What type of notebook can be used for field notes?

The use of any kind of notebook for field notes is valid because field notes serve a practical purpose in documenting observations, evidence, and thoughts while in the field. The key aspect of field notes is their functionality rather than the specific type or brand of notebook used. Field notes can be written in various forms, such as bound notebooks, loose-leaf paper, or even digital formats, depending on the needs of the individual taking the notes. Using any kind of notebook allows for flexibility in situations where specific branded or government-issued notebooks might not be readily available or necessary. The primary objective is to capture information accurately and efficiently, regardless of the medium used.
