So you're a Fish out of Temporal Water who's just come back to the world either through Time Travel, cryosleep, coming Back from the Dead, or maybe you've just been away for a while. You've surely missed out on a lot, so you better study up! Whether through intense reading, television, the internet, or other means, this trope is when a character catches up on history through some sort of means.
- Ushio and Tora: The demonic Tora likes sitting in on Ushio's school classes because it lets him find out about things that had happened and been discovered after he was sealed.

- Zombie Land Saga: Most of Franchouchou has been dead for over a decade and are all varying degrees of Fish out of Temporal Water. Ai takes advantage of their producer's computer to catch up on phenomena from the years she's been away, specifically on the idol trends that have come and gone, to gain a better advantage for the group to progress in popularity.
- The chapter "Departure" from the Avantasia Protag AU series deals with when Aaron (from the Victorian era) first found himself mysteriously transported to the modern day. After figuring out his situation and securing shelter, he finds the local library and spends all his free time for weeks or even months there reading everything to catch up. Not just history, but modern mechanics and science too.
- Lampshaded when the library employees gossip about his strange habits and choice of books, including instruction manuals, and jokingly suggest he's a time traveler. Little do they know it's true.
- In the My Little Pony: Friendship Is Magic fanfic Progress, Princess Luna has to catch up with all the inventions and developments that happened during her thousand-year exile to the moon.

- In Captain America: The Winter Soldier, Steve Rogers is still adjusting to the modern era (though pleased with a lot of the advancements, especially The Internet which is useful for this trope) and has been making a list of all the things that he needs to catch up on. The exact items on the list varied depending on the international market in which the movie was playing, as this article illustrates. It also notes that Star Wars, Star Trek, Rocky, Nirvana, Marvin Gaye's Trouble Man soundtrack and Thai food are on every iteration of the list. Later in the movie, Natasha makes a WarGames reference, but when she starts explaining it to Steve he says he's already seen it.
- The Fifth Element: When the Supreme Being Leeloo is regenerated From a Single Cell, she catches up on the last 5000 years of human history by speed-reading the encyclopedia. This causes some difficulty when she gets to the entry on War.

- Star Trek IV: The Voyage Home: Dr. Gillian Taylor makes the trip to the 23rd century along with Admiral Kirk and the crew of the late USS Enterprise along with the humpback whales they came back to retrieve to respond to a probe looking for such whales. After the crisis is concluded and Kirk is busted down to Captain for his actions in The Search For Spock, Taylor tells Kirk that she accepted a position on a science vessel in order to do "300 years of catch-up learning."
- In The Matrix, a variation occurs where Neo (and, presumably, every other human rescued from the Matrix) learns that history as he knows it was just a deeply immersive virtual reality simulation (albeit one based on real history) and learns via another such simulation that the actual present world is a bombed-out radioactive wasteland ruled by The Machines with the vast majority of humanity now grown in pods and plugged into an artificial dream world.
- In Superman: The Movie, Jor-El leaves his son Kal-El a hologram to be watched when he turns eighteen years old that explains his Kryptonian origins. The hologram is also full of information about Earth's history to better explain why Jor-El sent the child there: he wants Kal to serve as a Hope Bringer to humanity. Unfortunately, this opens up a Plot Hole, as it's never explained exactly how Jor-El knew so much about Earth's history when Krypton was billions of miles away in the first place; Jor-El also specifically says that time flows differently on the two planets, as "many thousands of your years" will have passed when Clark/Kal turns eighteen, meaning that Krypton was millennia ahead of Earth in terms of development.
- Animorphs: In Megamorphs 3: Elfangor's Secret, when the Animorphs travel through time to Set Right What Once Went Wrong, Tobias reads a history textbook to find out what changed in that timeline (the most major changes being the failure of the American Revolution and Nelson losing the Battle of Trafalgar).

- Oona Out of Order: For Oona's first leap (from 1982 to 2015), Kenzie helps her to catch up. To avoid overwhelming her, he suggests she start with iTunes and Wikipedia. He lets her pick his brain about events like 9/11. She is surprised that a Black man has become president and that gay marriage is legal.
- Extraordinary*: In the Distant Finale, Mutual is mentioned to have spent a lot of time catching up on what he missed, since he spent seven years on his parents' farm in Alaska with no contact with the outside world. At one point he managed to get his hands on a couple music and celebrity gossip magazines, which helped a little, but after he escapes he has to spend a lot of time using the internet and TV to catch up on the pop culture and history he missed. As his girlfriend Jen puts it, "The week he discovered Maxim magazine was not my favorite week."
- In Tales of the Magic Land, evil sorceress Arachna wakes up after a five thousand-year-long enchanted sleep and spends many days afterwards reading the chronicle of the Magic Land to find out what the country is like at present and especially if there are any strong witches and wizards she should be wary of.
