--
One of the biggest problems facing many digital library projects is the lack of authoritative information on various technologies -- primarily information that can support decisionmaking in regard to their effectiveness for different tasks. With this report, Kenney and Rieger provide the kind of nitty-gritty technical information for the Kodak Photo CD technology that digital librarians need to make good decisions. This is not the first time that the Cornell University Library has provided essential technical information for digital library developers (see "Digital Imaging for Libraries and Archives," http://www.library.cornell.edu/preservation/dila.htm), and I hope that it isn't the last. This paper is characteristically thorough, well-researched and documented, and flawlessly presented in Adobe Acrobat format. It is chock-full of good advice, tables, diagrams, examples, and Web addresses for further information. This is an essential reference document for anyone working with Kodak Photo CDs. - Review by Roy Tennant

Technical decisions
- Digital Files Exist in Several Forms
- File formats (GIF, TIFF, JPEG, etc.)
- Objects scanned into digital files can be formatted according to several file formats. Portable Network Graphics (PNG), Graphics Interchange Format (GIF), and Joint Photographic Experts Group (JPEG) files can be displayed directly in a WWW browser.
- Other types, e.g., Tagged Image File Format (TIFF) must be displayed with an application external to the browser. JPEG files have the characteristic of being highly compressed and capable of describing detailed images with minimal bytes. However, substantial support remains for TIFFs.
