How can researchers and librarians find out about updates, corrections and retractions once a scholarly research paper is published? CrossMark is the tool that enables publishers to communicate these changes. Watch for this logo on a publication to check the status:
CrossMark is a service of CrossRef, the same folks who bring you the DOI (Digital Object Identifier) that is on many articles today.
