Standardized Issue Schedule

The standardized annual schedule beginning with Volume 5 (2027) is No. 1 January–April, No. 2 May–August, and No. 3 September–December. These periods identify the journal's three regular issues within each calendar-year volume. ABIM does not publish a fourth regular issue under this model.

The schedule applies prospectively and does not redefine the original issue titles, issue-level publication dates, article assignments, or bibliographic records of earlier volumes.

PERLU VERIFIKASI: The journal website and supplied policy establish ABIM's stated publication schedule. They do not independently establish its alignment with the frequency recorded by the responsible ISSN authority or prove any required notification or approval of a frequency change. The relevant ISSN frequency information and any applicable correspondence remain to be verified.

2026–2027 Transition

The standardized January–April, May–August, and September–December calendar applies beginning with Volume 5 (2027). Published issues of Volume 4 (2026) remain part of the permanent historical record with their original issue numbers and recorded issue-level publication dates: No. 1 — 31 January 2026, No. 2 — 14 April 2026, and No. 3 — 26 July 2026. Valid DOI records and other bibliographic metadata are not retrospectively altered.

October–December 2026 forms part of the transition to the standardized calendar. The journal may continue submission handling, screening, peer review, revisions, final decisions, post-acceptance administration, copyediting, production preparation, and metadata verification. This transitional arrangement does not establish a fourth numbered issue in Volume 4.

Any article formally released during the transition must have a valid volume and numbered-issue assignment under the applicable arrangements. Articles intended for the 2027 cycle may be prepared for release beginning with Volume 5, No. 1 in January 2027 after completing all required stages. Publication dates must not be artificially backdated or otherwise altered to accommodate the transition.

Issue-level publication dates do not necessarily represent the publication date of every article within an issue. Article dates and assignments must be interpreted through the applicable authoritative article records.

Continuous Publication

Beginning prospectively on 1 September 2026, ABIM applies continuous publication within the applicable active numbered issue. A publication-ready article may be released after final scientific-editorial acceptance, applicable APC or waiver verification, post-acceptance administration, copyediting, proofreading and production, metadata verification, and preparation of the Version of Record. It does not need to wait until every other manuscript assigned to the same issue has completed production.

Continuous publication changes the timing of article release within the active issue. It does not alter the annual volume structure, create an additional regular issue, or weaken double-anonymous peer review, independent editorial decisions, research integrity, or publication-quality requirements. The 2026–2027 transition remains applicable.

APC payment and waiver administration begin only after final scientific-editorial acceptance. Payment or waiver status does not determine scientific acceptance or independently guarantee a publication date, issue assignment, or production priority.

Version of Record & Publication Metadata

The final article formally published on the ABIM website constitutes the journal's authoritative Version of Record. For articles released through continuous publication, the publication date represents the actual date on which the Version of Record is formally made available online.

Volume, issue, publication date, DOI, title, author information, licensing, pagination or article identifiers where applicable, and other essential metadata should remain consistent across the website, published article, DOI record, and relevant scholarly services. The beginning or end of an issue period must not replace an article's actual publication date unless the dates genuinely coincide.

Genuine metadata errors may be corrected through appropriate editorial and technical procedures while preserving the accuracy and traceability of the scholarly record.

Historical Scholarly Record

Previously published volumes, issues, articles, publication dates, pagination, article identifiers, DOI records, issue titles, authorship, and other valid bibliographic information remain part of ABIM's permanent scholarly record. The current model does not authorize retrospective renumbering, re-dating, relabeling, redistribution of published articles, or reconstruction of earlier content merely to match a later schedule.

The archive records the following earlier issue-level dates: Volume 1 (2023) — No. 1, 26 January; No. 2, 31 May; No. 3, 30 September. Volume 2 (2024) — No. 1, 31 January; No. 2, 31 May; No. 3, 30 August. Volume 3 (2025) — No. 1, 31 January; No. 2, 31 May; No. 3, 30 September. These historical records are not replaced by the standardized 2027 issue periods.

Established issue titles and historical publication periods remain unchanged unless a genuine error is supported by evidence and corrected transparently. Administrative standardization alone is not evidence of a metadata error.

Journal Archives

ABIM maintains an online archive of its published volumes, issues, and articles. Readers should cite the bibliographic information and DOI associated with the applicable Version of Record.

PERLU VERIFIKASI — Current Issue display: During checking, the archive and individual issue pages were accessible, while the Current Issue endpoint returned a conflicting no-issues message. This does not establish that published issues are absent. The current-issue assignment and public display require technical verification without changing valid historical publication records.
