?
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?)
Participate in other collaborative services (CrossCheck, CrossMark)

DOI = Digital Object Identifier

Broken links are a problem

A DOI uniquely identifies a piece of electronic content

Why assign CrossRef DOIs to books Or, How does it help readers find my stuff?
Persistent linking -- books interlink with other journal articles and other scholarly content
Inbound links drive traffic; outbound links add value and utility
CrossRef Books DOIs can resolve to information on purchasing -- for both print and online books
Access/authentication remain under publisher control

It’s all about discoverability

Or, to put it another way
METADATA
is
MARKETING

Where do people discover CrossRef DOIs
Scholarly References
Abstracting & Indexing Services
Reference management tools
Search engines
Aggregated reference products
Online library catalogs (i.e. WorldCat)

112 publishers deposit book content at CrossRef
176,890 book titles
3,662,373 total book DOIs
Includes chapters and reference entries
The Numbers

Did you know…
50 million DOIs are resolved every month?

Books DOIs can resolve to…
Book Titles
Book Chapters
Reference Entries

…title level response pages for e-books

…title and book chapter response pages

…book chapters

…title level response page for print and e-books

…entries in reference works

4 million book DOIs out of 49 million CrossRef DOIs

Book DOI deposits have been growing rapidly

Best Practices Book DOIs
http://www.crossref.org/06members/best_practices_for_books.html

Best PracticesDepositing, 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.

Best PracticesAuthor guidelines
Instruct authors to cite specific chapters and entries using page numbers, chapter/entry titles and CrossRef DOIs.

Best PracticesEditorial Guidelines
Copyeditors add page numbers and chapter titles.
Use tools in production to correct references
Simple Text Query
eXtyles® Automated Reference Checking

Best PracticesUpdates and Versions
Major version – updates affect interpretation. Publisher will notify readers that content has changed. E.g.
errata
corrigenda
new editions
Minor version – unlikely to affect a interpretation. No publisher notification.

Signaling Versions of Record
Watch for CrossMark Version of Record Service later this year
http://www.crossref.org/crossmark/

Best PracticesUpdates and Versions
Do assign new CrossRefDOIs 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 CrossRefDOIs to minor new versions of books, chapters and entries.
Use CrossRef Multiple Resolution where appropriate to enable multiple URLs to be associated with one CrossRef DOI.

Best Practices: Citation MatchingBook Title Queries
Minimum query:
book title
book author
book year
And as many as possible of these:
editor (where appropriate)
book title
year
publisher

Best Practices: Citation MatchingChapter or Reference Entry Queries
Minimum query:
book title
book year
chapter author
first page
And as many as possible of these:
editor (where appropriate)
book title
year
publisher
chapter author (where appropriate)
chapter title
chapter first page

DOI syntax

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

Style Manuals
Provide the DOI, if one has been assigned to the content…. Use this format for the DOI in references:
doi:xxxxxx
Section 6.32
Providing Publication Data for Electronic Sources
Publication Manual of the APA, page 191.

Multiple resolution

There are DOIs that are not CrossRefDOIs
Other Registration Agencies have assigned DOIs to books for supply chain purposes.
More information is available here:

Multi-linking DOIs from Bowker

DepositingCrossRef Book DOIs
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

Steps to deposit
Determine the type of information you want to upload.
Create the XML file to upload using the CrossRef deposit schema.
Verify your XML:
http://www.crossref.org/02publishers/parser.html
Decide whether you want to upload the file synchronously (manually) or asynchronously (programmatically).
Pick the submission mechanism you want to use:
CrossRef web interface (synchronous)
Java or Perl scripts (asynchronous)
CrossRefVBClient
Web deposit form
Submit the file(s).

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

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

Chapter Level Metadata
Required data includes:
Chapter title
DOI and URL
Optional data:
Contributors
Pagination
Component number

Web Deposit Form
Manual DOI registration for books
System builds XML deposit file

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

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

CrossRef Search Plugin
