The magazines we subscribe to are kept for 1 year. However, EBSCO has many articles available.
Go to the Allen website then Library, select Database Access, then choose Academic Search Complete. You will need to log in with your student ID# and password (like myAllen).
On the search page, on the upper navigation bar, choose Publications, then search for Popular Science. You will see the years listed. You can choose the issue that you would like to search in by year, or you can search the whole publication.
