Original images were scanned in color at 600 dpi on a
Microtek 9600XL scanner and saved as TIFF files. The TIFF
files were converted into the MrSID format at a compression
ratio of 12 to 1 using LizardTech's Geospatial Encoder 1.5
software. These MrSid files were then uploaded into the
CONTENTdm database at the Washington State University
Libraries.
