You can refine your journal article search in a number of ways to narrow your results (using the left-hand pane of the search screen).
Find journal articles in Discover
Select Journal articles from the drop down menu and search for your keywords.
Use the left side menu to refine your search (Peer Reviewed Journals, Articles, Date range).
You can remove these refinements under your Active filters.
Lock active filters if you want to change your search but keep the active filters. Either select Remember all filters (to keep all) or hover over one filter and select the padlock (to keep that filter). Any filter that has been locked will remain each time you search. You can remove one filter using the X or remove all with Reset filters.
