What is the order of the Ender's Games book?

There are three versions of the order of the series. The first one, by timeline:

Ender's Game

Ender's Shadow

A War of Gifts

Shadow of the Hegemon

Shadow Puppets

Shadow of the Giant

Ender in Exile

Speaker for the Dead

Xenocide

Children of the Mind

The second one, by release date (our library uses this one):

Ender's Game

Speaker for the Dead

Xenocide

Children of the Mind

Ender's Shadow

Shadow of the Hegemon

Shadow Puppets

Shadow of the Giant

A War of Gifts

Ender in Exile

The third one, as it appears on the list of "other books by Orson Scott Card" (I prefer to use this one):

Ender's Game

Ender's Shadow

Shadow of the Hegemon

Shadow Puppets

Shadow of the Giant

Speaker for the Dead

Xenocide

Children of the Mind

A War of Gifts

Ender in Exile

There are probably going to be more books, like the one being planned right now called Shadows in Flight, and there is also a book called The Authorized Ender Companion, but it is by a different author and is basically just side things, like an encyclopaedia of Ender subjects and movie news as of its publication date. Don't blame me if this answer goes out of date by the time you read it, because I'm not clairvoyant, I like to google things about Ender. You should try it some time.
