GoogleScholar and subscription Electronic Databases

I have had occasion over this semester to meet with Jody Bailey, our reference Librarian at the UTA Library. In addition to having a MLS, she also has an MA in Linguistics. And she is a tech whiz. Another class (Pragmatics) had an entire class session with Jody at the Library, and she covered the subject of the varied databases and other research tools available thorough the Library ... It is an amazing array.
One of the most amazing things to have come out of that session was, certainly, her tour through the various subject searches across databases, and the search strategies she set up in individual ones. She also discussed how the subscriptions to these databases work: there are fare more out there than UTA subscribes to; there are levels of subscription within a particular database, say, LLBA, or MLA, or EBSCO, or ERIC ...; but most stunningly was how expensive subscriptions to these little suckers can be.
Also of note was her endorsement of GoogleScholar as a worthy research tool - because it will give info on whether, and how many times an article has been cited, it will allow you to play with search terms and strings, it will/may find quality articles for you (not everything coming off the sub databases is guaranteed to be perfect, either), and, best of all, it is free to use and many of the articles cited are available free in .pdf format!
It is its basic quality plus this last item - being free to use - that interests me. Even if we are doing service learning tutoring and teaching at a program with a limited budget, by virtue of our UTA association, we do have access to all of this wonderful stuff, plus InterLibrary Loan and TexCat for free. Our program with the limited budget cannot affored these services, but they sure can - if they have computers - utilize GoogleScholar.
It was good to know that Jody thought well enough of GS to discuss it and analyze its searching capabilities and functions.

BTW, if you have not had an opportunity to work with Jody and benefit from her help and knowledge on a research project, you really owe it to yourself to do so.
