I need the description of an undergraduate class I took.
BYU Undergraduate Course Catalogs are available online through archive.org. Below is an easy access path:
http://lib.byu.edu/collections/byu-history/ > select "University Publications" > scroll down to "Course Catalogs 1901-2015" > now select the year from the drop down arrow.
You will be connected to the Internet Archive scanned version of the yearly course catalogs from 1901 > You can scroll page by page through the scanned version of the catalog for the year you chose.
