  • Good morning - I’m very happy to be here today. I’m going to be providing a brief overview of what CrossRef is all about, what we do and what we are planning for the future. Many of you will have heard of CrossRef and DOIs - digital object identifiers. I’ll talk about that and also about some other activities--CrossRef is not just about reference linking anymore.
  • To explain briefly the background of CrossRef’s formation I want to take a look at a set of standard journal article references - crucial component of scholarly communications. preserve the scholarly record - minutes of science. Content going online in 1990s publishers started signing bilateral linking agreements with each other and started using URLs to link to one another. Figure out the publisher, keep track of URL schemes, keep it all up-to-date
  • For scholarly journal publishers have links break is not a good thing because it makes readers unhappy and they complain.
  • When a researcher is looking for high quality scholarly content you don’t want to retrieve the 404 - page not found error. Having this happen undermines trust in the scholarly system and in scholarly publishers.
  • So at the end of 1999 a group of publishers got together and decided to collaborate to solve the problem and CrossRef was set up as a strategic org - CrossRef is a non-profit membership association of publishers with all members being equal. We were founded to provide services to publishers that are best achieved collaboratively - or doing those things that publishers can’t do on their own. We are run by and for publishers and we include all types of publishers. Network!
  • 2700 publishers and societies Almost 20,000 journal titles close to 36 million dois registered.
  • Reference linking includes multiple content types, backfiles
  • uniquely identify/name a piece of electronic content serve as a stable, persistent link to that content’s location on the web A DOI persists throughout changes in copyright ownership or location because it’s just a name used to look up an address in an updateable directory
  • obligations of membership = quid pro quo - level playing field.
  • Registration of content with CrossRef - reference matching and use of DOIs for linking. Hop between different publisher systems.
  • Multiple resolution--the DOI gives the user a choice of which links to follow.
  • backfile content -oldest content from 1665 and the Philosophical Transactions.
  • End user clicks -driving traffic to publisher content each month.
  • The iThenticate software can compare two documents in the same language for similarity, but it cannot yet translate languages to compare them.
  • These are all problems that we’re looking to address by launching CrossMark
  • So CrossMark. At its simplest it’s a logo that publishers will apply to content that they publish. When a reader clicks on the logo they will quickly and easily be able to tell: The best way to explain it is to show some examples.
  • This is the killer example is an important one. This is a PDF that includes the CrossMark logo - a clickable logo. Providing the the user is online, when they click on the logo it will pop up a webpage...
  • with the CrossMark dialogue box giving the latest status. This is an example where CrossMark is at its most useful, alerting the user to the fact that the document they have locally on their machine has updates. This is going to be the most common scenario in which CrossMark really provides the reader with a valuable service, as it’s alerting them to something that they would otherwise most probably have missed.
  • The second example is of a corrected article from another of our pilot publishers, the International Union of Crystallographers. Here, clicking on the logo brings up the same CrossMark dialog box...
  • ..but with information that alerts the reader to changes. Updates are available for this document. It says that there is a correction and gives a link to the correction.
  • You may have noticed in that previous example that there is an additional tab appearing in the dialogue box at the top here - the record tab.
  • This is where you can show additional metadata about the piece of content if you choose to do so. The publisher decides what to put here and can use these fields to define publication practices. You don’t have to populate this tab at all if you prefer not to, and if you don’t supply an additional metadata the tab simply won’t show. The fields are defined and labelled by the publisher, and there can be as many or as few as you choose. This particular data from another of our pilot participants, the International Union of Crystallography, and you can see that they are sharing some really useful information on the copyright, review process and publication history.
  • These are a few of the other possible pieces of information that have come up when talking with publishers. CrossRef isn’t going to advise on what publishers should display in the record box, but we expect that communities of interest may develop guidelines or best practices within different areas. There’s already a group of publishers discussing how best to display funding and grant information, for example.
