The Crossref Curriculum

Querying with formatted citations

Formatted citations are sometimes referred to as plain text references. For example, an APA-formatted citation for the DOI https://doi.org/10.1038/nclimate1398 is:

Hungate, B. A., and Hampton, H. M. (2012). Ecosystem services: Valuing ecosystems for climate. Nature Climate Change, 2(3), 151-152. https://doi.org/10.1038/nclimate1398

Crossref has two interfaces that can be used for making formatted citation queries:

  1. Simple Text Query: a tool which allows a user to cut-and-paste references into an interactive form and receive instant results, or upload a text file and receive HTML format results via email.
  2. XML API: supports XML-formatted queries via HTTPS POST and GET.
