A Commonplace Book is a way to compile knowledge important to you. It can become a valued snapshot of you and your interests as you grow in your life and career. I was keeping a Commonplace Book for decades and didn’t realize I was doing it!
Commonplace Books might include quotations, connections to important literature or sources, meaningful articles, key data, journals (personal or professional), your curriculum vitae, and any other centralized information. They are often informal and may sit on your desktop, in the cloud, in your notes program, or maybe even in your In Box.
