Digital Preservation & Long-Term Archiving Policy

  1. 1. Commitment to Permanent Access

    The Journal of Prevention, Diagnosis and Management of Human Diseases (JPDMHD) is committed to the permanent availability of all its published content. The journal recognises that digital content is vulnerable to technical failure, institutional change, and unforeseen discontinuation of publishing services. Long-term digital preservation is therefore a core responsibility of this journal.

    JPDMHD ensures that its published articles are deposited in recognised long-term preservation archives, with additional archiving services being progressively onboarded. This policy remains in effect regardless of any change in publisher, platform, or editorial team.

    2. Active and In-Progress Preservation Services

    JPDMHD currently participates in the PKP Preservation Network (PKP PN), which is confirmed and independently verifiable in the Keepers Registry (keepers.issn.org), the authoritative global record of which journals are preserved and by which service. Onboarding to CLOCKSS and the Global LOCKSS Network is in progress; this page will be updated as soon as those deposits are confirmed in the Keepers Registry.

    2.1 PKP Preservation Network (PKP PN) — Active

       
    What it is The PKP Preservation Network (PKP PN) is a free digital preservation service developed by the Public Knowledge Project (PKP) at Simon Fraser University, Canada. It is designed specifically for journals using Open Journal Systems (OJS) and uses LOCKSS technology to distribute and preserve journal content.
    How it works The PKP PN plugin, integrated directly into OJS, automatically deposits published article content into the PKP PN network nodes. No manual uploading is required. Content is deposited continuously with each new issue publication.
    Who manages it The PKP PN is a community-supported, not-for-profit service, free for all OJS-based journals. JPDMHD uses OJS as its publishing platform and participates in the PKP PN through the integrated OJS plugin.
    Keepers Registry JPDMHD is registered with PKP PN and listed in the Keepers Registry under ISSN 2799-1202, status "Preserved."

    3. Keepers Registry Verification

    The Keepers Registry (keepers.issn.org) is maintained by the ISSN International Centre and is the authoritative global directory that records which journals are archived by which preservation service. JPDMHD's PKP PN preservation is registered and verifiable in the Keepers Registry under ISSN 2799-1202.

    Researchers, librarians, and indexing evaluators can independently verify JPDMHD's current preservation status at:

    4. Continuity of Access Plan

    In the event that JPDMHD ceases publication or HM Publishers is unable to continue operating the journal, the following measures ensure permanent access to all published content:

    Scenario Continuity Measure
    Journal website becomes temporarily unavailable Content remains accessible via PKP PN nodes at participating institutions worldwide.
    Journal ceases publication permanently Deposited content is made available through the PKP PN network. All DOI links will be maintained through CrossRef.
    Publisher (HM Publishers) ceases operations HM Publishers commits to providing at least 6 months' advance notice, transferring all journal metadata and content to preservation archives, and ensuring all CrossRef DOI records remain active.
    Platform or hosting change All DOIs will be updated to point to the new platform. Archived copies in PKP PN will be maintained independently of the platform.

    5. Author Self-Archiving (Green Open Access)

    In addition to institutional archiving, JPDMHD actively encourages authors to self-archive their published work to maximise visibility and create additional preservation copies.

    Version May Authors Self-Archive? Permitted Repositories
    Submitted version (preprint) YES Any repository, including subject repositories (medRxiv, bioRxiv, Europe PMC) and institutional repositories
    Accepted manuscript (author's final peer-reviewed version) YES Any repository, immediately upon publication, with no embargo period
    Published version (Version of Record — PDF) YES Any repository. All articles are published under CC BY 4.0, which explicitly permits redistribution

    There is no embargo period. Authors may deposit any version of their article immediately upon publication. JPDMHD is listed in the Sherpa/Romeo open access and self-archiving policy directory at:

    https://v2.sherpa.ac.uk/id/publication?issn=2799-1202

    6. Persistent Article Identifiers (DOI)

    Every article published in JPDMHD is assigned a Digital Object Identifier (DOI) through CrossRef, ensuring permanent, stable linking regardless of changes to the journal website URL or hosting platform. DOIs are the most widely used persistent identifier in scholarly publishing and are required by major indexing services including Scopus, Web of Science, PubMed Central, and Embase.

    • DOI prefix: 10.55529
    • DOI registration service: CrossRef (crossref.org)
    • All DOIs are live and resolve correctly — verifiable at https://doi.org/10.55529/jpdmhd
    • DOIs remain permanently active even in the event of journal cessation, as CrossRef maintains the metadata record.
