You can read this book by clicking on the image above or this link.
In this book, references are made in the notes with links on the internet. Albelli does not (yet) have the possibility to access the links from the text.
The following is the solution to make the links easily accessible.
On my website www.vanenos.com go to the English part and the page about The Crack. There is a download of a pdf with all links with reference to the page in the book.
So if you download the pdf and put it on your computer desktop, you can access the links right away, when reading the book.
