Most of the experiments linked to here are running on R&D equipment in a non-production environment. They may disappear without warning and/or perform erratically. If one of them isn’t working for some reason, come back later and try again.
- CrossRef Metadata Search: Search CrossRef’s fifty million-plus metadata records. Cite search results. Add results to your ORCID profile. Use the API to resolve citations to DOIs automatically.
- InChI Lookup: Show what CrossRef DOIs mention a specific International Chemical Identifier (InChI). See which InChIs are mentioned by a CrossRef DOI.
- OpenSearch Description File: Add CrossRef Metadata Search to your browser’s search bar.
- QR Code Generator: Given a DOI, generate a QR code that includes the basic metadata for that DOI.
- pmid2doi: API to lookup DOI for a PMID or the other way around.
- pdfmark: Open source command line tool to allow you to add CrossRef metadata to a PDF.
- pdfstamp: Open source command line tool to automate the application of linked images to PDFs.
- Family Name Detector: API to determine whether a word is likely to be a family name. Based on all the surnames listed in CrossRef’s 50+ million records. You can also download a list of all the distinct surnames listed in CrossRef metadata.
- Reverse Domain Lookup: API to check if a domain name is likely to belong to a CrossRef member (e.g. a scholarly publisher).
- Citation Formatting Service: API. Given a CrossRef DOI, return a citation formatted to a specified style-sheet (e.g. APA, Chicago, MLA).
- PDF-Extract: Open source command-line too to let you extract references and other metadata from PDFs.
- Randoim: API that will return you X random CrossRef DOIs. Allows sub-selections. Great tool for testing applications that make us of CrossRef DOIs.
- PatentCite: See what patents cite a given CrossRef DOI.
