Read the following passage and answer the item that follows. Your answer to this item should be based on the passage only.

"A public library is not a warehouse for books, nor is it a reading room for those who already read well. Its holdings matter only in so far as somebody can reach them: the child who has no quiet corner at home, the applicant who needs a form and someone to explain it, the reader with no money for the volume and no other place to sit with it. A collection that is complete and closed serves nobody. A modest collection that is genuinely open serves everyone who walks in, and that, and not the size of the catalogue, is the measure of the institution."

Based on the above passage, which one of the following terms best expresses the ultimate purpose of the institution described?
