Weekends are the time to do errands. The bookshelves were overflowing and it was time to move some of the books down into the basement "archive." The Encyclopaedia took the lottery and down it went. All the knowledge that fits into 30 volumes; unreferenced for years; replaced by the infinity of the Internet: Wikipedia. Published in 1984, it never changed. An information snapshot. It may hold some interest, just the same as a snapshot from 1984 might.
