Abstracting and Indexing publishers, though, not eligible for membership, quickly became able to participate as Affiliates.

– Can query the system for DOIs and metadata– Can get bulk updates of metadata– Can act on behalf of members

83 Non-Publisher Affiliates

What do academic & research libraries have to do with CrossRef?

a. They send metadata queries to discover DOIsb. They use CrossRef metadata to direct their users to the

licensed copy of an articlec. They assign DOIs to scholarly documents hosted in

institutional repositoriesd. They educate students on reference skills including using

DOIs in academic paperse. All of the abovef. None of the above

e.

CrossRef has 2000 Library Affiliates

• Library Affiliates do substantial volume of querying at CrossRef

• Link Resolvers supplement library user metadata with CrossRef metadata and/or DOIs. The link resolver looks up institution’s holdings to direct users to a licensed copy.

• Libraries join CrossRef as Publisher Members to assign DOIs to content.

Works with Publishers, Libraries, and others

What is Forward Linking?a. A way to tell which of your article references

will have content to link to in the future

c. Another name for CrossRef Cited-By Linking

d. All of the above

e. None of the Above

C.

Cited-by Linking• Forward Linking was the original name for

Cited-By Linking, because links would be created to the article (not from the article) after subsequent articles cited it.

• Forward Linking should not be confused with Stored Queries, which save unmatched queries at the time of production and alert the publisher when DOIs are assigned to the non-matched references.

b.

343 million Cited-By links

25 million CrossRef DOIs with Cited-By links

19 million documents with references

CrossRef Services for Publishers

• DOI Reference Linking

• Cited-By Linking• CrossCheck

• CrossMark• FundRef

What is the recommended format for displaying CrossRef DOIs?

a. 10.5703/1288284314959

b. DOI: 10.5703/1288284314959

c. doi: 10.5703/1288284314959

d. Doi: 10.5703/1288284314959

f. http://dx.doi.org/10.5703/12882843l4959

g. All of the above

h. None of the above

• DOIs should be displayed as URIs (aka URLs) so they are not only unique, but also actionable.

• Displaying DOIs as URLs allows machines to follow DOIs, allows humans to use browser tools such as open in a new window, copy, etc.

• And, it makes it clear to readers what they should do with them—Click!

Which of the following is an acceptable format for displaying

CrossRef DOIs?a. http://dx.doi.org/10.5703/1288284314959

b. http://dx.doi.org/10.12932/AP0268.31.2.2013

c. http://doi.org/jhc

d. All of the abovee. None of the above

d.

• DOIs should be displayed as URIs (aka URLs) so they are not only unique but they resolve.

• Unwieldy DOIs can be shortened at shortdoi.org. Or better yet, choose a short naming scheme.

• CrossRef has exhausted all the “10.” prefixes with 6 digits and earlier this year began assigning 7 digit prefixes.

Take a look at the following page

What’s missing that causes it to be out of compliance with

CrossRef’s rules?a.Funding information

b.CrossMark logo

c.DOI

d.CrossRef member logo

c.

• Publisher response pages must include the DOI, ideally in URL format, even though the link resolves to the same page.

• Displaying the CrossRef Member logo is a best practice, but not required.

• CrossMark is an optional service of CrossRef, so the logo is not required for non-participating publishers

• Funding disclosures are good practice, but not required by CrossRef
