In celebration of the release of the revised 5th edition Glossary of Geology for the Kindle and Nook platforms, the American Geosciences Institute (AGI) has started a free GeoWord of the Day service.
The GeoWord of the Day is a fun and convenient way to learn a new geoscience term every day. Each morning (US ET) the service will highlight a new word or term featured in the Glossary of Geology, ensuring daily authoritative terms and definitions for years to come. Users may choose to receive the GeoWord of Day directly through email by subscribing online at http://www.agiweb.org/word/.
