Bookcrafts Glossary

Binding Edge:This is the edge that is bound to form the spine.
Book Block:A collection of pages glued together without a cover.
Cameo Window:Is fully cut-out and the print is mounted beneath the cover.
Endpapers:The pages at the front and back of the book, glued to the cover, sometime known as the flyleaf.
Folio:This is when your book is open and you see 2 sides, including the left and right.
Fore Edge:The edge of the book that opens, parallel to the spine.
Landscape:A horizontal book – spine on the short edge. Eg. 11x14 means it will be 11” high and 14” wide.
Leaf:A single sheet of paper in a book (two sides). When a folio is folded in half it forms 2 leaves which gives you 4 sides.
Page:One side of a leaf. We just call it a side.
Perfect Binding:This is where we glue single pages together.
Photo Inlay:A photo is mounted to an inlay in the cover.
Portrait:A vertical book – spine on the long edge. Eg. 14x11 means it will be 14” high and 11” wide.
Quarter Binding:This is where the spine of the book is covered in a different material, or colour, than the rest of the book.
Sections:A group of folios prepared for sewing.
Spine:The side of the book where the pages have been glued together.
Stab-Sewn:This is where the stitching of the spine is done vertically through the pages.
Typesetting:Individual letters set in Ludlow metal to create a word for embossing.

To sum up the pages problem:

1 page = 1 side 1 folio = 2 sides 1 leaf = front and back side

To remember this easily – when you open a book flat you see a folio. You read a side and you turn a leaf.
