The Simple Text Query allows users to retrieve DOI names for journal articles, books, and chapters by cutting and pasting a reference or reference list into the query box. References are input as a standard bibliographic entry, such as:
Clow GD, McKay CP, Simmons Jr. GM, and Wharton RA, Jr. 1988. Climatological observations and predicted sublimation rates at Lake Hoare, Antarctica. Journal of Climate 1:715-728.
For best results, each reference should appear on a single line. When submitting multiple references, enter them in alphabetical order or as a numbered list. Separate individual references using a blank line.
- Register for access using a verifiable email address.
- Go to the Simple Text Query form and enter a reference or list of references into the search box. Enter your email address where indicated
- select 'List all possible DOIs per reference*' to return multiple results
- select 'Include PubMed IDs in results' to include PubMed IDs
This service is currently being offered free of charge to the public and has a capacity limitation of a couple dozen references per submittal. The Simple Text Query is not an appropriate tool for high volume operations and queries are limited to 1,000 per month. This limit is intended to be a limit on an individual, or the organization represented by an individual.
For publishers participating in cited-by linking, the SimpleText Query form may also be used to deposit references.
Crossref attempts to find exactly one DOI for each reference. For some citations, multiple DOIs may be deposited for an item, or the metadata in either the reference or record registered with Crossref is not sufficient to make a single match. Selecting List All Possible DOIs will return multiple results which will need to be evaluated to select the appropriate DOI.
