Dialog Finder Files: Don't Forget the Bluesheets (File 415)

Dialog Bluesheets (File 415) are written guides for every database on the Dialog service. However, it is also a Finder File on Dialog that can be used to search for databases with appropriately indexed fields.

Consider the example where you need to identify newswires to develop Alert strategies that cover a specific industry classification code, such as the Standard Industrial Classification (SIC) code:
