Databases covering antiques and decorative art, fine art, or rare books are available.
These price guides are never inexpensive, but they are more convenient to use than printed guides. Most disks cover the material of a number of printed annuals, and they can be searched quickly and conveniently using the power of the computer. The price for a consolidated disk is often comparable to the total cost of a set of printed annuals. Every CD-ROM database comes with unique software to access it. Such databases should be evaluated first on their content.
