This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

The prehistoric civic-ceremonial center of Tibes is located on the southern coast of Puerto Rico, just north of the modern coastal city of Ponce. This volume examines the geophysical, paleoethnobotanical, faunal, lithics, base rock, osteology, bone chemistry and nutrition, social landscape, and ceremonial constructs employed at Tibes.

This volume updates the original scientific survey of Puerto Rico and the US Virgin Islands, which was begun by the New York Academy of Sciences in 1913. Many aspects of natural history - geology, paleobotany, plant ecology, herpetology, ornithology, insect taxonomy, archaeology - are covered. Each paper provides a brief historical survey and a mention of future research opportunities in the field.
