Database - The Turfgrass Information File - Search Now!
Materials indexed in the TGIF database include articles from peer reviewed publications, technical reports and conference proceedings, trade and professional publications, local professional newsletters, and popular magazines as well as monographs, theses and dissertations, fact sheets and brochures, software, and web documents. TGIF indexes materials from government, college/university, professional organization, and private publishers. Coverage emphasizes English-language materials but does include coverage of non-English languages.
As of February 2015, there are over 250,000 records in TGIF, with a gradually increasing percentage of content linked to full-text sources. About 12,000 new records are added every year, with over 50% including full-text or linking to full-text. Ultimately, the Turfgrass Information Center will offer online access to the complete publication history of turf science, reaching back into the late 19th century (or perhaps before) through TGIF. In fact, much of this older material is already listed in TGIF; for example, all USGA Green Section periodicals published since 1921 are now indexed and linked to full-text electronic versions from within TGIF!
The Turfgrass Information Center (TIC) and the continued expansion of TGIF have been supported by subscription and user fees, donations, and the MSU Libraries.
An Endowment Campaign is now underway to stabilize the long-term basis for the Center's efforts.We are actively seeking organizational, institutional, industry, and professional support for the Campaign.
TGIF Content (Scope - of - Coverage)
This model gives TIC the ability to slice the literature based on the
type of source it was published in. "Refereed" materials are
clearly the most important from a research perspective. They have passed
the process of peer review and revision, with traditional academic rigor.
"Report" materials are not refereed, but are research, often qualified
as "preliminary" or "incomplete." "Professional" sources are
those generally produced by Not-For-Profit corporations as communicative
for membership. "Proceedings" are usually from a specific conference,
and can include individual articles which might show up in any of the
other categories, except refereed. The Proceedings literature is very
unpredictable, uneven, and sometimes frustrating, but it is an important
category in the whole of the literature, particularly from 1950-1990. "Trade" sources
are generally commercial magazines, and are distributed widely within
the industry. "Newsletters"
are just that, mostly GCSAA affiliate productions. The "newsletters" vary
tremendously in their availability, size, and "usefulness" from the
perspective of TGIF. "Popular" publications are those intended
for a general public readership, outside the professional arena (if
you think these
are not important to your job, we think you are mistaken!). In addition,
there are "Miscellaneous" sources which complete the literature. This includes the increasingly important 'born digital' portion
of the literature, such as podcasts and video.
What is the significance and role of these categories or LEVELs? In TGIF, the LEVELs are searchable in and of themselves. If a searcher wants to see citations on a topic, but only those published in refereed sources, this can be done. Likewise, "categories" can be excluded wholesale from a search. If a searcher wanted articles on mole crickets, but only ones that were published in trade or professional magazines a practitioner might be likely to have on his/her shelf, this can be done. In the Guided Search, the LEVEL is easily specified by drop-down list. In "Power Search", specify LEVEL="category name", for instance LEVEL=REFEREED.
In the Power Search, a searcher could also restrict the search to a specific magazine, and/or a specific author, specific "types" of materials, and/or a specific year/years of publication. More details about searching in Power Search.
In producing TGIF, TIC monitors the turfgrass literature, regardless of sector, context, geography, or language. Thus, TGIF can produce excellent searches on transitional overseeding, cricket wicket preparation, kikuyu grass invasion, gray snow mold control, sod production in Florida, or variety trial results in German.
