Strengthening Journals. Empowering Societies.
Caleo partners with academic societies to improve the quality, reach, and sustainability of their journals. Your society retains full editorial and strategic control. We provide the operational infrastructure, publishing expertise, and advocacy to support that.
Our team has supported and grown more than 150 journals. The range of that work, from small society titles to high-impact international publications, has shaped a practical understanding of what works at different scales.
We work with editors and society boards to improve visibility, streamline workflows, and meet indexing requirements. Societies can engage us for full operational management of the publishing process or for targeted support in specific areas such as production, hosting, or indexing consultancy. Where external providers are involved, we negotiate agreements on your behalf to ensure the right balance of quality and cost.
Each partnership is structured around the journal's identity, the society's priorities, and a realistic assessment of where the greatest opportunities lie. Decisions are made collaboratively, processes are documented, and outcomes are reported transparently.
Publishing Standards and Practices
Caleo is a publishing services provider, not a journal owner. Each journal we serve is owned and editorially governed by its respective society or institution. Caleo provides the operational, technical, and strategic infrastructure that supports these journals. Journal-specific editorial policies, including scope, peer-review criteria, and acceptance decisions, are determined by each journal's editors and editorial board.

Caleo partners with academic societies and institutions to provide publishing services for their scholarly journals. Our team brings over fifteen years of experience working with more than 150 journals, from small society titles to high-impact international publications.
We manage submission workflows, coordinate peer review logistics, oversee production and typesetting, maintain journal platforms, manage indexing applications and metadata, and support communications and outreach.
In every case, the editorial authority rests with the journal's editor-in-chief, editorial board, and owning organisation. Decisions on what to publish, peer-review standards, and editorial direction are theirs alone.
We operate under formal agreements with each journal owner that define the scope of services, responsibilities, and governance. Caleo acts on behalf of these organisations, not in place of them.
-
Caleo supports its partner journals in developing, maintaining, and publishing clear editorial policies aligned with international best practices. Each journal's editorial policies are set by its editors and owning organisation. Caleo provides policy templates, guidance, and regular reviews to help ensure these policies meet the expectations of indexing bodies, funders, and the scholarly community.
The areas we support include:
Scope and aims: Helping journals define and communicate a clear editorial scope so that authors understand what the journal publishes.
Peer-review process: Supporting the design and documentation of transparent, rigorous peer-review workflows, including reviewer selection criteria, timelines, decision categories, and appeals procedures.
Authorship and contributorship: Advising on policies consistent with ICMJE recommendations or CRediT (Contributor Roles Taxonomy) as appropriate to the discipline.
Conflicts of interest: Supporting disclosure requirements for authors, reviewers, and editors.
Corrections, retractions, and expressions of concern: Managing post-publication changes in accordance with COPE guidelines, including maintaining the integrity of the published record.
Complaints and appeals: Helping journals establish documented procedures for handling editorial complaints and author appeals.
Each journal publishes its own editorial policies on its website. Caleo ensures these policies are kept up to date and publicly accessible.
-
Caleo applies systematic integrity screening to all manuscripts processed through its workflows, regardless of journal. Catching problems early protects the journal's reputation and reduces the risk of post-publication corrections.
Pre-publication screening
Every submission undergoes checks for:
Text similarity and plagiarism, using industry-standard detection tools
Image duplication and manipulation
Citation manipulation patterns
Paper-mill indicators and suspicious submission behaviour
Completeness of ethics declarations, including ethics committee approvals, informed consent, clinical trial registration, and data availability statements as applicable
Post-publication integrity
When integrity concerns arise after publication, whether identified internally, reported by readers, or flagged by external bodies, Caleo follows COPE (Committee on Publication Ethics) flowcharts and guidelines to support the journal's editors in investigating and resolving the matter. This includes managing corrections, retractions, and expressions of concern, with full transparency in the published record.
Staff training
Caleo's staff receive ongoing training in research integrity. This covers recognising fabrication, falsification, and plagiarism; handling ethical complaints; and applying COPE guidance in practice.
-
Caleo operates an XML-first production workflow. Accepted manuscripts are structured in JATS (Journal Article Tag Suite) XML, from which all output formats, including the web version, PDF, and machine-readable metadata, are generated.
Our production standards include:
Professional copyediting and typesetting with author proof review
DOI registration via Crossref for all published content
ORCID integration for author identification
Reference linking and verification
Accessibility-conscious web design aligned with WCAG guidelines
Long-term digital preservation through services such as LOCKSS, CLOCKSS, or Portico
-
Caleo supports journals in implementing transparent and sustainable open-access models. Depending on the journal's strategy and the owning organisation's preferences, these may include Diamond open access (no fees to authors or readers), Gold open access with article processing charges (APCs), or hybrid models.
For each journal, Caleo helps establish:
Clear licensing terms, with Creative Commons licences (typically CC BY or CC BY-NC) applied at the article level
Transparent APC schedules and waiver policies, where applicable
Compliance with funder mandates such as Plan S and the NIH Public Access Policy
Copyright policies that are clearly stated and publicly accessible
-
Caleo manages indexing applications and ongoing compliance for the journals it serves. This includes major international indexes such as PubMed/PMC, Web of Science, Scopus, and DOAJ, as well as discipline-specific and regional indexes relevant to each journal.
Our indexing work covers preparing and submitting applications, ensuring metadata feeds meet the technical specifications of each service, monitoring compliance with evolving criteria, and managing renewals and re-evaluations. We maintain clean, structured metadata to maximise discoverability and interoperability.
-
Caleo operates under formal service agreements with each journal owner. These agreements define the scope of services, responsibilities, and financial arrangements. We maintain transparent financial reporting and conduct regular operational reviews with journal editors and society leadership. Caleo has no undisclosed commercial relationships that could influence editorial decisions at any journal we serve.
-
Our practices are aligned with the guidelines and recommendations of:
COPE, Committee on Publication Ethics
ICMJE, International Committee of Medical Journal Editors
DOAJ, Directory of Open Access Journals (best-practice criteria)
EASE, European Association of Science Editors
NISO, National Information Standards Organization (JATS and metadata standards)
