschen stores in Beverly Hills and at Farmers Market.
