Abstract:
Statement of the Problem / Objectives: This study examined the Class S subset of the College of
Forestry and Natural Resources (CFNR) Library, UPLB. It determined how many distinct titles
could be assigned to forestry-related subject groupings based on the Bachelor of Science in
Forestry curriculum and described subject distribution, publication years, and Filipiniana and nonFilipiniana profile.
Methods: A descriptive quantitative design was used to analyze 1,961 Class S record-level entries
from a 5,364-volume working collection. Combining duplicate copies and repeated title entries
yielded 1,367 distinct titles. Coders used titles, Library of Congress call numbers, and curriculumbased decision rules to assign titles conservatively to five subject groupings. The principal
researcher reviewed the full dataset. Unassigned titles were categorized by reason for nonassignment. The same title-level publication years were used for five-year periods across all dated
titles and broader periods within assigned subject groupings. The content-based Filipiniana profile
was summarized separately from curriculum assignment.
Results: Of 1,367 distinct titles, 720 (52.67%) were assigned and 647 (47.33%) remained
unassigned. Forest Resource Management and Silviculture contained 490 titles (68.06% of
assigned titles). Assigned records represented 53 course codes across five analytical groupings.
The content-based Filipiniana profile comprised 388 Filipiniana and 979 non-Filipiniana titles.
Publication years were usable for 1,315 titles; 52 lacked a usable year, including 25 assigned titles.
Among assigned titles, 531 (73.75%) were dated before 1990 and 12 (1.67%) from 2010 to 2019.
Conclusion: Bibliographic curriculum alignment was partial and uneven, and assigned titles were
concentrated in older publication periods. The results support collection review, acquisition
planning, updating, and faculty consultation, but do not establish prescribed reading or overall
collection adequacy.
Originality: The paper shows how a specialized academic library can convert legacy bibliographic
records into curriculum-linked planning evidence through distinct-title analysis, conservative
subject assignment, and coded non-assignment. It treats non-assignment as meaningful evidence
rather than as missing data.
