This is the book with the most pages on Delphi that I've ever seen (almost 1500).
No wonder, since virtually every topic is treated in this book.
Marco loves completeness, both in the topics that are focussed on in this book and in the number of ways to solve a certain problem or dilemma.
Because of this, the book is suited for beginners as well as advanced users.
By the time you have finished this book (it will take a lot of time!) you will be a beginner/intermediate Delphi user no more! This is not a book with text followed by long listings, but rather text with screenshots and only those parts of the listing that are relevant.
This way, the source is build up while you're reading the text, not afterwards (the complete source code is on CD-ROM, including many other tools and sources).
