An endband is a part of a book, most often found with hardcover bindings, that consists of a small cord or strip of material affixed near the spine to provide structural reinforcement and sometimes decorative effect. An endband along the top edge of the book (as a book is standing upright) is called a headband, and one along the bottom edge is called a tailband.
As a physical object, a book is a stack of usually rectangular pages oriented with one edge tied, sewn, or otherwise fixed together and then bound to the flexible spine of a protective cover of heavier, relatively inflexible material. The technical term for this physical arrangement is codex. In the history of hand-held physical supports for extended written compositions or records, the codex replaces its immediate predecessor, the scroll. A single sheet in a codex is a leaf, and each side of a leaf is a page.
Bookbinding is the process of physically assembling a book of codex format from an ordered stack of paper sheets that are folded together into sections or sometimes left as a stack of individual sheets. The stack is then bound together along one edge by either sewing with thread through the folds or by a layer of flexible adhesive. Alternative methods of binding that are cheaper but less permanent include loose-leaf rings, individual screw posts or binding posts, twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack is either wrapped in a flexible cover or attached to stiff boards. Finally, an attractive cover is adhered to the boards, including identifying information and decoration. Book artists or specialists in book decoration can also greatly enhance a book's content by creating book-like objects with artistic merit of exceptional quality.
An endband, more so the headband, helps to resist the strain placed on the book when shelved upright with the spine facing outward, especially as it is common to pull a book out by hooking a finger over the top edge of the spine. Endbands were traditionally made from small pieces of vellum, catgut, or cord wrapped or braided with silk; though today they are separately manufactured ribbons. The endband is tightly sewn to the sections of the book where it can support the weight of the pages. When endbands are used for decorative purposes they may only be glued in place rather than sewn, though at a loss of reinforcing strength. [1]
A bookcase, or bookshelf, is a piece of furniture with horizontal shelves, often in a cabinet, used to store books or other printed materials. Bookcases are used in private homes, public and university libraries, offices and bookstores. Bookcases range from small, low models the height of a table to high models reaching up to ceiling height. Shelves may be fixed or adjustable to different positions in the case. In rooms entirely devoted to the storage of books, such as libraries, they may be permanently fixed to the walls and/or floor.
Vellum is prepared animal skin or "membrane" used as a material for writing on. The term is derived from the Latin word vitulinum meaning "made from calf", leading to Old French velin for "calfskin". Parchment is another term for this material category. If vellum is distinguished, it is by vellum being made from calf skin, as opposed to that from other animals, or otherwise being of higher quality. Vellum is prepared as a surface for writing to produce scrolls, single pages, codices or books.
Catgut is a type of cord that is prepared from the natural fibre found in the walls of animal intestines. Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle, hogs, horses, mules, or donkeys. Despite the name, catgut manufacturers do not use cat intestines.
