To find articles on your topic, you may want to consider using Articles+. You search in it similarly to how you search in the catalog; however, you may feel overwhelmed by the number of results you find. If you need to find fewer, more specific results
If you don't want to mess with your search terms but do want to try an narrow things down, try using filters.
Filters can be seen on the left-side of the screen once you have started your search in Articles+. They include: "Content Type", "Discipline", Publication Date", "Subject Terms" and "Language".
Once you do this, a box will open on your screen (typically on the right) and it will show you different subjects that have been associated with your article:
Find one or two that best fit with your topic and change your search by selecting the "options" button
This will take you to the advanced search feature. From there change the "All Fields" button to say "Subject Terms" and search. This will significantly narrow down your results.
