Hogwarts Legacy Library Annex Field Guide Pages are collectibles that give you XP on pickup and are necessary to achieve 100% completion in Hogwarts Castle. There are 20 Field Guide Pages in the Library Annex, and to obtain all of them, you’ll have to run all over the area.
However, you need to have a keen eye for some of the collectibles, and even so, you’ll have a hard time finding them without knowing where to look.
Where To Find the Twenty Library Annex Field Pages in Hogwarts Legacy
The Library Annex area can be quickly accessed by opening your Hogwarts Castle map, selecting the bottom right flag, and fast-traveling to one of the five Floo Flames.
To move freely while looking for the collectibles, you should first unlock all the Floo Flames. Now, let’s go over each Library Annex Field Guide Page.
Field Guide Page #1 (Palmistry Model): In Front of a Palm Model
First, fast travel to the Divination Classroom Floo Flame, go up the spiral staircase east, head up the ladder, and go in front of the palm model on the table with the pile of cups. Cast Revelio to reveal the first Library Annex Field Page, named Palmistry Model.
Field Guide Page #2: Flying Above Some Wooden Beams
The second Hogwarts Legacy Field Guide Page is close to the Divination Classroom Floo Flame. Thus, head up the stairs northwest of the fast travel point and turn left to see the Guide Page fly above the wooden beams.
It may take a while for the collectible to appear in your sight, but hang in there; it will eventually come flying. When you finally spot the collectible, cast Accio to grab it.
Field Guide Page #3 (Arithmancy Classroom): Near Some Classroom Benches
Upon obtaining the previous Guide Page, head southwest on the wooden boards and go right as soon as you can to reach a door surrounded by animal symbols. For the third Library Annex Field Guide Page, you must solve an animal door puzzle.
First, start the puzzle by interacting with the door, which will then display two triangles. Focus on the top triangle, which has the number 9 in the middle and around it a question mark, the number 2, and a Hydra symbol.
To continue, you must know that each animal symbol has a number assigned to it. The Owl in the bottom left of the door is 0, the Unicorn above it 1, the Goat 2, and so on, going clockwise to reach the Kraken on the bottom right, which is 9. Therefore, the Hydra on the top triangle is 3. Now, the large number in the middle (9) is the sum of the smaller numbers and symbols around it.
This means the question mark can only be 4, represented by a Scruffy Owl symbol. Next, you have to interact with the triangle with the question mark left of the door to make it display the Scruffy Owl symbol. Then, follow the same logic for the bottom triangle on the door to determine that the two question marks stand for the number 3 (Hydra).
Interact with the triangle with the two question marks right of the door until it displays the Hydra symbol, and you’re done. You can now open the door and see one of the Library Annex Collection Chests. Head forward to reach another door you must go through, then cast Revelio near the classroom benches to make the next Hogwarts Legacy Library Annex Field Guide Page appear, named Arithmancy Classroom.
Field Guide Page #4 (Portrait Of Sir Cadogan): In Front of Three Paintings
The fourth Guide Page will take you to the Central Hall Floo Flame, from where you have to climb the stairs northwest, then turn around to climb two more sets of stairs. Now, head up the stairs southwest, turn around, and go in front of the three paintings on the left wall. Use the Revelio spell in front of the paintings to reveal the fourth Library Annex Field Guide Page, named Portrait Of Sir Cadogan.
Field Guide Pages #5, 6, & 7: Around the Central Hall Fountain
The next three Guide Pages are down the stairs northwest of the Central Hall Floo Flame. For one Page, you must cast Revelio next to the big fountain in the middle. As you can see, the collectible is named Central Hall Fountain. The other two Pages can be spotted flying above the stairs southwest of the fountain, and to grab them, you need to use the Accio spell.
Field Guide Page #8: Near Two Benches
After getting the previous three collectibles, head up the stairs north of the fountain to find an unlit brazier near two benches. Cast Confringo while aiming at the brazier to make another Library Annex Field Page appear.
Field Guide Page #9: In a Small Locked Room
The next Guide Page is down the stairs northeast of the Central Hall Fountain, then through the door southeast, for which you have to pick a level 1 lock using Alohomora. To reveal the ninth Library Annex Field Guide Page, cast Levioso while aiming at the statue in the small room you’ve just unlocked.
Field Guide Page #10: While Completing the Like a Moth to a Frame Side Quest
The tenth Guide Page can be obtained while completing the Like A Moth To A Frame side quest. You’ll find the collectible upon solving a moth mirror puzzle.
