This iOS app can download and display eBooks of Graph Theory
in all available editions, past present and future, and in all
languages. There are currently editions in English, German, Chinese,
Japanese and Russian.
Once you have installed the app, which is free for all iOS devices,
you can immediately try out a sample which displays one
chapter. The full iOS eBooks are also free on iPhones, so that you can test them there in full; on iPads they
become available as in-app purchases. The purchase of the current
edition in a given language also entitles you to subsequent free
downloads of all other editions - past, present and future - in that
language.
Each iOS eBook comes in high-quality searchable PDF; the same that
was used to produce the corresponding print edition. The cross-references in the text and in the margins
of the English and the German editions are active links: tap on the
"3.1" in a reference to Lemma 3.1 to be taken to that lemma.
The iOS app also offers a "pro" upgrade for in-app purchase
(also free, and automatically installed, on iPhones), which can be
annotated: you can scribble in the margins, highlight text, or add
boxes for typed comments. These annotations can be saved in your
iCloud and synchronized with any other iOS device you may have. The underlying book is still the standard eBook, however: this is not the Professional edition of the book, which includes hints for the exercises and is intended for professional mathematicians.
iOS eBooks, either standard or pro, cannot be printed. If
this is important to you, you can buy the Professional
edition, which can be both printed and annotated (but
not synchronized via iCloud). The Professional edition also comes
with free updates to future editions.
The price for the eBook edition is the same in both formats,
Standard eBook and iOS app.
