Q. How do I find out if the library has a specific journal or magazine?

If you are looking for a specific periodical title, the best way to search is using the Periodical Portal.  From the library home page,   on the Blue Bar, click Search.  Then click on Library Collections.  In the blue box, click on the last item, Periodical Portal.

Then type in the title or part of the title. In the results list, you will find a list of matching titles along with which database has copies of the periodical.
