With the emergence of the Internet, articles became clickable as URLs were used to link and cite work. But there were two problems. First publishers had to sign hundreds of individual linking agreements with each other\u2014which would have become overwhelming; and second, some URLs began to fail, mainly due to content being moved or URL schemes changing, and could no longer be relied upon.<\/p>\n

Enter the Digital Object Identifier (DOI). Unlike a URL, a DOI is a persistent identifier\u2014a life-long reference\u2014that sticks to the content <\/em>of an online object, not the location<\/em>, therefore remaining associated with the work, irrespective of changes to work’s web address. The DOI is<\/em> associated with a URL, but this can be updated centrally, so it always redirects to the current location of the content.<\/p>\n

That central updating happens through Crossref. In the year 2000, Crossref was founded by a group of forward-thinking scholarly publishers who understood the need to provide a collaborative, central reference linking service\u2014using DOIs\u2014which would be accessible to, and governed by, the global scholarly communications community.<\/p>\n

Over the years Crossref has evolved and our mission is now broader than just DOIs and Reference Linking. Today, we are a self-sustaining not-for-profit that aims to make all research outputs easy not just to find, cite, and link, but also to assess and reuse. As publishing has evolved beyond just publishers, to encompass libraries, scholars, funders, and more, so has our 10,000+ member base. These organizations continue to guide us through working groups, committees, a broad range of collaborations and thousands of other metadata users.<\/p>\n

This introductory blog is the first in a series of five posts from Crossref; over the next few months we\u2019ll be talking to them more in depth about the role of the DOI, particularly in terms of<\/p>\n
