All About DOIs

A digital object identifier (DOI) is a unique alphanumeric string assigned to a resource in order to provide a persistent link to its location on the Internet. All DOI numbers begin with a 10 and contain a prefix and a suffix separated by a slash. Provided DOIs should always be included for electronic resources, and the APA Style Blog also recommends that writers include them for print resources, when available.
