Every new student is given a free copy of the "C# Yellow Book" when they arrive in Hull. The book is also available as a free download and you can get a copy via Amazon for your Kindle.
Each year the cover has something yellow on it. This is the "custard" edition (sometimes referred to as the "Pyrex" version.
There are a number of translations available, and this will soon include the Korean language.
Rob Miles of the department has just signed a contract for the production of a Korean version. You can pick up your digital copy, along with the entire First Year C# course that we teach, at www.csharpcourse.com
