Ulrich's International Periodicals Directory is the most comprehensive resource to use when you need information about a specific journal, such as whether it's peer-reviewed, when it was published, or where it is indexed. 

Cabell's Directories of Publishing Opportunities provides contact information, acceptance rates, and impact metrics for journals, and allows for comparisons across journals.
