This document discusses DOIs (Digital Object Identifiers) and CrossRef's role in registering DOIs for book publishers. It provides an overview of DOIs and the International DOI Foundation (IDF) which oversees the DOI system. CrossRef is introduced as the largest DOI registration agency. The benefits of assigning CrossRef DOIs to books are described, including persistent linking between books and other scholarly content. Best practices for registering book DOIs at CrossRef are outlined, covering metadata requirements, linking, and displaying DOIs in citations.

2. Today’s Agenda
• What are DOIs?
• IDF, Registration Agencies, and CrossRef
• Best Practices for CrossRef book DOIs
• Linking to and from books
• Assigning CrossRef DOIs to books
• Finding book DOIs
• ISSNs and ISBNs for books & series
• What’s next?
3. What is a DOI?
Digital
Object
Identifier
Source: pasukaru76 from Flickr
14. It is a digital identifier of a
digital or physical object
15. It serves as a stable link to
content’s digital location
16. Some DOIs are not CrossRef DOIs
• Other Registration Agencies have assigned
DOIs to books for supply chain purposes, i.e.
the ISBN-A (assigned by mEDRA)
• More information is available here:
http://www.crossref.org/06members/otherdoifaq.html
17. So, what is the relationship between
an RA and the IDF?

Handle system upon which
the DOI executes
CrossRef/DOI Community
23. What Does CrossRef Do?
• Provides technology infrastructure for
linking
Registers DOIs with the Handle System
Provides discoverability services for those DOIs
• Provides business infrastructure for linking
One agreement with CrossRef is a linking agreement
with all CrossRef publishers

26. Why do publishers join
CrossRef?
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?) to get more traffic
Participate in other
collaborative services
(CrossCheck, CrossMark)

30. Why publishers assign CrossRef DOIs to books
• Persistent linking---books interlink with journal articles and
other scholarly content
• Inbound links drive traffic;
• Outbound links add value and utility to readers
• CrossRef Book DOIs can resolve to information on
purchasing -- for both print and online books
• Access/authentication remain under publisher control
31. • Links deliver
reader to front
door
• Access
control up to
publisher or
distributor
is “business-model neutral”

42. Best Practices Book DOIs
http://www.crossref.org/06members/bes
t_practices_for_books.html
43. Best Practices
Assigning, linking and CrossRef DOI use
• Deposit DOIs at the title and chapter/entry level.
• Add outbound links from references in books.
• Deposit references from books with CrossRef to
enable CrossRef Cited-by Linking.
45. Best Practices
Updates and Versions
• Major version – updates affect
interpretation. Publisher notifies readers
that content has changed.
– new editions
– errata
– corrigenda
• Minor version – unlikely to affect
interpretation. No publisher notification.
46. Best Practices
Updates and Versions
• Assign new CrossRef DOIs to new major versions or
editions of books, chapters and entries.
Older versions remain available online with links to the
latest version.
• Do not assign new CrossRef DOIs to minor new versions
of books, chapters and entries.
• Use Multiple Resolution to associate one CrossRef DOI
with multiple URLs, i.e. for electronic formats or multiple
hosting platforms.
47. Notifying readers of new editions
• CrossMark Update

54. What kind of Publication Record
information could be available?
• License types
• Funding disclosures (FundRef)
• Conflict of interest statements
• Publication history (submission, revision and accepted
dates)
• Location of data deposits or registries
• Peer review process used
• CrossCheck plagiarism screening
• and more...
57. Best Practices: Citation Matching
Book Title Queries (finding the DOI)
• Minimum query:
– book title
– book author
– book year
• And as many as possible of these:
– editor (where appropriate)
– publisher
58. Displaying CrossRef DOIs in Book
Citations
• The DOI should appear at the end of the reference
• The DOI should be encoded as a hyperlink
Example:
Corrigan, John. Religion and Emotion - Approaches and Interpretations.
New York: Oxford University Press, 2004. Oxford Scholarship Online.
Oxford University Press. 2005.
http://dx.doi.org/10.1093/0195166248.001.0001
Note: This is a change from the previous format
doi:10.1093/0195166248.001.0001
59. Style Manuals
Provide the DOI, if one has been assigned
to the content….

