A common separation by content are fiction and non-fiction books. This simple separation can be found in most collections, libraries, and bookstores.
Fiction
Many of the books published today are fiction, meaning that they are in-part or completely untrue. Historically, paper production was considered too expensive to be used for entertainment. An increase in global literacy and print technology led to the increased publication of books for the purpose of entertainment, and allegorical social commentary. Most fiction is additionally categorized by genre.
The novel is the most common form of fiction book. Novels are stories that typically feature a plot, setting, themes and characters. Stories and narrative are not restricted to any topic; a novel can be whimsical, serious or controversial. The novel has had a tremendous impact on entertainment and publishing markets.[22] A novella is a term sometimes used for fiction prose typically between 17,500 and 40,000 words, and a novelette between 7,500 and 17,500. A Short story may be any length up to 10,000 words, but these word lengths vary.
Comic books or graphic novels are books in which the story is illustrated. The characters and narrators use speech or thought bubbles to express verbal language.
Non-fiction


A page from a dictionary
In a library, a reference book is 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. An almanac is a very general reference book, usually one-volume, with lists of data and information on many topics. 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, and other information 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 and biological abstracts.


An atlas
Books with technical information on how to do something or how to use some equipment are called instruction manuals. Other popular how-to books include cookbooks and home improvement books.
Students typically store and carry textbooks and schoolbooks for study purposes. Elementary school pupils often use workbooks, which are published with spaces or blanks to be filled by them for study or homework. In US higher education, it is common for a student to take an exam using a blue book.


A page from a notebook used as hand written diary
There is a large set of books that are made only to write private ideas, notes, and accounts. These books are rarely published and are typically destroyed or remain private. Notebooks are blank papers to be written in by the user. Students and writers commonly use them for taking notes. Scientists and other researchers use lab notebooks to record their notes. They often feature spiral coil bindings at the edge so that pages may easily be torn out.
