This guide is intended to complement the What Was I Thinking? book display in Parks Library. The purpose of both the guide and the display is to show how the concept of memory is approached and examined in a variety of fields -- from literature and the arts to science and technology, from cultural history to psychology. The flipside of memory -- forgetting -- is also included here. Please enjoy this guide, and hopefully the physical display as well, and let us know if you have any comments or questions!
