  • After you’ve retrieved your reference DOIs, you need to include them in the reference lists on your website. The DOI links can be represented in a few different ways, here’s one example – the ‘Article’ links are DOI links.

Introduction to CrossRef Webinar Introduction to CrossRef Webinar Presentation Transcript

  • Introduction to CrossRef Patricia Feeney Product Support Manager May 21, 2014
  • Why do publishers join?  To get persistent identifiers for their content  To drive more traffic to their content  To turn references into hyperlinks  To pull in cited-by links (who cites this?)  Participate in other collaborative services (CrossCheck, CrossMark)
  • DOI = Digital Object Identifier  Uniquely identifies a digital object  Solves link rot (broken links)
  • + DOI = persistent URL 9

  • International DOI Foundation (IDF): oversees the central DOI system, promote DOI as a standard, and provides an organizational infrastructure that ensures persistence and interoperability. Corporation for National Research Initiatives (CNRI): they (among other things) are responsible for the Handle system, which is the technology that causes DOIs to resolve. Registration Agencies (RAs): Register DOIs on behalf of other organizations. CrossRef is a RA.
  • Registration agencies European Union Office of Publications TIB (Technische Informationsbibliotek) R.R. Bowker Nielsen Bookdata Copyright Agency Limited (CAL) mEDRA Wanfang Data DataCite
  • Broken links are a problem
  • Deposit DOIs and metadata Basic citation metadata: author (s), journal title, article title, volume, issue, publication date, book title, chapter title, page numbers, article IDs, internal identifiers, ISSN, ISBN… Optional (but recommended): Funding information, ORCIDs, references (to support cited- by linking), CrossMark metadata
  • Prefix:  Assigned to members  Format is 10.XXXX (or 10.XXXXX)  Identifies who initially created the DOI  Prefix does not identify the current owner of the DOI Suffix:  Unique within a prefix – a DOI can only be assigned to one item  Consistent  Logical  Easily documented  Readily implemented  case insensitive DOI directory 10.1006/ DOI prefix jmbi.1995.0238 DOI suffix

  • DOI match! DOI match!
  • Resolve all conflicts Conflicts occur when two (or more) DOIs share the same metadata, suggesting two DOIs are assigned to a single item.
  • Why are conflicts bad?  Only one DOI should be assigned per item  Queries will return multiple DOIs, causing confusion  Some queries (OpenURL) may not return a DOI if multiple results are present  Conflicts between two DOIs often result in one of the DOIs being neglected
  • Conflict reports (in Members Area)
  • Update metadata and URLs URL update;fromPrefix=10.5555;toPrefix=10.5555 10.5555/doi1 10.5555/doi2 10.5555/doi2
  • Maintaining Journal Titles  Title and ISSN combinations are determined by the publisher.  A valid ISSN is required for all journal titles  The title / ISSN combination in your deposit must match the title / ISSN combination in our system.  If a title changes, a new ISSN is required  Journals should be deposited under the original title Title list: Title transfer policies:
  • Recurring reports:  Resolution Report (email) As-needed reports:  Conflict  DOI Error Report (email)  Schematron Report (email) Always available:  Depositor Report  Status Report  Go-live report  Title list Tools  XML Parser  Test system:  Deposit Harvester Reports!
  • Resolution Report (emailed monthly)
  •  compiled from reports submitted by end users  emailed nightly to technical contact DOI Error report (emailed nightly as needed) Reasons for DOI Error:  a DOI has been published but not deposited  the published DOI does not match the deposited DOI  the end user misinterpreted or mistyped a DOI (i.e. confusing 1 for l or 0 for O)
  • Make plans for long-term archiving CLOCKSS: Koninklijke Bibliotheek / National Library of the Netherlands: Portico:
  • Pay bills and keep in touch Billing:  Annual membership feel billed annually, sent out in December  Deposit fees billed quarterly* ** unless deposit fee total < $1,000, then sent out annually Keep in touch! Send any contact changes to
  • Where to find help:  Help documentation:  CrossRef support: email or visit  Webinars: Staying up to date:  Announcements forum: subscribe via RSS or email  CrossRef Quarterly: CrossRef newsletter  CrossRef Labs: new and experimental tools and initiatives
