Hi Shannon,
Perhaps some issues of College Bazaar are buried amongst digitized issues of Harper's Bazaar. Over the years I've come across some hidden gems of digitized periodicals on various platforms that were related to the indexed title. Usually the vendor or publisher is unaware these issues from a different periodical are even available on the current iteration's main page. What years are you looking for?
Do you have access from 1867 to current through ProQuest?
