A catalogue of things that do not exist

Holdings read: 678
Holdings total: indeterminate
Floors surveyed: none completely

The Tower catalogues subjects that do not exist. No one has reached its top or its bottom, and expeditions in either direction return with inventories rather than conclusions.

Search for anything. The catalogue will list holdings on it. Those holdings can then be read, at which point they were always there.

The catalogue is comprehensive. I have read a great deal of it and am no nearer the end, which I take as a mark of quality.
