We may indeed have it, and it's easy to check. Just go to the "Journals & Newspapers Listing" part of our web page, in the "Find Articles" section. Type in the name of the journal, newspaper, or magazine you are looking for, and see what you get. If we do have it, and it's online, you'll see the dates we have it for and a link to it. If we have it in print, there will be a link to the catalog record for it. If nothing comes up, we simply don't have it.
If you aren't sure what the results mean though, ask us, we're glad to help. And even if we don't have it, we can generally get things for you through interlibrary loan.
