Though most were about time travel,I liked the FogHorn and Our lady of the saurapods.Though Strata,didn't have anything to do with dinosaurs.But still a great book!

Contains excellent illustrations. The terminology and abbreviations may be confusing to some. Needs to be updated as some of the family nomenclature has been changed. I wouldn't recommend this for the average "what's this plant" person.

EXCELLENT first-book to reach for when needing proper scientific terminology. Does include some common names in the descriptions. Extremely detailed and uses extensive abbreviations. I used this book in Univ. of Idaho botany classes in the 1980's and still use it in my daily job now (year 2000). However, it does indeed need to be updated for current terminology and names, including lower-case spellings.

This botany key is used by University of Idaho's botany classes. It is still "the" book reached for by the professional in the work force. Afterall, what else is there that is so comprehensive? However, it is in need of revision due to changes in genus and specie names since its fifth printing of 1981.

The maps of this book are too difficult to read, and while there are numerous references to specific Pennsylvania counties, there is no map of the counties for which to refer. The subtitle, "and the Northeast" seems to have been an afterthought. Little attention is given to the region outside of Pennsylvania. Most disappointing are glaring omissions, such as the absence of the Tiger Salamander from the key to salamander larvae. The formatting of the text is unfriendly and it is difficult to quickly flip to a species account, as the headings are of the same font and set off very little from the rest of the text. The original morphometric data in the appendix is one nice feature of the book.

The Book is very good for identifing PA species. It contains a good set of color plates, a identication key and text describing the species. The text describing reproduction and habitat is also quite good. The downside of the book is the range maps. Inside of PA the author uses dots at specific locations, outside of Pa the author shades the area that the species occurs in. The specific location dots in PA are not complete. Overall I would recomend this book for people who wish to learn about and identify Pennsylvania's Reptiles and Amphibians.
