We have the Ebsco database GreenFile listed on our Databases page because a few years back we learned that we had (free?) access to it. At the time it was my understanding that it was only citations, so I never promoted it too heavily. However, I taught an Environmental special topics English II yesterday, and discovered that there is definitely a good amount of full-text available through GreenFile. My guess is that it links to content available in other Ebsco databases, and ScienceDirect through the Linked Full Text that we see in Academic Search Premier. Just something to keep in mind for those researching environmental issues - this database may be more useful even to English I's than we (or maybe just I) initially thought!
