The plugin add a shortcode in order to link a paper using its doi code. You can also use an other shortcode to resolve doi code and publish a full citation apa formatted. It is also a shortcode for manual citations.
<h3>Link doi</h3>
Using the standard for doi link, the plugin introduce a shortcode in order to create a link to a paper provided by doi. 
How to use the shortcode:
[ctdoi code=”…”]Title of the paper[/doi]
<h3>Doi resolver</h3>
The plugin send the doi code to <a href="https://search.crossref.org/" rel="nofollow ugc">Crossref Metadata Search</a>, get the information and publish a full citation in apa standard with the shortcode [ctdoiresolve …]. 
How to use the shortcode:
[ctdoiresolve code=”…”]
There are also three optional parameters:
[ctdoiresolve code=”…” arxiv=”…”]
if the paper has an arXiv version
[ctdoiresolve code=”…” pdfurl=”…”]
if the paper has a free pdf version
[ctdoiresolve code=”…” archiveurl=”…”]
if the paper has a free version on <a href="https://archive.org/" rel="nofollow ugc">archive.org</a>
<h3>Manual citations</h3>
There’s also a shortcode for manual citations, [paperdata …]. You can use it with the following syntax:
[paperdata auth=”author/s name/s” year=”…” title=”…” journal=”…” vol=”…” issue=”…” pages=”…” code=”…”]
You can also use the arxiv, pdfurl, archiveurl parameters.
<h3>Styling</h3>
You can style citations adding in your css theme the class “paperdata”.
<h3>External service</h3>
Digital Object Identifier, or DOI, is a persistent identifier used to uniquely identify objects, standardized by the International Organization for Standardization (ISO). DOIs are mainly used to identify academic, professional, and government information, such as journal articles, research reports and data sets, official publications.
Citations tools uses the <a href="http://search.crossref.org/help/api" rel="nofollow ugc">CrossRef Metadata API</a> to retrieve complete publication information using the doi code as a search query. CrossRef is a part of the <a href="https://dx.doi.org/" rel="nofollow ugc">doi system</a>.

Named for Jorge Luis Borges (1899–1986), the Argentine writer and librarian known for stories about infinite libraries, imaginary books, and labyrinths of knowledge, Borges Bibliography Builder brings order to scholarly references in WordPress.
The Borges Bibliography Builder transforms pasted DOI(s), PubMed/PMID records, BibTeX entries, and citations into a semantically rich, auto-sorted reference list.
One-click import. Paste a DOI and CrossRef resolves the metadata instantly. Paste a PubMed/PMID identifier and Borges resolves it through an authenticated WordPress REST proxy to NCBI/PMC citation metadata. Paste BibTeX or formatted citations for books, articles, chapters, webpages, reviews, and theses.
Nine citation styles. Choose from Chicago Notes-Bibliography, Chicago Author-Date, APA 7, MLA 9, Harvard, Vancouver, IEEE, OSCOLA, and ABNT (Associação Brasileira de Normas Técnicas / NBR 6023:2018) — all with automatic sorting per style rules.
Portable. Static HTML output survives plugin deactivation. No shortcodes. No database tables.
Reference-manager friendly. Export and reuse your bibliography in common research workflows. Borges supports CSL-JSON, BibTeX, BibLaTeX, RIS, DOI links, JSON-LD, and optional COinS metadata for compatibility with tools such as Zotero, Mendeley, EndNote, JabRef, BibDesk, and other citation managers.
Try it first. Launch a disposable demo in <a href="https://playground.wordpress.net/?blueprint-url=https://raw.githubusercontent.com/dknauss/borges-bibliography-builder/main/playground/blueprint.json" rel="nofollow ugc">WordPress Playground</a> before installing it on your site.
Translation-ready. Plugin interface strings use the <code>borges-bibliography-builder</code> text domain, and official WordPress.org language packs are generated as community translations are approved on translate.wordpress.org.
<h3>Known Limitations</h3>
OSCOLA grouped bibliography — OSCOLA convention requires the bibliography to be divided into source-type groups (cases, legislation, books, articles, online sources). Borges currently renders a single alphabetized list regardless of style. A dismissible notice in the editor explains this when OSCOLA is selected. Grouped-bibliography support is planned for a future release.
<h3>Development</h3>
Full developer documentation, source code, issue tracker, and contribution guidelines are on GitHub:
<a href="https://github.com/dknauss/borges-bibliography-builder" rel="nofollow ugc">https://github.com/dknauss/borges-bibliography-builder</a>
Bug reports, feature requests, and pull requests are welcome. See CONTRIBUTING.md in the repository for development setup, coding standards, and the PR process.
<h3>External Services</h3>
This plugin connects to fixed scholarly metadata services only when you explicitly add an identifier in the block editor — no citation data is sent automatically or in the background. No account or API key is required for the supported DOI or PMID lookups.
DOI metadata
DOI input connects to the CrossRef REST API (https://api.crossref.org/) to resolve citation metadata.
<ul>
<li>CrossRef service: https://www.crossref.org/</li>
<li>CrossRef REST API documentation: https://api.crossref.org/swagger-ui/index.html</li>
<li>CrossRef privacy policy: https://www.crossref.org/privacy/</li>
<li>CrossRef terms of service: https://www.crossref.org/terms/</li>
</ul>
PubMed/PMID metadata
PubMed/PMID input connects through the plugin’s authenticated WordPress REST proxy to the NCBI/PMC Literature Citation Exporter CSL endpoint. The proxy uses a fixed upstream host and validates the PMID before making the outbound request.
<ul>
<li>NCBI APIs: https://www.ncbi.nlm.nih.gov/home/develop/api/</li>
<li>NCBI/PMC Literature Citation Exporter: https://pmc.ncbi.nlm.nih.gov/api/ctxp/</li>
<li>NLM Web Policies: https://www.nlm.nih.gov/web_policies.html</li>
</ul>
