fantastic
This is a fantastic book of all you ever wanted to know about weeds! I am sure that the editorial information already written tells you far more about the specs of the book than I would ever wish to type. Weeds are so diverse, and there is so much to know---what exactly IS a weed? This book is fantastic for its huge amount of important minutae and its vast amount of time devoted to research. Fascinating, so fascinating. There is so much important info here on all kinds of plants. ... Read more

The Overleases' compendium records the continuing expansion of weeds-aggressive plants that can move into an available habitat-across Indiana. ... Read more

A very highly recommended addition to academic library Environmental Studies reference collections
Profusely illustrated with Indiana maps detailing and illustrating the text, "100 Years Of Change In The Distribution Of Common Indiana Weeds" quite literally covers a century of horticultural and environmental history within the state of Indiana as pertaining to the establishment, distribution, and movement of weeds common to the area. Beginning with an informed and informative introduction to the subject, the co-authors, William and Edith Overlease, provide a 202-page compilation of 'Common Indiana Weeds' and their distribution within the state. A 46-page descriptive presentation of Rare and Uncommon Weeds and their distribution concludes this seminal treatise, along with an extended Index. An impressive work of impeccably methodical scholarship, "100 Years Of Change In The Distribution Of Common Indiana Weeds" is accompanied by a CD allowing for easy reproduction of the various charts and lists. A very highly recommended addition to academic library Environmental Studies reference collections, "100 Years Of Change In The Distribution Of Common Indiana Weeds" could well serve as a template for similar studies in all of the other American states and Canadian provinces. ...

Product Description
Weeds are usually known to farmers and the general public by their common names. These names, which are obviously easier to remember than their corresponding Latin or Linnean names are also frequently used in non-scientific technical literature. The fact that one species may have several common names, while in some cases one name can apply to several species, creates much ambiguity and confusion - especially for those engaged in comparative studies or wishing to incorporate research done in other countries into their own work, as well as for translators working in this field.

Although some European countries have attempted to solve this problem by producing official or semiofficial lists in which one common name is given for each species, some of these lists have only a limited circulation while not all authorities from the different countries are in agreement over which species should be classified as weeds.

The Education Committee of the European Weed Research Society has gathered together national lists and attempted to remedy their deficiencies. The result is this dictionary - about 1,000 plant species have been classified giving the common name for each, where it exists, in all of the major European languages.

An additional feature of the dictionary is that the importance of particular species as weeds in the different regions of Europe has been estimated. This multilingual dictionary should thus prove invaluable to all weed scientists, botanists, field ecologists, translators of technical literature and those involved in the international agrochemical industry.
