In a session recently I used the analogy of being in a supermarket. You might have access to information about all sorts of products (via advertising say) but can only buy the products in the shop you are in.

I originally developed this as a way of explaining the difference between A&I databases and full text databases. A TV listings magazine gives information about shows on all channels (i.e. articles in all journals), but you can only watch the shows that are free or on channels you subscribe to (i.e. journals that are free or your library subscribes to). This can be broadened to the wider area of finding information on a topic by drawing distinctions between general resources like the Time Out film guide (Google - doesn't care what types of films/academic information you need) and the guide to greatest horror films (subject-specific, will give far more in-depth knowledge). Essentially, it's part of showing that depending on your particular need there are some resources that are better-suited than others. Still worried about not crediting these to the creators but they have been sent to me rather than the list so I think I need to respect their confidentiality. Perhaps I'll list all the contributors once the ideas start to dry up? Mark -- Academic Excellence at the Heart of Scotland.
