This WEB SITE edition will contains the first  480 plates of Schmidt's Diatom Atlas.
These are available for publication as more than 70 years have elapsed since the authors passing from this mortal coil.
Thus, their work, we believe, after diligent searching, is now in the public domain, according to E.U. copyright law.
