This volume, nicely presented though it is, is largely a collection of lists. Much depends on which facet of the project you are interested in; the pharmacist will find plenty of interest in the painstaking research and detailed information; the synthetic chemist though will be disappointed. There are brief synopses of (selected) preparations and some literature references, but the majority of Dr. Shulgin's detailed practical procedures have been available for years in Pihkal. Similarly, the spectroscopic data is essentially confined to mass spec. which, although a powerful technique, has long been overshadowed by nmr. (Although in fairness, the latter technique was far less accessible when most of the syntheses were developed than it is today) .I hope that the likely intention mentioned in the text to provide the nmr data that was actually collected is carried out in any future publication(s). All in all, the book is a pleasure to look at, great for browsing and hopefully a taste of much more substantial things to come. But if you want practical detail then the internet, as in so many other areas of science, is the way to go.
The book is very useful if you just want a quick review of the literature on a particular compound. The mass spectra are also a welcomed addition as it's nice to have accompanying spectroscopic data if you come from a research background.
