Our understanding of how rarity and pricing interact in the collectible paper field continues to become clearer as the number of appearances and their outcomes are added to our Rare Book Transaction History. Today, April 30th, is the first time our total transactions have reached 16 million, or to be exact 16,005,571. Does it matter? Yes.
Books (and all forms of collectible paper) in time turn into numbers and we study how to convert this data into market clarity. Today’s big numbers suggest broad interest in the category.
Both bibliophiles and tire-kickers gain from market clarity and we’re mesmerized ourselves. By the time we reach 17 million records we expect to convert this market data into new approaches to the data we have.
