Biblio's Journal Article publication type contains fields suited to this type of publication.

To begin, go to Admin menu > Content > Add Content > Biblio.

Once the page loads, from the Publication Type drop-down, select Journal Article. Notice that there is also a Journal type - try not to get these mixed up. If it does not automatically redirect you, click Next.

On this next page, enter the Title of the journal article, and a bit lower, enter the Author(s). Many authoring options are available, including editors and corporate authors. If you would like to provide a cover image, click Choose File, select a file from your computer, and click Upload. A preview should appear in the form. 

Click the Publication tab to the left, and fill out as much information as you have/can. 

Keywords are another field we really like to have, because they help categorize and filter articles by subject and type.

You can choose to fill out other fields in other tabs, if you wish.

When you're done scroll to the bottom of the page and click Save

When you've saved, you will be presented with a nicely formatted table of information about this particular article. Clicking on the Author link will list all publications by that author, and clicking on Keyword links will list all publications on the site that contain that keyword. There are also links below the table to search Google Scholar for the article and to view the information in a variety of popular formats.
