Digitizing the Collection
JJT INC., of Austin, Texas, the Library's pictorial image contractor, produced the digital images in this collection in 1999. The company's scanning setup brings together a digital camera manufactured in Germany with JJT's custom software.
An uncompressed archival or master file was produced for each photograph, as well as three derivative files. The level of resolution employed for the Library's archival pictorial-image files is now ranging from 3000x2000 pixels to 5000x4000 pixels, depending on the types of original materials.
Duplicate images appear on this site. Multiple photographic prints (for example, enlargements, reprints, and contact prints) may exist for a single image. Therefore, although each physical item appears only once, there is some degree of image overlap.
