An author is the creator or originator of any written work such as a book or play, and is thus also a writer. More broadly defined, an author is "the person who originated or gave existence to anything" and whose authorship determines responsibility for what was created.[from wikipedia]

The title of a book, or any other published text or work of art, is a name for the work which is usually chosen by the author. A title can be used to identify the work, to place it in context, to convey a minimal summary of its contents, and to pique the reader's curiosity. Some works supplement the title with a subtitle. Texts without separate titles may be referred to by their incipit, especially those produced before the practice of titling became popular. During development, a work may be referred to by a temporary working title. A piece of legislation may have both a short title and a long title. In library cataloging, a uniform title is assigned to a work whose title is ambiguous.[from wikipedia]

In library science and architecture, a stack or bookstack (often referred to as a library building's stacks) is a book storage area, as opposed to a reading area. More specifically, this term refers to a narrow-aisled, multilevel system of iron or steel shelving that evolved in the nineteenth century to meet increasing demands for storage space. An "open-stack" library allows its patrons to enter the stacks to browse for themselves; "closed stacks" means library staff retrieve books for patrons on request.[from wikipedia]
