The owner of the library is not he who holds a legal title to it, having bought and paid for it. Anyone and everyone is owner of the library who can read the same through all the varieties of tongues and subjects and styles, and in whom they enter with ease and take residence and force toward paternity and maternity, and make supple and powerful and rich and large.

Walt Whitman (1819-1892) American poet

Leaves of Grass, Preface (1855)
