This webinar is an introduction to CrossRef for publishers and a brief outline of how CrossRef works.

1. Introduction to
CrossRef
for publishers
Patricia Feeney
Product Support Manager

2. Agenda
 CrossRef overview
 Creating and working with CrossRef DOIs
 Maintaining your DOIs and metadata
 CrossRef services
 Resources

3. mission statement:
CrossRef's goal is to be a trusted collaborative organization
with broad community connections; authoritative and
innovative in support of a persistent, sustainable
infrastructure for scholarly communication.

4. 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)

5. DOI = Digital Object Identifier
 Uniquely identifies a digital object
 Solves link rot (broken links)

6. http://dx.doi.org/ + DOI = persistent URL
http://dx.doi.org/10.1155/2013/727539

7. International DOI Foundation (IDF):
oversees the central DOI system, promotes
the 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.

8. DOI Registration agencies
European Union Office of
Publications
TIB (Technische
Informationsbibliotek)
R.R. Bowker
Nielsen Bookdata
Copyright Agency Limited (CAL)
mEDRA
Wanfang Data
DataCite
CrossRef

9. Outbound linking

10. Content beyond journals…
 Books
 Standards
 Proceedings
 Images
 Figures
 Datasets
 Workingpapers
 Dissertations

6% 2%
Journals

(as of 2/12/13)

11. CrossRef 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…

12. Step-by-step
1. Join CrossRef!
2. Publish
3. Deposit
4. Query
5. Outbound linking
6. Maintain DOIs and Metadata

14. Member obligations:
 outbound reference linking
 deposit all current journal articles
 resolve any DOI conflicts
 update metadata and URLs
 do not publicize CrossRef DOIs until links are
live
 pay deposit and annual fees
 make plans for long term archiving

15. Long term archiving:
CLOCKSS: http://clockss.org
Koninklijke Bibliotheek / National Library of the Netherlands:
http://www.kb.nl/
Portico: http://www.portico.org

16. 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

18. Response page must include:
 bibliographic information about the item
 means to access full text
 the DOI

19. DOIs are required on the response page, recommended on other
pages:
 Tables of contents
 Abstracts
 Full text HTML and PDF articles and other scholarly
documents
 Citation downloads to reference management systems
 Metadata feeds to third parties
 “How to Cite This” instructions on content pages
 Social networking links
 Anywhere users are directed to a permanent, stable, or
persistent link to content.

Maintaining DOIs and Metadata

37. 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: http://www.crossref.org/titleList/

38. 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:
http://test.crossref.org
 Deposit Harvester
Maintaining DOIs and Metadata: Reports and
Tools

39. Resolution Report (emailed monthly)

40.  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)

41. Other reports (in Members Area)
Depositor Report: lists all DOIs for a title: Journals, Books, Conference
Proceedings
Conflict report: lists all conflicts by publisher / title (more info)
XML Journal list: XML- formatted list of all CrossRef journal titles
Browsable title list: look up journal, book, and conference proceeding
titles and coverage
