AGRN 479 - Weed Science Information Guide: Photographs and Images

The US Department of Agriculture's Agricultural Research Services has developed an Image Library. Because USDA is a government agency, their images are in the public domain, and can be re-used without paying a fee. Images on this site can be used if credit is given to the photographer.

This site can be used to search for information on a specific topic developed by U.S. Government agencies. It is also possible to narrow the search results to a type of resource, such as images. Government publications, including photos in government publications, and photos taken by government employees are not copyrighted, so they can be used in presentations, but remember to cite your source! To find images, search for a topic (e.g. Black Footed Ferret) and then narrow the search results by choosing to view only images.

A consortium of natural history and botanical libraries is cooperatively digitizing older publications related to biology, biodiversity and natural so that they can be freely viewed and used online. The library can be searched or browsed by title, author or subject. Images from the publications can be used in publications, but remember to cite the source!
