LC to begin converting images to JPEG 2000

An article at Libraryjournal.com describes a new collaboration between the Library of Congress and Xerox to convert as many as a million digital images, photographs and maps from the TIFF format to the neweer JPEG 200 format. The goal is to create a "leaner, faster" digital collection. Xerox will create a set of guidelines for converting TIFF files to JPEG 2000 which will then be turned over to LC and to the National Digital Information Infrastructure and Preservation Program (NDIIPP)

Digital Case, the digital library and repository for Case Western Reserve University, uses JPEG 2000 for delivery of images stored in Digital Case. In a fine case of hedging out bets, we continue to store archival images in TIFF format. The outcome of the LC project could help us determine if the time is right for future projects to create the original images in JPEG 2000 rather than in TIFF. JPEG 2000 is a "loss-less" format, as is TIFF.

Looks like all of our due diligence in selecting an image format for Digital Case should pay off.
