The Numeracy and Pedagogical Studies in Primary Education (NPPE) utilizes the Public Knowledge Project Private LOCKSS Network (PKP-PN) to ensure long-term digital preservation and permanent access to all published content. Through this distributed archiving system, participating libraries worldwide are authorized to create and maintain secure, enduring archives of the journal’s publications for purposes of preservation, restoration, and scholarly continuity.

This archiving policy guarantees that the scholarly work published in NPPE will remain accessible even in the event of data loss, technical failure, or other unforeseen circumstances. By participating in the PKP-LOCKSS Network, NPPE aligns with international standards for digital preservation and follows best practices recommended by the Directory of Open Access Journals (DOAJ) and the Committee on Publication Ethics (COPE).

The journal's commitment to sustainable open access ensures that all articles in mathematics education, numeracy, and pedagogical innovation at the primary level will continue to be available for researchers, educators, and the global academic community for the long term.
