Reply #4: "low retrieval with high pertinence"

[midnight]

What you need what we in library circles refer to as low retrieval with high pertinence. That is to say, you only get a small amount of information that is the most relevant information in satisfaction of your information needs rather than getting voluminous irrelevant information that you can't use which doesn't have the sufficient depth and scope. That's why you need a library that has professional collection development and collection maintenance that mirrors the needs of the community as determined by a community analysis conducted by professional library staff.
