Search the indicated locations to find all ten Black Cat journal audio logs. Five of Black Cat's journals can be found during Story missions. The other five are hidden in the open world. If you fully upgrade your Spider-Sense, they will be highlighted on the mini-map when you get close to them. Pause the game, and select the "Messages" tab to see exactly which logs have been found. Each journal has its own number, allowing you to keep track of which ones are missing.
