This service is unusual in that it tries to find a non-paywalled version of a title and redirects the user to that instead of the publisher's version.[29][30] Since then, other open-access favoring DOI resolvers have been created, notably https://oadoi.org/ in October 2016[31] (later Unpaywall). The DOI system is an international standard developed by the International Organization for Standardization in its technical committee on identification and description, TC46/SC9.[35] The Draft International Standard ISO/DIS 26324, Information and documentation – Digital Object Identifier System met the ISO requirements for approval.
