What are manually recorded items of information kept at designated locations on a position of operation called?

The term used to describe manually recorded items of information kept at designated locations on a position of operation is typically associated with "written notes." This term encapsulates a broad range of information that controllers might jot down during operations, including important instructions, changes in flight status, or other relevant data that needs to be referenced quickly.

Logs generally refer to systematic records, often associated with specific data over a period, while reports imply a structured compilation of information that may need to be submitted or presented rather than casually recorded. Diary entries, on the other hand, suggest a more personal or chronological account of events rather than a functional record directly relevant to operational duties. Therefore, "written notes" is the term that incorporates the essence of informal, yet critical, ad-hoc documentation necessary for efficient and accurate control in the en-route environment.
