Bokomslag

Bokomslag is the outer cover of a book, typically consisting of a front cover, a back cover, and a spine; in hardcover editions it often refers to a detachable dust jacket that wraps around the case. The bokomslag serves several functions: protecting the binding, identifying the work, and attracting readers through art and typography.

The front cover usually displays the title, the author, and a principal image or design. The back cover often contains a blurb, an author bio, a publisher logo, an ISBN, and a barcode. The spine shows the title and author to help identify the book on shelves.

Design and production: Dust jackets are usually made of paper with printed images and may be glossy or matte; they can be laminated and sometimes include flaps that fold over the edges and contain additional information or a brief author note. In paperback editions the cover is printed directly on the card stock, while hardcover editions combine a case with a removable dust jacket.

History and impact: Dust jackets emerged in the late 19th or early 20th century as a way to protect cloth bindings and to provide a marketing surface. They became a standard feature for many genres and publishers, and are now an important part of a book's visual identity and branding.

Modern considerations: Some publishers choose to remove dust jackets for durability or cost, publishing with a printed cover directly on the boards; others use illustrated jackets as a deliberate design statement.
