The Amiga Guru Book is probably the ultimate programming reference for the Amiga. [...] The level of accuracy and detail maintained throughout the book is amazing. [...] There have been many other attempts to write reference books for the Amiga, but not a single one matches the Amiga Guru Book in the richness of detail and depth of background. [...] Along with the ROM Kernel Manuals, The Amiga Guru Book is one of the essential reference works every serious Amiga programmer should own. [...] if you need in-depth information on the workings and usage of the OS and especially AmigaDOS, this book is a must. With more than 700 pages, it sets the new standard for quality in Amiga references. [...] 5 stars out of 5.
