Pitfalls to Avoid When Seeking PubMed Central Inclusion

Academic journals seeking inclusion in prominent abstract and citation databases like PubMed Central (PMC) must meet stringent criteria that go beyond mere publication output. While the provided sources do not detail the specific, exclusive requirements or common rejection pitfalls for PMC itself, they extensively outline the fundamental principles of transparency, ethics, and quality that underpin reputable scholarly publishing. These principles, embodied in frameworks such as the COPE Core Practices and the Principles of Transparency and Best Practice in Scholarly Publishing, are widely recognised by scholarly organizations and are implicitly or explicitly considered by major indexing services.

Lack of Transparency and a Professional Online Presence:

A journal's public face, particularly its website, is crucial. Pitfalls here include:

Misleading or Confusing Name: Using a journal name that could be easily confused with another existing journal or that misleads potential authors and readers about its scope, origin, or affiliations.
Substandard Website: Not having a properly supported, maintained, and secure website. The sources specifically recommend using HTTPS for security.
Missing or Unclear Essential Information: Failing to clearly display the journal's ISSN (separate for print and electronic versions), its aims and scope, target readership, and policies regarding manuscript types (e.g., policies on redundant publication).
Undocumented Policies: Not clearly articulating and publishing the journal's editorial, ethics, copyright, and fee policies directly on the website. The website must clearly show these policies and other required information.
Poor Archiving Plan: Not clearly indicating the journal's plan for electronic backup and long-term digital preservation of its content. PMC itself is mentioned as an example of an appropriate destination for archiving.
Non-Functional or Missing DOIs: Not utilising functioning DOIs for published papers is a transparency issue.
Inadequate Contact Information: Failing to provide clear contact information for the editorial team.
Website Application Issues: When applying, using the same URL for different required guidelines or policies instead of providing discrete URLs for each specific page.

Deficiencies in Publication Ethics and Policies:

Robust ethical standards are non-negotiable. Common mistakes involve:

Ignoring or Failing to Publish Research Ethics Guidelines: Not adhering to, or failing to publish clear guidelines aligned with disciplinary regulations and norms regarding the ethical conduct of research. This includes processes for reviewing work to ensure it conforms with guidelines on informed consent, institutional oversight, and prior ethics approval.
Lack of Misconduct Procedures: Not having clear processes or guidelines for promptly responding to suspected ethical breaches by authors, reviewers, and editors. Journals must take allegations seriously and have procedures to address and respond to complaints.
No Complaint/Appeal Process: Lacking a clearly described process for handling complaints and appeals against the journal, its staff, editorial board, or publisher.
Not Adhering to Core Standards: Failure to adhere to the COPE Core Practices and the Principles of Transparency and Best Practice in Scholarly Publishing. These principles are used for evaluation by various scholarly organisations.
Insufficient Data Policies: Not including clear policies on data availability or encouraging the use of reporting guidelines and registration where standard practice in the discipline. Also lacking processes for handling issues like data fabrication and falsification.
Poor Post-Publication Management: Not developing guidelines for post-publication discussions and corrections, including mechanisms for correcting, revising, or retracting articles when needed. Failing to promptly retract seriously flawed articles is viewed not as failure, but as responsible action. Journals must be willing to publish corrections, clarifications, retractions, and apologies when needed.
Unclear Intellectual Property Policies: Lack of clear policies on intellectual property, copyright, and publishing licenses.
Encouraging Misconduct: Having policies or statements that encourage or knowingly allow misconduct such as plagiarism, citation manipulation, or data falsification/fabrication.

Weak or Non-Transparent Peer Review:

A robust and transparent peer review process is fundamental to quality control. Pitfalls include:

Missing or Vague Policy: Not having or clearly indicating a peer review policy.
Undescribed Process: Failing to describe the type(s) of peer review process used (e.g., single-blind, double-blind, open review).
Lack of Procedures: Not having policies on specific peer review procedures, such as the use of author-recommended reviewers or masking of identities.
Breaching Confidentiality: Not maintaining the confidential nature of the review process. Information about a submission should be handled confidentially except for review purposes and investigating misconduct.
Bias in Decisions: Allowing commercial considerations (e.g., advertising revenue) to affect editorial decisions. Author fees or waiver status should not influence editorial decisions.
Editor Self-Publication Without Transparency: Editors handling their own submissions without an independent, transparent peer review process.

Credibility Issues with the Editorial Board:

The quality and integrity of the editorial board are reflections of the journal's standards. Pitfalls include:

Lack of Full Disclosure: Not listing the full names and affiliations of Editorial Board members on the journal website.
Outdated or False Listings: Having a board list that is not up to date or includes members who have not agreed to serve or are unaware of their affiliation.
Lack of Expertise: Not having credible experts on the board. Editorial board members should be experts in the journal's subject area. Requirements for qualifications may be assessed.
Unmanaged Conflicts of Interest: Failing to identify and manage conflicts of interest for board members.
Questionable Affiliations: Including Editorial Board Members with questionable affiliations (e.g., to journals flagged as suspicious) without addressing the issue.

Issues with Content Quality and Relevance:

The published content itself must meet certain standards. Pitfalls include:

Off-Scope Publications: Publishing manuscripts that do not fit the journal's stated scope.
Poor Quality Manuscripts: Accepting papers with poor quality or flawed methodology.
Ethical Non-Compliance in Research: Failing to ensure manuscripts comply with ethical standards for research.
Plagiarism: Not checking for plagiarism.
Citation Manipulation: Encouraging or allowing citation manipulation or having excessive author/journal self-citation rates. Self-citation should remain under 15%.

Operational Inefficiencies:

Consistent and reliable operations are expected. Pitfalls include:

Undescribed Frequency: Failing to clearly describe the journal's publishing frequency.
Inconsistent Schedule: Failing to keep to the publishing schedule consistently.
Significant Delays: Significant delays in the peer review process.

Conclusion

Based on the general principles for scholarly publishing detailed in the sources, aspiring indexing in databases like PMC necessitates strict adherence to standards of transparency, ethical conduct, editorial integrity, peer review quality, and content relevance. While the sources do not provide a PMC-specific checklist, the principles outlined by COPE and in the Principles of Transparency and Best Practice in Scholarly Publishing represent the fundamental requirements for a reputable journal. Ensuring clear, publicly available policies and procedures covering these areas is crucial to avoid the pitfalls that would likely prevent acceptance into any major indexing database.
