Document classes for book in LaTeX

Here are some of the document classes that can be used to create a book using LaTeX:

Book

The default class. Looks dated and ugly.

documentclass{book}

Memoir

Looks modern. Better than the default book.

documentclass{memoir}

AMSBook

Looks good, but can only be used for math books. This is because all headings are centered (not left-aligned) and all text is center-justified too.

documentclass{amsbook}

ScrBook

This is from the European designed KOMA package which looks modern and the fonts are nice. While their article class is nice, I did not like the book class that much.

documentclass{scrbook}

Tufte-LaTeX

Using this gave me compilation errors which I could not resolve. Thats a pity because this style looks almost like the books from Tufte.

Bookest

Beautiful book class and my favorite.

documentclass{bookest}

Octavo

Produces beautiful pocket books.

documentclass{octavo}

Caesar

Another nice looking book class.

documentclass{caesar_book}
