Solution for the NEWEST tutorial world... (retested on 7/7/17)
This can be done in the tutorial, albeit with some reloading of the level.
Right when you load up the tutorial, skip it by pressing B when available. Take the first right after the stairs and look in the chest under the frames with the firework in them for 64 pages. Then, head back and to the left of the beacon. There are two frames with emeralds in them. Hit them to collect the emerald. (It may or may not count towards your total) Look into the chest and you'll find 30 more pages. Turn off autosave, then save the game. Then, trade the pages with the villager in the right pen for 3 emeralds.
Quit to the main menu, load up your save file, and you should spawn right in front of the villager with 94 pages. Turn off autosave again and repeat the process.
