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.
Thursday, November 12, 2009

Instead of THIS:
doi:10.1126/science.170.3965.1358-d
Maybe THIS:
http://doi.crossref.org/10.1126/science.170.3965.1358-d
Thursday, November 12, 2009

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.
Thursday, November 12, 2009

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.

• a full bibliographic citation
• some mechanism by which the user can
gain access to the full text

DOI?
Thursday, November 12, 2009

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.
Thursday, November 12, 2009

Thursday, November 12, 2009

Thursday, November 12, 2009

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
Thursday, November 12, 2009

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.

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.

• The more visible CrossRef DOIs are, the more
likely your investment will result in traffic
• We’re considering simplifying the display