Field Guide Page #11 (Greenhouse Tree): Next to a Huge Tree
For the next Hogwarts Legacy Library Annex Field Guide Page, you must fast-travel to the Greenhouses Floo Flame. The collectible is on the other side of the huge tree next to the Floo Flame, and you must cast Revelio to see it. The Guide Page is named Greenhouse Tree.
Field Guide Page #12 (Dirigible Plums): In Front of a Tree
Upon getting Guide Page #11, head through the door northeast of the enormous tree and down the stairs. Use the Revelio spell in front of the tree next to the staircase to reveal another Library Annex Field Guide Page named Dirigible Plums.
Field Guide Page #13: Flying in the Library
Next, you should fast-travel to the Library Floo Flame and head up the spiral staircase to the southeast. Then, turn around to see the thirteenth Library Annex Field Guide Page flying around.
Field Guide Page #14: Above a Red Carpet
After obtaining the previous Guide Page, head southwest, and just before reaching the bookcase on the left side, go southeast. Don’t stop until you reach a ladder next to a bookcase, then turn right to see a black mirror above a red carpet.
Cast Lumos near the mirror to start a moth mirror puzzle, then return to the spiral staircase you used to get on this floor while looking for Page #13. Next to the staircase, without going down, you can see the moth needed for the puzzle on a book pedestal. Use Lumos again to make the moth follow you back to the mirror and reveal another Hogwarts Legacy Library Annex Field Guide Page.
Field Guide Page #15 (Enchanted Books): In Front of a Small Bookcase
For Guide Page #15, you must start from the Library Floo Flame and head northeast past the staircase to reach a gate. Go through the gate, then down the stairs, and make your way to the other side of the floor, where you should find more stairs. Head down these stairs as well to reach a display case on the left side with a small bookcase next to it.
Cast Revelio in front of the bookcase to reveal Library Annex Field Guide Page #15, which is named Enchanted Books.
Field Guide Page #16: Next To Some Book Piles
Make your way southeast from the previous collectible to reach the other side of the room, where you’ll find a door.
Go through the door, then down the stairs to get to a statue next to some book piles.
Use the Levioso spell while aiming at the statue to reveal the sixteenth Hogwarts Legacy Library Annex Field Guide Page.
Field Guide Page #17 (Statue Of Gregory The Smarmy): In Front of a Statue
The following Guide Page is fairly close to the Potions Classroom Floo Flame. Just head a couple of meters northwest of the Floo Flame and turn right to see a statue of a corpulent wizard. Go in front of the statue and use Revelio to see the next Library Annex Field Guide Page. The collectible is named the Statue Of Gregory The Smarmy.
Field Guide Page #18 (Professor Sharp’s Auror Badge): Next to a Lamp
For the eighteenth Guide Page, you must head through the door southeast of the Potions Classroom Floo Flame. Then, turn left to see a door on the right side leading to the Potions Classroom. Head to the table with the lamp at the back of the classroom and cast Revelio to reveal the eighteenth Hogwarts Legacy Library Annex Field Guide Page, named Professor Sharp’s Auror Badge.
Field Guide Page #19: Between Two Paintings
Upon collecting Guide Page #18, get out of the Potions Classroom and head down the stairs to the right to reach a door leading to a corridor. Head forward in the corridor and keep an eye on the right side to find another black mirror between two paintings on a tapestry. Use Lumos next to the mirror to start the puzzle and then proceed in the corridor to get to some stairs.
Climb the stairs, then go to the troll in the display case on the right side, where you’ll find the moth required for the puzzle. Cast Lumos near the moth, then guide it back to the mirror to reveal Library Annex Field Guide Page #19.
Field Guide Page #20 (Gorgon Portrait): In the Middle of Some Statues
The last Guide Page will require you to solve another animal door puzzle which you can find in the room with the troll in the display case from where you got the moth for collectible #19. The door with animal symbols is southwest of the display case, and you have to interact with it to start the puzzle.
To solve the puzzle, follow the same logic you used for Guide Page #3. As such, after some quick math, you’ll learn that the question mark on the top triangle is a 2 (Goat). Go to the triangle with the question mark left of the door and interact with it to roll the Goat symbol.
Then, get back to the door to figure out that the two question marks on the bottom triangle stand for the number 1 (Unicorn). Interact with the triangle with the two question marks on the wall to the right of the door to make it display the Unicorn symbol. Now open the door and cast Revelio near the painting in the middle of the statues to reveal the last Guide Page, named Gorgon Portrait.
