In a library, a general type of non-fiction book which provides information as opposed to telling a story, essay, commentary, or otherwise supporting a point of view, is often referred to as a reference book. A very general reference book, usually one-volume, with lists of data and information on many topics is called an almanac. An encyclopedia is a book or set of books designed to have more in-depth articles on many topics. A book listing words, their etymology, meanings, etc. is called a dictionary. A book which is a collection of maps is an atlas. A more specific reference book with tables or lists of data and information about a certain topic, often intended for professional use, is often called a handbook. Books which try to list references and abstracts in a certain broad area may be called an index, such as Engineering Index, or abstracts such as Chemical Abstracts, Biological Abstracts, etc.
Papyrus, a thick paper-like material made by weaving the stems of the papyrus plant, then pounding the woven sheet with a hammer-like tool, was used for writing in Ancient Egypt, perhaps as early as the First Dynasty, although the first evidence is from the account books of King Neferirkare Kakai of the Fifth Dynasty (about 2400 BC). Papyrus sheets were glued together to form a scroll. Tree bark such as lime (Latin liber, from there also library) and other materials were also used.