64. Assigning (depositing) CrossRef Book DOIs
• Deposit metadata and URL(s).
• Metadata required for book DOI registration is
described in the schema, sections 6-8
http://www.crossref.org/schema/deposit/crossref4.3.0.xsd
and in the documentation at:
http://www.crossref.org/schema/info/CrossRefSchemaDocumentation4.1.0.pdf
65. Book Title Level Metadata
• Required data includes:
– Type: edited book, reference, monograph, or other
– Title
– Publisher
– Publication date
– ISBN
• Optional data includes:
– series title, and series ISSN*
– volume and edition numbers
– Book DOI and URL
* If you include a series title it must have an ISSN
66. ISSNs & ISBNs in CrossRef Schema
• ISSNs are assignable to a series title and not book title.
• ISSN is directly bound to series title and must be present in series
• ISSN check digit will be verified upon deposit – invalid ISSNs will be
rejected
• Volume is mandatory if series_metadata is present and volume level
title is NOT present
• Titles and ISSNs/ISBNs in deposit must match titles associated with
ISSNs/ISBNs in the system
• New titles will create a title entry in the system –
updates/additions to this title must remain consistent
• Contact support@crossref.org to change titles
67. Chapter Level Metadata
• Required data includes:
– Chapter title
– DOI and URL
• Optional data:
– Contributors
– Pagination
– Component number
68. • Manual DOI
registration
for books
• System builds
XML deposit
file
Web Deposit Form
http://www.crossref.org/webDeposit/
69. XML deposit
Sample XML is available:
• Monograph:
http://www.crossref.org/schema/info/samples/4.3.0_samples/monograph430.xml
• Series:
http://www.crossref.org/schema/info/samples/4.3.0_samples/book_series430.xml
70. Simple-Text Query
• A freely available, non-XML
alternative for reference linking
• A custom version of Inera’s
eXtyles® refXpress parses
unstructured references into
granular, valid XML and returns
any matching DOIs for those
references
71.
72. How much? CrossRef Deposit Fees for Books
• Current Material
– Titles: $1.00
– Chapters/entries < 250 per title: 25 cents
– Chapters/entries > 250 per title: 15 cents
– Chapters/entries > 10,000 items: 12 cents

• 70 ish Members
• Open to all book publisher members of
CrossRef, and others
• Includes major book hosting platforms
80. Book Interest Group
• Teleconferences several times per year
• Working groups on issues of importance to
book publishers
• 1st in-person meeting in mid-November in
Cambridge, MA at CrossRef Annual Meeting
Once upon a time, the American Association of Publishers, which was instrumental in creating an application of DOIs for reference linking in scholarly publishing, published guidelines that suggested ISBNs be used as the suffix for book DOIs. They withdrew that. CrossRef no longer recommends this practice. We prefer shorter DOIs that readers are not tempted to try to derive. Besides, the proliferation of DOIs for multiple electronic formats means it isn’t clear which ISBN to use. However, the ISO standard suggests using existing identifiers as the suffix so they do not compete with each other. The ISBN working group should look at this issue.
For example, a journal article has the same DOI whether it is printed or available online.
Will accept either the DOI: or the http://dx.doi.org URL format
Many scholarly publishers have digitized their backfiles (back list in book lingo) or are are in the process of doing so. The oldest journal article from 1665 has a CrossRef DOI and is available online.
Could the DOI become a works identifier for multiple ebook formats? There is nothing innately hierarchical about the DOI, although as we saw with titles and chapters, it can represent hierarchies. Maybe the DOI could resolve to a page similar to the one Overdrive provides to library patrons, asking the reader which version they want to access. Currently actively working with scholarly ebook aggregators/hosts like JSTOR, Project MUSE, CUP and OUP. Have talked to others like ebrary, but haven’t made much headway there yet.
Question? Is there any overlap between the BISG Identifiers Committee and the BIG? Myself, Bill Kasdorf, APEX, Todd Carpenter, NISOTaylor & Francis, Springer, university presses and others are active.
CrossRef is an organization that relies on trust, collaboration, and networking effects. The more publishers that participate and follow the rules, the better the outcome for all participants.
