ABC2 Receives DOI-Permanent Digital Identifiers Registration

ABC2 Receives DOI Registration: Permanent Digital Identifiers for All Published Articles

We are pleased to announce that ABC2: Journal of Architecture, Building, Construction, and Cities has been granted DOI (Digital Object Identifier) registration through Crossref. This is an important milestone in the journal's development, demonstrating ABC2's commitment to international standards of scholarly publishing, discoverability, and long-term accessibility. Each ABC2 article is assigned a DOI following a clear and consistent structure like this: https://doi.org/10.66408/abc2.YYYY.ID

The DOI is composed of three elements following the prefix. The registrant code 10.66408 is the unique prefix assigned to ABC2 by Crossref, identifying the journal as the registrant. This is followed by abc2, the journal's abbreviated identifier. Next, YYYY denotes the publication year of the volume in which the article appears (e.g., 2025 or 2026.or later). Finally, the ID is a unique article identifier drawn from the journal's manuscript management system, ensuring that each article carries a distinct and traceable number from submission through to publication.

Retrospective and Ongoing Assignment: All articles published in ABC2 since its inaugural issue in December 2025 have been retrospectively assigned their individual DOIs. This means that every contribution across all four published issues, from Volume 2025, Issue 1 through to the current Volume 2026, Issue 2, now carries a permanent, resolvable identifier. Authors who have already published with ABC2 will find their DOIs active and linked to their respective article pages on the journal website. We are currently in the process of updating the PDF version of all published papers. Going forward, every new article published in ABC2 will receive its DOI upon publication, further supporting citability, cross-referencing, and integration with global scholarly infrastructure.

This reflects ABC2's ongoing progress toward establishing itself as a leading international platform for integrated, transdisciplinary research in architecture, building, construction, and cities. We thank our authors, reviewers, and editorial board members for their continued support in building a rigorous and globally connected journal.
