Archiving Policy

All materials published by Pinagpala Publishing Services are officially archived in the National Library of the Philippines, as the company is a registered publisher under the National Book Development Board (NBDB) of the Philippines. In addition, our publications are indexed in reputable platforms such as Google Scholar, Zenodo, OpenAIRE, Philippine eJournals, ISSN, Google, Yahoo, Microsoft Bing, Google Books, and Google Play Books. This ensures that all publications are not only preserved as part of the nation's cultural and intellectual heritage but are also widely accessible to a global audience through trusted indexing platforms.
