Side Sewing
A "side sewn" book is one where the thread is passed through the thickness of the book on the edge nearest the spine side, or if you will, next to the left edge as one faces a closed book properly oriented for reading. The advantage of side sewing is the strength it offers. Many encyclopedias and text books as well as catalogs are side sewn. Midwest Editions can side sew and leave an exposed edge as in the example shown, or "case-in" the book with a hard cover, thus hiding the sewing. Side sewn books also offer economy. One down-side to a side sewn binding is opened books never lie totally flat.
