External sources of information: the kinds of services and facilities offered and criteria for evaluation

Every library or information service is at bottom wholly dependent on sources of information external to it. It must acquire from outside all the documentary information that it transmits to users. But at this conference we are thinking more particularly of external agencies that provide material or services that might and could legitimately be provided internally.
