First, ask the professors in your department about which publications are important to your discipline. They are the ones who know!
Next, look to see if the library can give you access to the publication.
Go to the Library website and select "Journals by Title" from the "Research Help" drop-down menu. This feature allows you to search by the name of individual publications.
Search by the name of your publication. Be careful - there are often many publications with similar names! Look to see where a publication originates if you have multiple results. Select "Online Access" to go to the entry for your publication. You can browse issues or search within the publication.
