“A library, no mater how humble or grand, is a series of sacred gateways. You pass through them and leave your own city behind; you journey through time and space; and for a little while, you escape the confines of your own circumstances. Each of us who are readers gets to live through a multiplicity of eras; we get to tiptoe through, to borrow Jorge Luis Borge’s phrase, ‘a growing, dizzying net of divergent, convergent, and parallel times.”
