Usage tips
Word structure and origin
The word 'Logbuch' (logbook) comes from seafaring. A 'Log' (a piece of wood) was thrown into the water to measure speed. So the 'Logbuch' (logbook) was the book in which these and other measurement data from the journey were recorded.
EXAMPLE
Der erste Offizier war für die Führung des Logbuchs verantwortlich.
The first officer was responsible for keeping the logbook.
Context clue
The original meaning refers to ships and aircraft. In a figurative sense, 'Logbuch' (logbook/log) is used very frequently today in IT for log files from servers or programs.
EXAMPLE
Der Pilot meldete den Vorfall im Logbuch des Flugzeugs.
The pilot reported the incident in the aircraft's logbook.
Typical verbs
Regardless of the meaning, the same verbs are often used for a Logbuch (logbook). You 'führt' a logbook (keep a logbook), 'macht einen Eintrag' hinein (make an entry in it), or 'überprüft' it (check it) to find information.
EXAMPLE
Bitte machen Sie nach jeder Änderung einen Eintrag ins Logbuch.
Please make an entry in the logbook after every change.

Logbuch vs Protokoll
protocol / minutes
'das Protokoll' and 'das Logbuch' are both written records of important information. 'Protokoll' is often used for meetings, negotiations, or experiments; it records the course and results. 'Logbuch' is more of an ongoing chronological record, classically on a ship or in an aircraft, but also in projects or IT. The words can be confused because both document things. Minutes often summarize a specific event, while a logbook collects entries over a longer period of time.
Logbuch
Der Kapitän trägt jeden Abend die Ereignisse des Tages ins Logbuch ein.
The captain enters the events of the day in the logbook every evening.
Protokoll
Im Protokoll der Besprechung stehen alle wichtigen Entscheidungen.
The minutes of the meeting contain all the important decisions.
