Zoom h4n Session Manager 2 (400kB zipped)
Contains both a printable PDF and the MS Word .docx files for managing sessions.
I personally use this template by keeping printed copies on hand with my Zoom at all times, and during field recording sessions I try to write down various notes about the take information for ingesting later.
Once at the computer I can save a digital copy of the session information with the word file and ditch the paper copy. Viola! no more paper to have to keep track of!
