This is a 199-page book containing Dilbert cartoons which focus on power and its abuse. The strips, which were originally published between 1997 and 2011, are in black and white except for the Sunday strips, which are in colour.
For some reason, the chronological presentation of these strips are interspersed with pages of a series of strips from late 2008 to late 2009, presented on a blue-green background. This means that you will be reading cartoons from 1998, then from 2008, then from 1998 again. There is also duplication between these two series, as the two cartoons on page 167 are duplicated on pages 115 and 131.
As this is a compilation, I only started reading new strips from page 101 onwards (apart from the strips presented on the blue-green background). Therefore, while this may be good value for someone who has not read much Dilbert before, for those who collect these books, you will have already read around half of the book.
If you are a new collector, I would suggest starting with Dilbert 2.0: 20 Years of Dilbert
instead. If you have already got a lot of Dilbert, I would not suggest buying this book. It's a shame there are a lot of previously released comics.
