Welcome to the U.S. Geological Survey Libraries Program document delivery using ILLiad. We will check to see if the material you request is held by the USGS Libraries system. If it is available, we will either lend the item or provide an electronic copy to you. If it is not held within the USGS Libraries system, we will attempt to obtain it through interlibrary loan.
If you have general questions about library services or wish to request a literature search, please use the Ask A Librarian form.
