Build bibliography entries from publication identifiers

DOI to BibTeX retrieves publication metadata for each DOI and turns the returned fields into a structured bibliography entry. Paste one DOI or doi.org link per line. This is useful when a reading list contains identifiers but your LaTeX project needs authors, titles and publication details in a .bib database. A DOI identifies a record; it does not itself contain all the bibliographic fields, so provider availability and metadata completeness affect the result.

Keep DOI selected as From and BibTeX as To, then convert the batch. Inspect the successful records and any per-line failures before downloading. If one identifier fails, preserve the successful output and investigate that identifier separately. A malformed DOI, a missing database record and a temporary provider failure are different problems and should not all be treated as evidence that the cited paper is invalid.

Worked example: an identifier becomes a book entry

The DOI 10.1037/0000168-000 identifies L. M. Jackson’s The psychology of prejudice: From attitudes to social action, second edition, published in 2019 by the American Psychological Association. The example shows the core fields expected from that known bibliographic record. It is an annotated mapping, not a fresh provider response or a promise about field order, generated citation keys or optional metadata in a future download.

The entry type is book because the identified object is a book. The DOI remains in its own field, the edition is separate from the title and the year is the publication year. Compare these fields with the source. If a provider returns an article for a DOI you thought belonged to a book chapter, resolve the identity before editing the type simply to fit your expectations.

Review author parsing, capitalization and missing fields

Provider creators become the author list, publication dates supply year information and the source type determines a suitable BibTeX entry type. Container titles, volume, issue, pages, publisher and DOI are included where supported and available. Keep author order as published. A provider’s unstructured name can be ambiguous, so check compound surnames and corporate authors in the exported file instead of assuming that syntactically valid BibTeX guarantees correct attribution.

The bibliography style in your LaTeX project controls the final capitalization and display. Review proper names, acronyms and mathematical notation after rendering. A missing issue or page range may reflect incomplete metadata rather than a conversion bug; an article number may legitimately replace conventional pages. Look at the publication before supplying a value. This tool does not infer missing fields from full text or use AI to complete a record.

When to use BibTeX rather than a formatted reference

Choose BibTeX when you need reusable structured records and citation keys for LaTeX or a compatible editor. Choose DOI to APA for a readable APA 7 reference list, or RIS when moving records into a reference manager that expects that format. Download the .bib file before leaving, review duplicate keys when combining files and compile a small sample. A successful download does not establish that the destination manuscript uses those entries correctly.

Conversion limits and processing

  • The first 10 references are free per browser, shared across all six converter pages. Files: up to 1 MB; batches: up to 100 references.
  • File formats are parsed in your browser. Identifier lookups go through the server to Crossref / DataCite (DOI), NCBI PubMed (PMID), Open Library (ISBN) or arXiv. No AI is used to convert references.
  • Review any field-loss warnings and keep your original file. Attachments and custom library fields are not a complete portable backup.

Frequently asked questions

Should I paste a DOI or a URL?

Either a bare DOI or its doi.org URL is accepted, one per line. Copy the identifier carefully from the publication. Do not substitute a publisher homepage, search-results link or arbitrary article URL for the DOI in this input mode.

What does DOI to BibTeX return?

It returns structured bibliography entries using the metadata retrieved for your identifiers. Entry keys and field order can differ from the illustration. The output is intended for a .bib file; it does not contain a paper’s full text or evidence supporting your claims.

Can I convert several DOIs for free?

Yes. The first 10 references are free across all converter pages in this browser, with up to 100 references in a batch. Review partial failures separately. Downloading or copying the completed output does not use another reference allowance.

Where does the metadata come from?

DOIs are looked up through Crossref, with DataCite used when Crossref has no record. A temporary Crossref failure is not the same as an absent record. Check returned fields against the publication; the converter does not generate metadata with AI.

Why was one DOI rejected?

Check for extra punctuation, an incomplete suffix or an identifier copied from the wrong source. If the provider is unavailable, retry later. Keep the successful entries and inspect the failed line instead of replacing it with a guessed title-based match.

Does it preserve every publication field?

Only supported, available metadata can be mapped. Missing author details, unusual source types and title markup require review, and full text or attachments are not included. Preserve the DOI and check the rendered reference after your LaTeX style applies its formatting.

How do I add the output to Overleaf?

Download or copy the BibTeX into the bibliography file used by your project. Check keys for duplicates and use those keys in your manuscript’s citation commands. This page does not connect to or transfer the bibliography into an Overleaf project.
