The Directory of Periodicals is a directory of publication information about the journals which are indexed in the Bibliography. The Directory has facts about subscription figure and information on a journal's peer review process. It is a good place to learn about possible journals to submit one's article or gather a list of journals relevant to one's scholarly interests (help guide)

Peer review is the process used by publishers and editors of academic / scholarly journals to ensure that the articles they publish meet the accepted standards of their discipline. Peer-reviewed and refereed are synonyms for the same process.
Not all journal articles are peer-reviewed because not all journals are peer-reviewed.
Articles in peer-reviewed journals are reviewed by a group of the writer's peers (other academics in their field) before the articles are published.
You can find out if a journal (and its articles) is peer-reviewed by searching for the journal title in Ulrich's.
The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar.
For example, a scholar with an h-index of 5 had published 5 papers, each of which has been cited by others at least 5 times.
