Journals are a particular kind of periodical that are cited differently than popular magazines. In addition, there are two ways to cite journals depending on if they are continuously paginated or not. Continuously paginated journals begin the first issue of a volume on page number one and, with each successive issue, continue on until the last page of the last issue in the volume is reached. You need to include the volume number but not the issue number in a citation for a continuously paginated journal. Non-continuously paginated journals begin each issue of a volume on page one and run through the last page of the issue.
Subsequent issues begin again at page one.
Non-continuously paginated journals must include both the volume and issue numbers in the citation. You can't neccssarily tell how a journal paginates its issues if you've retrieved a full text article from an electronic database. In that case, cite the article as if it is a non-continuously paginated journal, including both the volume and issue numbers. If the first article starts with a very low page number, that doesn't necessarily mean the journal doesn't use continuous pagination. Take a look at two consecutive issues of the journal.
