What are Keyfiles?
Keyfiles are in-depth data sheets providing detailed technical information for a selection of
relevant products manufactured or distributed by particular companies. These are specifically
authored to assist the specifier in product selection and include product descriptions and photographs.
These data sheets are placed in Keyfile Libraries. More information on the Office Library Service is
available from
