Sazed’s Copperminds, Mistborn by Brandon Sanderson:

• Copper bracers called copperminds that contain many, many forbidden books. They are accessible only to Sazed, a scholar specialising in religion and also a member of the Skaa rebellion.

‼️MAJOR SPOILERS‼️

At the end of the trilogy, the world is literally about the end, and Sazed becomes a god and uses the knowledge in his copperminds to fix/remake the world.

ART’s archives, The Murderbot Diaries by Martha Wells:

• “My onboard archives are extensive. Why haven’t you sought access to them?” Of course a research vessel would brag about its research library. Why wouldn’t it?

Sunai, The Archive Undying by Emma Mieko Cando:

• He contains a living AI god referred to as an Archive. He is a relic who can interface with other archives and falls in love with a cute boy when he normally runs away from all attempts at intimacy and keeps being like oh? I…like him?

Merlin’s Library, The Magic Tree House series by Mary Pope Osborne:

None

The Scholomance Library, A Deadly Education by Naomi Novik:

• The library inside the Scholomance is so cool. It’s open to a void above, and is the safest place inside the entire school. The sections are mostly in the same place every time. But the shelves can stretch out and fill up with more books

The Thunderhead, Arc of a Scythe by Neal Shusterman:

• It contains the collective knowledge of humanity and is a perfect, almost-sapient AI that doesn’t follow the “utopia is actually dystopia” trope

• Sentient building! Is literally a place of learning, both through read knowledge and real life experiences; has various doors to different locations and worlds, as well as specific areas inside the library for physical learning. The Library can manipulate space-time within itself, and paintings can easily become doorways to pocket dimensions.

The Stormlight Archive, The Stormlight Archives by Brandon Sanderson:

It was meant to preserve information stored for thousands of years after books in the main archive has turned to dust.
