In Poptropica's Time Tangled Island, Leonardo's notebook can be found in the Renaissance section. After you complete the tasks involving Leonardo da Vinci, head to his workshop, which is located in the area where you find him painting. The notebook is on the workbench in the workshop, and you can pick it up to complete the quest related to Leonardo.
In the Poptropica game "Time Tangled Island," the notebook can be found in the 1800s section of the island. Specifically, you'll need to enter the cabin of the inventor, where the notebook is located on a table. Collecting it is part of the quest to help fix the timeline. Make sure to interact with the items in the cabin to find it!
The notebook belongs to Leonardo Da Vinci, who is at 1516 AD (4 o'clock on the time device). In return for his notebook, he gives you the Glider Wings. (see related question)

When you give Lenord Da Vinci his notebook he will give you a glider.

If you "beat" the island, then the glider (a reward for returning the notebook) is already in your item bag.
