• 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.

• 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!

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

•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 is missing?
a. Funding informationb. CrossMark logoc. CrossRef DOId. CrossRef member logo

•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
