A logbook is a record of events on a voyage.[1] It is common practice for ships to maintain a log and fill it in daily.[2]
Overview
Logbooks typically contain detailed notes of events on a ship's voyage. They are updated daily and may include specific dates. Logbooks are maintained by various types of sailors, such as explorers and pirates.[1][2] The keeper of the log may be the captain of a ship or different individual designated to the task. A logbook may be preserved and passed down after the completion of the voyage, and as such act as an important historical record for future generations.[1][3][4]
Logbooks
Zeff's Logbook
Zeff kept a log detailing the brave exploits of the Cook Pirates one year voyage in the Grand Line, which was the pride of himself and his crew. The log survived the Cooking George being shipwreck, and afterwards resided at the Baratie with Zeff. Krieg aimed to steal it after Zeff denied his demand to hand it over to him. Krieg viewed having the log in his possession alongside with a pirate fleet as being able to obtain One Piece.[5]

- The final entry written on the day of Noland execution: "I saw the gold in the skull's right eye".[9]
Kouzuki Oden's Logbook

The samurai Kouzuki Oden initially began his journal in Wano Country based on tales he had heard of foreign sailors.[2] However, it later became a proper logbook after Oden managed to leave the country aboard the Moby Dick. It documents Oden's life and adventures with the Whitebeard Pirates and the Roger Pirates.[3] The logbook was salvaged from the burning Oden Castle in Kuri after Oden's execution 20 years ago and discovered in a river by Yamato. It subsequently remained in Yamato's possession for the next 20 years, before being passed down to Oden's son, Momonosuke.[4]
