If nobody else can read the numbers, they are just as useless as fugitive
ones.  And it happens - we have numbers on things in our collection that
are virtually unreadable due to poor writing, and others that are readable
but can be read in more than one way, resulting in much lost time and in
the risk of lost information about the item.  Sometimes I think
disappearing ink would have been a mercy!
