Multiple States:

• Journal of Extension (JOE) — 1970 - present. JOE is the official refereed journal of the U.S. Cooperative Extension System. It seeks to expand and update the research and knowledge base for Extension professionals and other adult educators to improve their effectiveness.
• PlantFacts — horticulture and crop science information from 46 different colleges, universities, and government institutions across the United States and Canada. This searchable site run by the Department of Horticulture and Crop Science, The Ohio State University provides access to over 260,000 pages of Extension fact sheets and bulletins from every land-grant university in the U.S. and several government institutions across Canada. Try this resource even for non-plant research queries as their "plant" filter is porous.
• Extension Information about Alternatives — links to Extension Guidesheets prepared by extension agents around the country, organized by topic. Provided by the Missouri Alternatives Center and the University of Missouri-Columbia.
• Extension Forestry — "Best Extension Forestry Sites in the US" compiled by About.com, which provides links to many state sites which include publications.

Individual States:

• Survey of Digitized Historic State Agricultural Publications — This spreadsheet is an on-going inventory of digitized state agricultural publication series. Links to publication series for each state and U.S. territory are listed on a separate tab. It is the result of an AgNIC Working Group led by Rob McGeachin from Texas A&M. If you would like to contribute to this project, email Rob at r-mcgeachin@library.tamu.edu
