According to Wiki,"An index card (or system card in Australian English) consists of heavy paper stock cut to standard size, used for recording and storing small amounts of discrete data. It was invented by Carl Linnaeus." Linnaeus, being famous for his contributions to taxonomy, is rarely associated with his invention of the index card, a "revolutionary" invention for managing data.
I often get side-tracked when web-surfing and discover many facts I might not have known (or even care to know) when looking for information on the Internet. Regarding index cards, I knew about the"heavy paper stock being cut to standard size" and that index cards are "used for recording small amounts of discrete data," but I did not know they were invented by Carl Linnaeus — nor, I must confess, had I thought much about their origin.
