Narrative:

Came back from first break and replaced first officer; went to look something up in the operations manual; and realized that I had the wrong charts in the flight bag for the first officer position. I told the captain who said that they had already discovered this; while I was on break. We checked that we had all necessary charts and manuals. We then sent a message to the company and continued uneventfully.
