Q. 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.
