The DOI® Handbook is the primary source of information about the DOI® System.

The DOI name 10.1000/182 identifies the currently applicable latest version of the handbook. Version 5 (first released in April 2012) is substantially re-written compared to earlier versions (though compatible with them), to reflect the approval and publication of ISO 26324: DOI System, in 2012, and now includes relevant ISO terminology.

Compliance with this and subsequent versions of the DOI Handbook will ensure compliance with the ISO 26324 standard. Individual chapters of the handbook will be updated separately; the date of the last update for each chapter is shown in each chapter's heading.

Note that some links in the handbook are to additional material available only to members of the International DOI Foundation.

Comments about the handbook are welcome and should be sent to Dr. Norman Paskin at contact@doi.org.
