You need to find out if Colby has access to the journal that the article appears in.
Search for the SOURCE TITLE (or the JOURNAL TITLE) in the CBB catalog.
Do a title search.
If Colby has the journal, the catalog will tell you what years we have,
If we have electronic access, or in paper, or microfilm, etc.
Then you can access it however it is available.
If we don't have the year you need, or we don't have the title, then you can request the title from another library through ILL (Interlibrary Loan). It usually only takes a few days, sometimes even less.
It will take you to a login page where you will need to register only once, then the system will remember your information and you can track all your requests.
