"The appeal of observing double stars is the fun of measuring a difficult or long-neglected pair, and the fact that your data become part of a progression of measurements spanning over two centuries - data that may be combined with measures made long before you were born and used by someone long after you're gone."

William I. Hartkopf (in JDSO Vol. 6 Nr. 1, 2010)
