Find Articles page, and then the Journals & Newspapers Listing. Type in the title of the journal, magazine or newspaper (not the title of the article, the title of the journal it is in,) and then see what you get. It just depends, we may have it online, or in print etc., or we may not. We do have access to 30,000 plus titles, between what we have online and in the building, so your odds are good!
If your title shows in the list, and the date you're looking for seems to be there, that's great, just click on the link to the article database it's in and follow through from there. If it isn't, there may be a link to the catalog, and you can check that. If we just don't have what you need, we can generally get things from other libraries for you. Last but not least, if you aren't sure about all this, just ask us :-)
