  title: CMU Library Publishing Service Journals API
  version: '1.0'
  description: 'Read API for the Carnegie Mellon University Library Publishing Service, the open-access scholarly publishing programme run by CMU University Libraries. It exposes the five journals CMU publishes — Language Development Research (ISSN 2771-7976), Encyclopedia of the History of Science (2642-5890), MAJAL: CMUQ''s Undergraduate Journal, Negotiation and Conflict Management Research (1750-4716) and Tolstoy Studies Journal — along with their issues, articles (379 when probed), keywords, licences and preprint repository objects, plus a full OAI-PMH 2.0 provider. This is the surface the June 2026 profile missed entirely while crediting CMU with figshare''s contract: it is self-hosted on lps.library.cmu.edu at 128.2.24.32, inside Carnegie Mellon''s own /16, and its OAI-PMH Identify response names Carnegie Mellon University Library Publishing Service as the repository and librarypublishing@andrew.cmu.edu as the administrator.'

  x-operator-evidence: 'lps.library.cmu.edu is under Carnegie Mellon University''s own registrable domain and resolves to 128.2.24.32 — Carnegie Mellon''s own 128.2.0.0/16 address space, not a vendor CDN or cloud tenancy. Contrast kilthub.cmu.edu, which is a CNAME to FIGSHARE.COM and is therefore recorded as `tenant`, and canvas.cmu.edu, which is a CNAME to CMU-VANITY.INSTRUCTURE.COM. The software is Janeway, an open-source publishing platform, but CMU operates the instance: the OAI-PMH Identify response returns repositoryName "Carnegie Mellon University Library Publishing Service" and adminEmail librarypublishing@andrew.cmu.edu, and every journal record carries publisher "Carnegie Mellon University Library Publishing Service".

    source: Live probes of https://lps.library.cmu.edu/api/ and https://ncmr.lps.library.cmu.edu/api/oai/ on 2026-08-19. The API is a Django REST Framework browsable root that self-describes its collections; every path below was read from that root and confirmed by request.
    authorship: Written by API Evangelist, not published by Carnegie Mellon University. No OpenAPI, schema endpoint or API documentation page is served for this surface.
    coverage: The DRF root advertises eighteen collections (accountrole, journals, issues, articles, licences, keywords, accounts, preprints, repository_licenses, repository_fields, preprint_files, user_preprints, repository_subjects, published_preprints, version_queue, identifiers, user_info, logout). The four public read collections that were probed and returned real data are modelled here; the account- and workflow-scoped collections are listed in x-unmodelled-collections rather than guessed at.

  - repository_licenses
  - repository_fields
