The whole collection comprises 23,925 print and non-print books, journals, theses and dissertations, audio-visual and cartographic materials, and reprints.
The Library aims to increase wider access to electronic resources. The University Library subscribes to 48 online databases like multidisciplinary online databases (e.g. ScienceDirect, Scopus, Proquest, EBSCO, Springerlink, Annual Reviews, JSTOR, RGPL), e-book collections (e.g. GVRL, Oxford, Springer, Cambridge, EBSCO, CRCNetbase), and subject-specific publications under Science, Nature, Mathscinet, and AIP that are accessible on and off campus.
The UP MSI Library houses the Institute’s significant contributions to tropical marine science since its establishment in 1974. ISI and non-ISI publications in national and international journals, conference proceedings, books, and book chapters are regularly updated and managed in a database. Local databases of literature on seaweeds, invertebrates, Bolinao-based studies, and the West Philippine Sea are also maintained. A notable contribution is the development of the Philippine marine biodiversity database.
