The best I can come up with is embossing stamps.  They make an
impression, but without ink.  It would be similar to the stamps that
officials use to notarize documents.  I've seen such ownership stamps on
maps and books.  They once were more common than nowadays.

They don't capture the eye as much as printed stamps using ink, so that
the effacing of the page is not as obtrusive.

     Lately I've been reading about map library practices for marking maps,
     particularly rare and valuable maps.  Once in a while in the literature
     there is a mention of invisible property stamps that only show up in
     certain lighting.



     I haven't met anyone who uses this kind of stamp (or maybe I did and it
     is a closely guarded secret!).



     Anybody have any comments on this practice?
