20 Nassau Street, Suite 247, Princeton, NJ 08540 is in the business of cataloging antiques and art. Egan believes a valuable collection deserves professional cataloging. His firm supports collectors in a number of ways, but the emphasis is on documentation. ACL records all information in a computer database. This data can be amended, added to, searched, sorted, and exported to suit the collector's needs.
All information is available to the collector in printed form.
ACL also does professional-quality photography, and photographs are converted to digital records. Digital systems like Kodak's Photo CD are capable of greater resolution than the photographic process, so there is no loss in quality when copies are made. There is also no deterioration with time, whereas the life of color photographs is measured in decades. If an image of the newly painted Mona Lisa could have been digitized in 1503, we would have a perfect benchmark for restoration. Having a collection cataloged professionally can save money.
