Frisk made a beeline for the library's history section as soon as they walked inside.
* The shelves are filled with books ranging from the history of different creatures to agriculture.
* This book is called 'The Hyrule Historia'
* Somehow a guide to a popular text adventure ended up in the history section...
Frisk had to focus to hear what the voice said afterwards.
* ...I didn't know It had a sequel, I wonder if Mom has a copy...
Papyrus found them and asked what they were looking for. Before Frisk answered they noticed the skeleton had already picked out a book.
* Papyrus found a guide for 'Mew Mew Love Life' a dating simulator. He doesn't realize it's fiction.
* The cover advertises exclusive concept art from the anime 'Mew Mew Cutie Mark Kiss'.
As Frisk told Papyrus of their plan to study the history of the seven sages, they wondered if the dating sim was any good. Papyrus replied that they should have followed him as he saw the book they were looking for.
* Someone put 'The Seven Sages: A Reference Guide' in the fiction section under 'S'.
Frisk grabbed the book, plopped down onto a cushion next to Papyrus and began to read.
