Online resources are of three types: digital collections, online exhibits, and digitized books.
The library’s digital presence is limited due in part to the fragility of bound materials (scrapbooks, newspapers, books, diaries), a policy of only digitizing single sheet items (set by the National Archives), and copyright issues.
Digitized materials are organized into three collections as part of New Mexico Digital Collections, which is maintained by the University of New Mexico:
- Maps Collection (a sample of about 40 historic maps)
- Graphics Collection (nearly 350 graphics including architectural drawings, lithographs, posters, menus, political cartoons, and illustrations from Harper’s Weekly magazine)
- Documents Collection (550 documents such as letters, broadsides, sheet music, scrapbooks)
