What is the full title and who the author of the science fiction short
story from the 1950's or early '60s that used the word "liebury"
(perhaps in the title), an alien misreconstruction of "library"
thought to refer to the ocean spanning building that housed our solar
systems knowledge collection before it was moved to the asteroid belt.
The story is presented as a field report from an investigative
archeological team. The civilization collapsed when all real
knowledge, Rx, was misreferenced amidst the still exponentially
growing indices, Ix, bibliographies, Bx, and IxBx, BxIx. that refer to
it, resulting in circular references to references. Introduced
concepts of nudged and notched photon as storage mechanisms.
