So far, DPL has about 20,000 images cataloged. Images are scanned on a high-resolution scanner on Macintosh workstations, and any image correction is done with Adobe Photoshop. The preview and enhanced images are then stored on separate CDs on a CD-ROM array for access on demand from Everybody's Catalog. Thumbnail images are displayed with the brief record, from which the user can select a full, high-resolution image. DPL has provided Pentium workstations with a video accelerator and 21-inch monitors for patrons to access the collection.
Printing is available in preview or high-resolution modes.
However, access to electronic journal information is still in its infancy and there are presently a variety of different models emerging in the marketplace. These models sometimes offer overlapping access to full text information in a variety of ways. Although the Internet has long been a medium for experimental electronic serials, mainstream publishers are now beginning to embrace the Internet, particularly WWW technology, as a way to offer their publications to the international community. Although there appears to be widespread use of standard web technology to offer electronic serial publications, there are many nebulous areas including clear and understandable pricing algorithms, electronic page layout, copyright issues, backfile availability, guaranteed accessibility, and mirroring of data.
