Additional Commentary

ProQuest Dialog is a new subscription-based portal produced by Dialog that combines the Dialog and DataStar products, and Dialog representatives have stated publicly that Dialog hopes to eventually migrate all DataStar and Dialog product users over to ProQuest Dialog. No end date for this transition has been announced, but according to the May 2011 issue of Dialog Chronolog, the company representatives “have started to communicate with DataStar customers about the process for migrating to the new service.”[1]

Both subscription and transactional pricing options are available on ProQuest Dialog.[2]
