Searching TGIF

Introduction

The Turfgrass Information File (TGIF) database provides bibliographic and descriptive records of all types of works related to turfgrass culture. TGIF was established in 1983 by the United States Golf Association (USGA) Turfgrass Research Committee and the Michigan State University Libraries, and is now maintained by the Turfgrass Information Center, a division of MSU Libraries. The ultimate goal of TGIF is to provide access to all published materials reporting on aspects of turfgrass and its maintenance.

TGIF indexes a wide range of materials including journals, monographs, fact sheets and pamphlets, images, and web documents. Most records in TGIF contain informative abstracts; some contain full text or are linked to web-accessible full text. Records in TGIF are indexed using controlled vocabulary from the Turfgrass Thesaurus, produced by the Turfgrass Information Center, with additional identifiers where needed.

At the present time, online access to the TGIF database is fee-based, dependent on academic, professional organization, or corporate affiliation, with access available to individuals who meet qualifying criteria. Check to see if you have access to TGIF already! One future objective of the TIC Endowment is to make access free to all.
