Weeds Identification documents in PDF and other formats that can be downloaded and viewed or printed on your computer system, digitial reader, etc.. Mostly FREE!

Many of the Weed Identification documents at Ergonica can also be found on other websites through authors identified in each item's description. Since original publishers often change their websites and URLs, making the orignal source unavailable, Ergonica copies the documents and publishes them as archived documents for the long term. Original URLs are not presented for the same reason. Document keywords at Ergonica are derived and offered through Ergonica research, even though original publishers often do not make many keywords available. This means that your keyword searches for locations, publishers, types of weeds, etc., may be more productive here at the Ergonica Catalog than on the Internet in general through any search engine. This is a public service that unveils some information that is otherwise hidden from Web searches, either through neglect, economic considerations or intent. Use the search tool above to enter any keywords relevant to your information interests.
