Series 4. Forensic Identification/Investigation Reference Material (FIRM), 1913-1996

This series contains loose articles, pamphlets, booklets, materials from binders, photocopies, etc. For the most part, these items were organized on the basis of what appeared to be the predominate topic to which they pertained such as handwriting, fingerprints, footwear, firearms, forensic science, evidence, fraud, light, photography, etc. The materials are mainly contemporary except for "Early Publications" and "Applied Science Institute/University".

"Early Publications" in this series include pamphlets printed in the 1920s to 1940s mostly regarding fingerprint identification, among other topics.

The "Applied Science Institute / University" material is an educational series of publications on multiple topics from an organization in Chicago. The items begin with the first edition from 1916 and extend to the 36th edition of 1993.
