In carrying out my invention, I find that place
markers I0 and 20 that are about two and one
half inches square are Well adapted for general
use with books of small and medium size, the
markers 30 and 40 being correspondingly larger
for uses making said larger place markers de
sirable. The small angle extension slits for place
markers made of thin sheet material may be
about one-sixteenth of an' inch long. and for
place markers of thick sheet material they may
be correspondingly longer. In any event, said

angle extension slits should be only long enough
