Informative, but slightly longer than it needed to be to convey the relevant information. It contained a lot of lists which would grow outdated over time (for example, comparisons and evaluations of worm composters which were available at the time of publishing). References were provided at the end, but not linked to from the text, which made some of the claimed benefits of vermiculture a little less credible. The book was slightly too evangelical at times to be credible either.
