Crossref currently provides a number of ways for you to locate a DOI.

• If you have bibliographic data for a item and would like to find the DOI, please use the metadata section of this form.
• If you only have an article title and author, please use the article title search section of this form.
• If you have the text of a bibliographic reference, please use our Simple Text Query service.
• If you are a developer and wish to submit a raw XML query use the XML form section of this page.

This form is a guest query interface to the Crossref system for individual DOI retrieval. This interface is not intended for automated querying. If you would like to query Crossref on an automated batch basis, please obtain an account on our system.

You must supply either author or first page and we recommend using journal title as well as ISSN. For a list of journal titles in the Crossref holdings please visit our browsable journal list.

If you only know the title of an item (article, book chapter, report, working-paper ... etc.) and the author submit them here. This form is a guest query interface to the Crossref system for individual DOI retrieval. This interface is not intended for automated querying. If you would like to query Crossref on an automated batch basis, please obtain an account on our system.

You may enter a query in XML form if you know the tags and wish to experiment with the query control attributes.
