Abstract: An inexpensive automatic bookmark is provided, wherein the bookmark is made out of a unitary piece of material that is folded and coupled to itself to form the bookmark. The automatic bookmark has a body, a pair of attachment points for attaching to the covers of a book, and a placeholding arm that inserts and removes itself into the marked place in a book when the book is closed and opened, respectively. The bookmark is automatic in that once it is attached to the covers of a book, the bookmark functions to mark and unmark the location in the book by the mere closing and opening of the book.
