What is available?
At the current time there are approximately 42 matches that meet the subject keyword search for Maps Databases using Horizon as the search engine. These range from Census Data to CD-ROM Atlases to TIGER Files, and so on.
Where do you find these resources?
All digitally imaged maps meeting these criteria can be found in the Government Documents Section of Joyner Library. These files are formatted as Computer Files or Maps. They are located behind the desk in the CD-ROM section of the Reference Office.
What kind of software and hardware is necessary to run these CD-ROM map images?
While there are a few CD images that are in MS-DOS format, the majority of the files require additional hardware and software to enable one to access the map images. Most files require one of the following: LANDVIEW II, DATAVIEW, ADOBE ACROBAT, or ARCVIEW/ ARCINFO.
