Developing a search strategy requires thinking about where to search as well as about the best terms to use.
Just like when you shop, sometimes your best choice will be going to a 'big box' store; other times you'll want a more specialized 'boutique.'

The library equivalents to a specialized 'boutique' store are the library catalogue or specialized databases.
