The first thing I did was an ANNIE search for 'environment*' LIMITED to Periodicals, and that netted me 77. 77 what? Some of them are slightly bogus if we think we want "Environmental Studies", but it's good to look at a slightly larger set.
Here's the set in 'short' form. A fair number of them have to do with Environmental Law...
...and of course there's also the question of what's not on the list. Many of the journals in the realm of climate change are clearly candidates for relevance, and there are others lurking in the JSTOR archive in various categories, and elsewhere (like Economic Geology). It's very much a matter of how one conceives the boundaries of 'Environmental Studies'.
And then there are journals we don't have but probably should. A couple of years ago I did some searching and came up with candidates including Ambio, Critical Reviews in Environmental Science and Technology, Environmental and Ecological Statistics, Environmental Reviews, Environmental Science and Technology, Journal of Applied Ecology, Journal of Environment and Development, Journal of Environmental Engineering, The Environmentalist...
My own bias is toward a definition of "Environmental Studies" based in the sciences, and there's a lot I'm just beginning to consider about how to improve access to what we have, how to meld the Science definitions with the C-School definitions, how to approach what librarians call "collection development" more systematically, how to bring stuff to the attention of those who might use it if they knew about it...
Back to Annie keyword searches, and looking at periodicals AND books AND whatever other material types we can distinguish:
'environmental' gets 7927, 'environmentalism' gets 220, 'environmental studies' gets 38 --and we might ask of that set ?how well does it represent what you are concerned with? How well does this set of results for that term map to what you think of as "Environmental Studies"?
The great problem of information access for Environmental Studies is that materials are spread all over the library, and mapping their distribution is a non-trivial task. Just try a search for 'environm*' as a Subject (gets 2863... each with one or more books). 'environmental' gets 2830... and 'environmentalism' gets 34...
And this is just looking at what we have in a moderately good college library.
So clearly you face an enormous terminological problem in finding the materials you think you need, let alone finding what you actually need... Accordingly, I need to show you some of the possibilities of the present moment, noting as I do so that the landscape of information changes constantly --indeed, we have some tools today that weren't available two weeks ago, and who knows what next month will bring.
Several headings:
The Resources for Environmental Studies page (accessible from the Science Library's page) offers links to many relevant tools. The ones I want to spend time on are mostly under 'Indexes and Databases'
