I have focused on only 3rd section, which is entirely appropriate for my research question. For my textual analysis, however, I will analyze Chapter 6: Fingerprints.

1. Introduction of Fingerprints:
2. Key components of the chapter:
A. Henry classification system of fingerprint
B. Automated fingerprint identification system (AFIS)
