This project is an effort to offer online a full-color set of Nevada Sanborn® and other town maps. There is no full set in any format or combination of formats available at any location in the state. This digital collection, as of the initial posting, totals 516 maps for 29 towns.
Most of the maps in this digital project were scanned from the original holdings in the Special Collections Department, Knowledge Center, University of Nevada, Reno, and the Nevada Historical Society, Reno. This web presentation is limited to 1923 dated maps inclusive. Both locations cited above also hold microfilm for the Library of Congress holdings from 1885–1950's. A subscription from Proquest© to an online set is available in the University Libraries and may be viewed externally by University of Nevada, Reno, affiliated people. Please see the Inventory for a detailed listing.
Several maps dating through 1923 and not held by a Nevada institution were located at other sites and arrangements were made to obtain a digital copy. As indicated on the Inventory, these include the California State University Northridge and the Library of Congress, Washington, D.C. We appreciate their assistance.
The maps in this web collection from either the Special Collections Department, Knowledge Center, University of Nevada, Reno or the Nevada Historical Society, Reno, were scanned by graduate library assistants between March 2007 and July 2008 on an Ideal Magnum Wide Format FSCX050 scanner at 300 dpi to create high resolution, uncompressed TIFF images. Early in 2004 with financial assistance from the Mary B. Ansari Endowment, the library acquired this IDEAL/Contex Magnum XL 54" Plus Color Scanner. It scans at 24 bit color, up to 2400 dpi and will scan media up to 0.6 inches thick and up to 54 inches wide. The scanner was manufactured in Denmark and distributed in the U.S. by Ideal Scanners & Systems and is considered to be one of the best front-loading large format scanners available at the time acquired. At the time of scanning for this project, the scanner was housed in Special Collections, Getchell Library, University of Nevada, Reno.
The JPEG files were derived from the TIFF files. The TIFF files were also converted into the DjVu® format at a compression ratio of up to 220:1 using LizardTech's DjVu® compression software. The image files all live on the UNR Libraries' NAS server. The TIFF files are converted into JPEG 2000 deliverable files via the CONTENTdm™ digital collection management software, then metadata was created for each image including web links to the three alternate image file formats. Of these, Djvu files are most easily displayed on desktop computers of limited capability or connectivity. A one-time download of the free DjVu browser plug-in is necessary and provided for this purpose. The metadata provides detailed information on the original and digital map. The JPEG 2000 format is used to present many oversized images in the maps collection. JPEG 2000 is a published international ISO standard (ISO 15444). Based on newer wavelet compression technology, it offers both lossless and lossy compression and facilitates zooming, panning, and clipping without the need for a plug-in.
