* ''Franchise/TheElderScrolls'':
** While not exactly a mundane item from the future, the title Elder Scrolls serve a similar function. They were written by a god and contain records of history: All that has happened, all that will happen (usually in the form of "If X happens, then Y and Z will happen, in that order"). They are extremely hard to read, causing blindness if read too often, but they are used by the emperor to secure the wellbeing of his empire, guiding his course of action.
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'' the player gets to read one themselves. If used near a temporal rift it lets them see an important piece of the past; used anywhere else it strikes them blind.
** What's more, they are absolutely and utterly immutable, such that they can change history, just by being read. In ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' the ultimate thieves guild quest involves stealing one in order to break a Daedric curse.

The scrolls have been used by the emperor various Imperial Dynasties throughout history to secure help guide the wellbeing of his empire, guiding his course of action.

*** The nigh-unstoppable warship belonging to the villain is also an example. In its own time period it is merely a mining vessel. Its ability to [[spoiler:blow up planets]] is due to something that they stole [[spoiler:from Spock]].

* "Mimsy Were the Borogoves" is a classic sci-fi short story by Lewis Padgett. A scientist doing an experiment in time travel realises he doesn't have anything to send back, so he grabs some of his children's educational toys and sends them back to 1943 (when the story was written) where they educate a brother and sister how to move into another dimension, which they do before their father's horrified eyes.

* The arm and CPU from the first Terminator in ''Film/TheTerminator'', left behind in the 1980's, brought about the rise of SKYNET. [[TimeyWimeyBall Well, sometimes.]] In any event, since the Terminator was sent back in time ''by'' SKYNET, this is also a StableTimeLoop...until it's broken by the destruction of the items in ''Film/Terminator2JudgmentDay'', which doesn't stop SKYNET from rising again in ''Film/Terminator3RiseOfTheMachines'' (where the novelization even implies that despite the destruction of the items, what had already been researched was aprehended by the military leading to SKYNET's creation). Yeah, TimeyWimeyBall.

* A non-time travel version occurs in the ''Series/StarTrekTheOriginalSeries'' episode "A Piece of the Action": A pre-Prime Directive starship 100 years prior had inadvertently left behind a book on Chicago gangs of the 1920s, which caused the civilization in question to develop into the original PlanetOfHats, with a culture based around 1920s gangsterism. After the crew has fixed the entire planet, [=McCoy=] leaves his communicator behind, alarming Kirk who worries that this trope will take effect.

* ''Series/StarTrekVoyager'':
** "Future's End" has a 29th Century timeship that was sent back to 1967. Interestingly, the 29th century technology helps create the "holo-emitter" the Doctor uses for the rest of the series, so the timeship was a TimelineAlteringMacGuffin to the 24th Century as well.
** The final episode leaves the possibility of this trope rather alarmingly dangling overhead. Future Janeway comes back over a decade to bring the crew home, decking out the ship in all kinds of future tech and eventually infecting the Borg Queen with a super nasty future virus. Now, given the Borg's ability to adapt, one can speculate that if they manage to overcome that virus, they would then have adapted to technology and programming the Federation hasn't yet invented. Not only that, but they had already assimilated her shuttle from the future by then, including the armor and the torpedoes. In the ExpandedUniverse novels, specifically ''Literature/StarTrekDestiny'', this comes back to bite them.

A tape of disco's greatest hits is accidentally left behind, where it's discovered by the past version of Roger the Alien, who becomes insanely rich and then goes broke riding the rise and fall of the disco trend.
