Ulrich's Web which can be found in our list of library databases can tell you if a journal is peer reviewed as well as where it is indexed online.
You can search by a specific journal title or by keyword under the advanced search option. Be sure to select "keyword" from the drop down menu if you would like to search that way. In this example I've narrowed my search to active, academic journals, published in English.

Once you pull back results you can continue to narrow your search. Ulrichs contains icons to quickly show you if a journal is electronic web based only, refereed, or on open access publication.

Once you click on a specific journal title you can find out how often they publish, where you can find that journal full text in an electronic database, and where you can find the citations indexed in electronic databases.
