The Reference Section issues referral letters to those who wish to perform research in other libraries and research agencies. Reference interviews are conducted by the Reference Librarian or the Library Assistant before researchers are given referral letters.
All bona fide members of the Institute (currently enrolled students, faculty members, employees, interns, and residents) are eligible to request for referral letters at least a day before the intended date of visit to other libraries or research agencies. They must also satisfy the following requirements:
- valid DLSHSI identification card
- registered in the library for the current semester
- no outstanding accountability with the library
