Work-search log: how detailed does it need to be? (Chicago)

I am keeping a spreadsheet of applications, but I worry it is not what the agency expects. I also did a résumé workshop at the library. What do you record?

I record the date, the company, the job title, how I applied and any contact name. It takes a minute each and it covered me when I was asked for proof.

Keep everything in writing and save the confirmation numbers. It saved me later.
