Scholarly preservation extends beyond the initial publication of an article. It involves the maintenance of reliable publication records, accurate bibliographic information, the identification of authoritative versions, and arrangements that support the future accessibility and integrity of published research.

This policy describes how CPRT provides access to its publications, supports the deposit of scholarly works in external repositories, communicates copyright and reuse conditions, and addresses enquiries concerning digital preservation and the scholarly record.

Access to Published Articles

CPRT operates under an immediate open access model. Published articles are made freely available through the journal's official website without subscription charges, reader access fees, or embargo periods. Readers may access and use the published content in accordance with the applicable open access licence.

The official article record provides the publication information necessary for scholarly identification, citation, and verification. Where applicable, this includes:

• The article title, author names, and institutional affiliations.
• The journal title and relevant publication information, including publication date, volume, and issue where assigned.
• The article's Digital Object Identifier (DOI), where assigned, or another official publication URL.
• The applicable copyright statement and open access licence.
• Relevant corrections, retractions, or other post-publication notices, where applicable.

The published Version of Record (VoR) is the authoritative scholarly version of an article made available by CPRT. It represents the publication following completion of the applicable editorial, peer-review, copyediting, and production processes.

Where an article has been corrected or retracted, readers should consult its official publication record and any associated notices to establish its current scholarly status. The journal recognises the importance of maintaining clear relationships between original publications and subsequent editorial updates.

Author Self-Archiving

CPRT supports the deposit and dissemination of scholarly research through institutional repositories, disciplinary repositories, personal academic websites, and other appropriate scholarly platforms. Authors retain copyright in their original contributions and may make authorised versions of their research available without an embargo imposed by the journal.

The journal permits authors to share the following manuscript versions, subject to applicable copyright and third-party rights:

• Preprint: The original manuscript prepared by the author before formal peer review, which may be shared through appropriate academic repositories or other scholarly communication channels.
• Author Accepted Manuscript (AAM): The manuscript accepted following peer review and editorial revision, before final publisher copyediting and typesetting.
• Version of Record (VoR): The definitive published version, including the final article text and official publication metadata, as made available by CPRT.

Deposited copies should include an accurate bibliographic citation, identify CPRT as the original journal of publication, and provide a link to the official article record or DOI where available. Earlier manuscript versions should be clearly distinguished from the final published version.

Authors are encouraged to select repositories that provide reliable institutional or disciplinary stewardship, appropriate descriptive metadata, and mechanisms for maintaining access to deposited materials. The choice of repository may affect discoverability, technical continuity, and long-term availability.

Self-archiving provides an additional route to accessing published scholarship and may contribute to wider distribution and preservation. However, the availability of an article in an external repository does not, by itself, establish that the article has been deposited in a formally managed long-term digital preservation service.

Copyright and Reuse

Authors retain copyright in their original scholarly contributions published in CPRT. The journal publishes articles under the Creative Commons Attribution 4.0 International License (CC BY 4.0).

Under CC BY 4.0, users may:

• Copy, download, reproduce, and redistribute licensed material in any medium or format.
• Translate, adapt, transform, and build upon the material.
• Reuse the material for educational, scholarly, commercial, and non-commercial purposes.

Reuse must comply with the licence conditions, including appropriate attribution, identification of the applicable licence, and an indication of changes where relevant. Users must not imply endorsement by the original authors or publisher, or impose additional restrictions that prevent others from exercising rights granted under the licence.

Third-party content, including photographs, illustrations, manuscript reproductions, translations, extended quotations, and archival materials, may be governed by separate copyright or permission arrangements. The article's CC BY 4.0 licence does not automatically apply to materials expressly excluded from its coverage.

Authors and readers should consult the journal's Copyright & Licensing Policy and Open Access Policy for further details concerning copyright ownership, attribution, permissible reuse, and author rights.

Digital Preservation and Scholarly Record

CPRT recognises the importance of digital preservation for maintaining the accessibility, integrity, and scholarly value of published research over time. Digital preservation involves more than making articles available on a journal website; it also concerns the continued accessibility of publication files, the reliability of descriptive metadata, the identification of authoritative versions, and arrangements for responding to potential technological or organisational disruptions.

The journal supports the maintenance of reliable publication records through its online publishing platform and recognises the value of appropriate preservation arrangements for the continuity of the scholarly record.

The following considerations guide the journal's approach to the preservation and accessibility of published research:

• Publication record integrity: Maintaining clear identification of published articles and their relevant bibliographic information, including author details, publication dates, and official article identifiers where assigned.
• Version identification: Distinguishing the published Version of Record from earlier manuscript versions and identifying relevant post-publication corrections or retractions.
• Metadata reliability: Supporting the accuracy and consistency of publication metadata used for scholarly citation, discovery, and identification.
• Repository dissemination: Encouraging authorised distribution through suitable institutional and subject repositories as an additional means of improving access and discoverability.
• Long-term accessibility: Recognising the need for appropriate technical and organisational arrangements that support access to scholarly content beyond its initial publication.

Where information concerning a specific preservation programme or archival arrangement is provided, its scope and operational status should be distinguished from the confirmed preservation status of individual articles or issues. This distinction helps authors, libraries, and readers assess the available evidence of long-term preservation without conflating organisational participation with completed archival deposit.

Preservation Enquiries

Authors, librarians, repository managers, indexing services, and readers may contact the editorial office for information concerning article access, repository deposit, publication records, and the journal's current digital preservation arrangements.

Enquiries may concern:

• Access to a published article or its official Version of Record.
• Author self-archiving permissions and repository deposit.
• Publication metadata, article identification, and citation information.
• Current preservation arrangements and information about available archival records.
• Questions concerning the relationship between the original publication and any corrections, retractions, or updated records.

When contacting the editorial office about a specific publication, enquirers are encouraged to provide the article title, author information, publication URL, or DOI where available. Such information assists the editorial office in identifying the relevant scholarly record and responding to the enquiry.
