A retired colleague is working on a database describing the fruits and
seeds of all families of seed plants, i.e. angiosperms and gymnosperms in
the tradional sense.  He is thinking about illustrating it with published
figures which are no longer under copywrite.

Does any TAXACOM reader know the exact year before which all printed works
no longer are under copywrite?
