What is TEEAL?
TEEAL, or The Essential Electronic Agricultural Library, is a full-text and searchable database of articles from 200 high-quality research journals in agriculture and related sciences spanning several years. It arrives on an external hard drive that you can run on one computer workstation or make available to multiple computers via your local area network or intranet. For the past 10 years, TEEAL has been improving access at institutions with limited Internet time and/or financial resources. It is a searchable, offline, digital library which contains mainly agriculturally focused reference journals updated annually and delivered on the 1TB hard drive by Cornell University’s Mann Library. This non-profit digital library includes some of the most prestigious full-text agriculture journals that leading publishers have gifted to TEEAL users.
TEEAL is available for purchase at a low cost, and is solely for education and research in public and non-profit institutions in eligible-income countries. When you purchase TEEAL for the first time, you receive an external hard drive of journal content from 1993 through 2009. TEEAL is updated each year. Updates are shipped to current subscribers every December on a small set of DVDs.
How TEEAL works

TEEAL hosted on a local area network (you can also run it on a standalone computer)
TEEAL is delivered to you on a small external hard drive. Your shipment also includes a USB cable and a power cable, a setup guide, and pamphlets to help users get started. TEEAL is a Windows-based desktop application. Once it is installed on your computer, you can search for and retrieve full-text articles. You can run TEEAL on a single computer, or host the collection on a server and share it over a local network (see illustration above). See the hardware requirements for computers and servers. Please visit our Technical Support page to learn exactly how to set up TEEAL on a network. If you need help determining whether your network or server can host TEEAL, please email teeal@cornell.edu. It is strictly forbidden to provide access to TEEAL over the Internet.
