Maintaining Journal Titles
Title and ISSN combinations are determined by the publisher.
A valid ISSN is required for all journal titles
The title / ISSN combination in your deposit must match the title / ISSN
combination in our system.
If a title changes, a new ISSN is required
Journals should be deposited under the original title
Title list: http://www.crossref.org/titleList/
Do not create new DOIs if DOIs already exist!
A DOI prefix indicates who created the DOI, not who owns the DOI
It’s just a way to make sure DOIs are unique across registrants
When you acquire a title, you’ll probably acquire existing DOIs.
Acquired DOIs should be redirected to your content
Title transfer policies: http://help.crossref.org/#ID5855

Reports!
The overall resolution failure rate for all publishers is 4.1896%
and your failure rate is 6.0445%.
‘Bad’ DOIs
compiled from reports submitted by end users
emailed nightly to technical contact
DOI Error report (emailed nightly as needed)
Reasons for DOI Error:
a DOI has been published but not deposited
the published DOI does not match the deposited DOI
the end user misinterpreted or mistyped a DOI (i.e.
confusing 1 for l or 0 for O)
Conflict report
Why are conflicts bad?
Only one DOI should be assigned per item
Queries will return multiple DOIs, causing confusion
Some queries (OpenURL) may not return a DOI if multiple results
are present
Conflicts between two DOIs often result in one of the DOIs being
neglected
