To make a lectern in Minecraft, you need the following materials:

• Four wooden slabs (any type of wood slabs will work, and you can mix different types)
• One bookshelf

Steps to craft a lectern:

1. Make a Bookshelf:
   • You need 3 books and 6 wooden planks.
   • Arrange the 3 books in the middle row of the 3x3 crafting grid.
   • Place 3 wooden planks in the top row and 3 wooden planks in the bottom row.
   • This will craft a bookshelf.
2. Make Wooden Slabs:
   • Place 3 wooden planks in a horizontal row in the crafting grid to make 6 wooden slabs.
3. Craft the Lectern:
   • Open the 3x3 crafting grid.
   • Place 3 wooden slabs across the top row.
   • Place 1 bookshelf in the center slot (middle row, middle column).
   • Place 1 wooden slab in the bottom middle slot.
   • This arrangement will craft a lectern.
4. Move the lectern to your inventory.

The lectern can be used as a job site block for librarian villagers or to hold books for reading
