Book collecting is the collecting of books, including seeking, locating, acquiring, organizing, cataloging, displaying, storing, and maintaining whatever books are of interest to a given collector. The love of books is bibliophilia, and someone who loves to read, admire, and a person who collects books is often called a bibliophile.
Book prices generally depend on the demand for a given edition which is based on factors such as the number of copies available, the book's condition, and if they were signed by the author (and/or editor or illustrator, if applicable) or by a famous previous owner.[1] For example, a first edition “And To Think That I Saw It On Mulberry Street” can reach the price of $12,000 in the best condition.
