Acta are comprehensive and official notes recorded during a given meeting. If you don't remember who suggested weekly pizza parties at this week's Spanish club, you can check the acta.
The Latin word acta means "things that have been done," and it's used by academics and legal scholars for an official list of things that occur during a conference or meeting. The person who takes minutes or starts the video camera is responsible for the meeting's acta, which captures all the important information about the event. In ancient Rome, the Acta diurna, or "daily acts," was a publication that listed public events, lawsuits, official ceremonies, and more.
