CrossRef, a non-profit membership association founded and directed by publishers, announced that BSI British Standards has joined as a new CrossRef member. As a member, subject to the creation of an appropriate protocol, BSI will be able to register standards with CrossRef and implement interlinking with other scholarly and scientific publications. This will be achieved through use of the DOI (Digital Object Identifier) System for which CrossRef provides content registration services. CrossRef includes hundreds of publishers and societies, with 28.9 million content items registered to date. BSI British Standards has 27,000 current standards. CrossRef and BSI British Standards will join forces to establish a working group of interested parties, made up of both CrossRef members and outside organizations, to discuss best practice for assigning DOI names to standards.
