Press release: LexisNexis, University of Maryland Team Up to Preserve Images of U.S. Serial Set Maps: “The University of Maryland is providing the original maps so LexisNexis can rescan the collection into high-resolution digital images in color and black and white. Current scans taken from microfiche cannot provide the color or the same clarity as a scan from the original maps…The information in the Serial Set is arguably the most important historical information source in GPO’s long history, said Dr. Charles Lowry, University of Maryland Dean of Libraries and Professor of the College of Information Studies.”
