Why can't Google and other search engines find many articles useful for college-level research?
There are two reasons why Web search engines are unable to find many of the journal, magazine and newspaper articles available in the library's subscription databases:
1. They are locked behind publisher firewalls that block the “crawler� programs used by search engines to gather information about Web pages so that they can be found by their users.
2. The articles in many databases and Web sites accessible only by paid subscription do not have permanent URLs. Instead, URLs that include information about the password used to access the database/site or other information are generated each time a user views an article. These URLs expire when the user logs out and cannot be reused. Search engines are generally only capable of recording and pointing users to stable URLs.
The vast amount of information available in the so-called “invisible Web� (Web content that cannot be found by search engines) cannot be located directly by users using Google, Yahoo and similar sites at present.

I think it might be helpful - at least for users with a modicum of tech knowledge - to explain why Google "only goes so far". I slapped together the page below to answer a question that comes up fairly frequently in my online instruction sessions:

Google Accelerator and Library Resources
Google Web Accelerator (GWA) is a product from Google Labs that uses the Google network to allow one to surf the Web faster than before. This sounds like a good idea at first. Recently, staff in the University Libraries have discovered a downside to using Google Web Accelerator while using library-licensed resources such as electronic journals and online databases.
GWA creates a dynamic IP address for any of its users within the Google IP range. Therefore, if you are trying to access an e-journal via GWA, it will appear to the journal provider that you are coming to this resource from Google and not from the University of Minnesota's IP range. Consequently, you'll be denied entry into this library-licensed resource.
According to the GWA's FAQ, there are ways to disable GWA or to tell it not to "accelerate" a particular website, but in practice we've found this to be problematic. For the near future, we recommend not using GWA when using the University Libraries' licensed resources. / note from Lisa McGuire in BioMed Library
