As academic journals play a critical role in disseminating research findings, it is essential they promote the ethical use of published content. Journals should clearly display licensing information to clarify the terms under which articles may be used, shared, and adapted. Standardized licenses, like Creative Commons (CC),  Open Data Commons (ODC) and Copyleft, facilitate lawful reuse.

Authors are responsible for making copyright and licensing decisions. Journals must support them with appropriate infrastructure, including intuitive web design, user experience, staff training, and awareness. Journals should also be prepared to address non-compliance or misuse through legal action when necessary. Plagiarism tools can be helpful in identifying non-compliance.

Displaying licensing information for published articles

Licenses should appear prominently on article pages in all formats (HTML, PDF, ePub) via logos or/and text, ideally near the title and author information. This enables readers to quickly understand content usage terms. A link to the full license text should be included to clarify rights and limitations.

Embedding license information into article metadata and ensuring it is machine-readable supports proper attribution and indexing by automated systems. This improves visibility, enables interoperability, facilitates text/data mining, informs users about use terms via search or third-party platforms, and supports stakeholders’ compliance verification.

Licensing details must appear in downloadable files like PDF to ensure offline clarity. All supplementary materials – datasets, images, videos, code – must have explicit licensing and ensure license consistency across content types. Some specific content, like software, may need a GNU license instead of CC.

Considerations for License Display

For optimal license display across formats, journals may consider:

1. HTML Articles

• Place license information in a consistent location on the article landing page (typically near the title, authors names, or at the end of the article).
• Use both license icon and text description.
• Link icon to full license text on Creative Commons website.
• Include metadata tags in the page header and use RDFa, microdata, or JSON-LD for machine-readability.
• Add license information in OAI-PMH metadata to improve discoverability.

2. PDF Articles

• Include a visible license statement preferably on the first page.
• Embed license in PDF metadata.

3. Supplementary Materials

• Clearly state the license for each file, especially if different from the main article.

4. Data and Software

• For datasets, include license information in both the README file and metadata.
• For accompanying software/code use suitable licenses like MIT, Apache 2.0, or GPL, which address attribution, modification, and compatibility.

Monitoring and enforcing compliance

Journals should review licensing practices regularly to align with standards. Preventing unauthorized use and responding to misuse is vital to maintaining the scholarly record. Cooperation with authors, institutions, and stakeholders is key.

Displaying licensing and copyright for the journal’s website

Journals must differentiate between licensing for individual articles and the journal website. For example, an open access journal may state ‘All rights reserved’ for website design and branding but should still show article-specific licenses. Omitting article licenses and using only ‘All rights reserved’ creates confusion and may violate publishing agreements with authors.
