NGGDPP Collection Extension

usageTrendFor the ten years before the collection was moved to the University of Nevada, Reno, Special Collections, annual on site usage had slowly declined from about 200 to between 120 and 140. With most of the files coming on-line, in-house usage fell to 96 in 2006 and 54 in 2007. The NBMG Information Office has in-house computers for the public to view the PDFs on-line. Because most of the files remaining at the NBMG are journal articles, theses, and newspaper clippings available from other sources and the PDFs are universally accessible on the Internet, in-house usage is likely to continue to decline. Annual on-line use is unknown because we presently do not have a reliable counter, but is definitely well over 100 and may well be in the 1000s.
