Wikisimpsons - The Simpsons Wiki
The Simpsons Library of Wisdom is a series of books, each related to a specific character of the popular cartoon show The Simpsons. Thus far, 10 books in the series have been released. The books feature details on characters and locations in Springfield, and character-specific features. Each book has the respective character's top 40 and bottom 40, and a day in the life of that character.
 Series 1 - 2004
The Bart Book was released in the first series of the Library of Wisdom. The book was similar to the book Bart Simpson's Guide to Life, and the character biographies were also similar to the ones in the Complete Guide series.
The Homer Book was released in the first series of the Library of Wisdom. The book received better reviews than The Bart Book, due to the fact there has not formally been a Homer-devoted book.
 Series 2 - 2005
From the second series, the books changed slightly. The books no longer contained character biographies, and instead contained more locations pages. The covers from each region had a lot of differences.
The Ralph Wiggum Book was released in the second series of the Library of Wisdom. This book features the "wisdom" of Ralph - namely poems from him (including "The Other Little Ringworm"), a story of "Wigglepuppy", his imaginary canine friend and various quotes from him including: "I eat corn!" and "Satan told me to tell you "Hi"".
Comic Book Guy's Book of Pop Culture was released in the second series of the Library of Wisdom. The book breaks a pattern in the title by not being called "The Comic Book Guy Book". This book is mostly about Comic Book Guy's take on Popular culture, and little about the actual character himself.
 Series 3 - 2006
These books were released on September 18, 2006. It was the third series and again, included two books. Fans were happier with these new books, as they focus on main characters, rather than secondary ones such as The Ralph Wiggum Book. These books got the character profiles back.
The Lisa Book was released in the third series of the Library of Wisdom.
The Krusty Book was released in the third series of the Library of Wisdom.
 Series 4 - 2008
The two books for series 4 are similar to the series 3 books as they focus on main characters as well.
The book about Ned Flanders was released in the fourth series of the Library of Wisdom and contains a comic book of virtues, character profiles (God, Maude, Rod and Todd), Ask-Aroonie the Nedster! Ned Answers Kids' Questions About Religion and A Ned Flanders Cookbook.
The Book of Moe was released in the fourth series of the Library of Wisdom. It includes a lot of information about Moe's love life: (Perfect Dates, Perfect Moe-Ments), (20 Types of Dates) and (Moe's tried and almost successful pickup lines). It also doesn't contain any character profiles.
 Series 5 - 2009/2010
The Chief Wiggum Book of Crime and Punishment is a book detailing Clancy Wiggum's career as a police officer in Springfield. It contains humorous anecdotes of fighting crime in Springfield, as well as insight into the police force's general laziness. There are also amusing laws from the United States and from around the world added to pages throughout the book.
