Nice description of DOIs. But what’s CrossRef?

What members can
do...

• Refer to DOIs deposited with Crossref as
“CrossRef DOIs”
• Maybe--Prepend a descriptive “http” preﬁx to
every DOI displayed or printed.


Instead of THIS:
doi:10.1126/science.170.3965.1358-d

Maybe THIS:

http://doi.crossref.org/10.1126/science.170.3965.1358-d


Why?
• It says DOI

• It says CrossRef

• It’s a link

5.4 DOI Usability

• DOIs should be as concise as possible, in
consideration of human readability.


5.4 DOI Usability

• Often, hierarichal DOIs are more usable.
• The use of separators like “.” or “-” helps
• Strings longer than 6 of arbitrary-looking
numbers or letters interferes with usability,
even if the DOI is structured.

6.3 The Response or Landing Page

• A minimal response page must contain
• a full bibliographic citation
• some mechanism by which the user can
gain access to the full text


But where’s the
DOI?


7. Use and Display of DOIs

• a DOI should be displayed as (for example)
doi:10.1006/jmbi.1998.2354
• and the DOI identi er itself can be an active
link as in
http://dx.doi.org/10.1006/jmbi.1998.2354


7.1 Resolution Via the DOI Proxy

• The DOI Proxy server - http://dx.doi.org/ -
resolves DOIs. The DOI Proxy is the de nitive
resolution service for DOIs and should be
used for all DOI links.


7.3 Display of DOIs

• A DOI for a piece of content (article, book
chapter, conference proceeding) should also
be displayed in the header information for
the online AND print versions of the content


7.3.1 Displaying DOIs in print

• A DOI should be included in the header for
the print version of that article.
• Recommend listing the DOI -- for example --
as "doi:10.1006/jmbi.1998.2354". It is
possible to have the DOI followed by:
"available via http://dx.doi.org/".


?


7.3.2 DOIs in citations
• DOIs are a very useful addition to citations.
• The DOI should be the last element in the citation
irrespective of the format used.
• “doi:” should be lowercase with no space between
“doi:” and the start of the DOI.
• Publisher-speciﬁc URLs should not be used in
citations since they may break if the journal
changes ownership.
(CrossRef Reference Guidelines, http://www.crossref.org/08downloads/CrossRef_Ref_Guide_1_0.pdf )


7.3.3 DOIs in citation export
services
• Publishers should include DOIs in their
Download Citation/Export References” services.
• DOIs should be included as an identifier and as
the URL link using the “http://dx.doi.org”
resolver address.
• The DOI should also be included as a key
article identifier when such a field exists.
http://www.crossref.org/02publishers/guidelines.html


7.3.4 DOI as a reference link

• Use "CrossRef" as the display text for
reference links.


7.3.5 Instructions for Authors

• Publishers should include information about
using DOIs in their instructions for authors.

Take Aways

• CrossRef DOIs aren’t just for publishers and
geeks
• The more visible CrossRef DOIs are, the more
likely your investment will result in traﬃc
• We’re considering simplifying the display
guidelines--more later.
