Indexing and Discoverability
What carries an article from this journal out into the wider literature, service by service — and what each of those services actually is, since registering an identifier, harvesting metadata, being listed in a database and being preserved are four different things.

Four different things, often given one name
“Indexed” is used loosely enough to cover services that do quite different work. Registering an identifier makes an article citable. Registering a DOI makes the link to it permanent. Harvesting exposes its metadata to anyone who wants it. Selective indexing means a database has assessed the journal and chosen to list it. Preservation means the article survives the publisher.
Each entry below names which of those a service performs for this journal, so that the categories stay apart. A service is listed only where the journal’s status in it can be checked, and an official link is given wherever one exists to check it against.
The services
What is in place, and what each one does
Journal identifier
ISSN
The International Standard Serial Number identifies this journal in catalogs, library systems and citation records. It is what distinguishes the journal from any other title with a similar name, and it is the key most other services use to refer to it.
ISSN 2326-0793
Journal identifier
NLM Catalog
The United States National Library of Medicine holds a catalog record for the journal, which is where its standard abbreviation comes from. A catalog record is a description of the title; it is separate from selection for MEDLINE, which is covered further down this page.
NLM Catalog 101626993 · abbreviation: J Proteom Genom Res
DOI registration
Crossref
Articles are assigned a Digital Object Identifier and registered with Crossref, along with their metadata: authors, title, journal, volume, issue, pages, publication date and reference list. The DOI is the permanent link to the article and the form in which other publishers’ reference lists point at it. Registering a DOI is metadata registration rather than indexing; it says nothing about any database having selected the journal.
Prefix 10.14302 · DOIs take the form 10.14302/issn.2326-0793.jpgr-00-0000
Metadata harvesting
OAI-PMH
The publisher exposes an Open Archives Initiative Protocol for Metadata Harvesting endpoint in Dublin Core. Any repository, aggregator or discovery service may harvest the journal’s records from it without asking. Harvesting makes the metadata available to a service; whether a given service chooses to take it is the service’s decision.

Discovery service
OpenAlex
OpenAlex holds a source record for the journal under its ISSN and carries its articles, their authors and their citation links. A discovery service gathers and connects published work at scale; unlike a selective index, it does not assess a journal before including it.

Digital preservation
Portico
This journal’s content is committed to Portico, a not-for-profit digital-preservation archive run by ITHAKA (the organization behind JSTOR). As articles are deposited they enter Portico’s permanent archive, so the scholarly record stays available for the long term — even if a title one day ceases to publish.
The publisher’s Portico record is at portico.org/publishers/openap.
Selective indexing
Journal-level indexing status
Selective indexing is the category where a database assesses a journal and decides whether to list it. It is the one category on this page that depends on another organization’s decision rather than on the publisher’s own infrastructure, so the journal’s position is stated here from the authoritative record rather than summarized.
The National Library of Medicine’s catalog record for this journal gives its current MEDLINE indexing status as N, meaning the journal is not currently selected for MEDLINE. The catalog record itself remains available at the link above.
Confirmed journal-level listings are named on this page as they are confirmed, each with the record a reader can open to check it.
Status last checked 13 September 2026.
Article-level deposit
Individual articles in PubMed Central
An individual article can reach PubMed Central through a funder deposit route that belongs to the article and its authors rather than to the journal. Finding an article from this journal in PubMed therefore reflects that deposit, and is a separate matter from the journal-level indexing status above.
Eligible NIH-funded manuscripts may be deposited individually in PubMed Central through the NIH Manuscript Submission System (NIHMS).
Authors whose funder requires deposit should tell the editorial office when the manuscript is accepted, and the Instructions for Authors describe what is needed.
Where to look
Checking a record
Each service above links to the record a reader can open. Where an institution or funder needs written confirmation of an article’s status for its own reporting, the editorial office can supply it.
