There are two stages to the process. Firstly, the nominations require a name, title, and a few sentences about the person you are nominating. The second stage occurs after the deadline (usually in the spring) when the Awards Committee will ask the nominator to submit more detailed supporting material about their candidate (nomination letter, CV, list of publications, and letters of support).
Nominations for awards in 2020 will open soon.
