Read books on Asian art to learn more about the pieces in your collection. "Harvard Outline and Reading Lists for Oriental Art" is a good place to start if you're not sure where, or when, your Asian art was created. "Guide to Modern Japanese Woodblock Prints, 1900-1975" and "The Arts of China", provide good overviews of major Japanese and Chinese art. "Indian Art (World of Art)" is a good guide to Indian art. Paragon Book Gallery or Kinokuniya are good bookstores to find these titles.
