If you have found a citation to a newspaper article and want to see the entire article, you need to check if York University Libraries owns the newspaper. It could be in many formats - paper, electronic, or microtext.
The best place to start is OMNI. This will tell you what newspapers the Library owns in paper, microtext, and, in some cases, electronic format.
If you have problems finding a newspaper that you need, contact a reference librarian for further assistance.
