Example:

ISBN (Complete work) = 978-3-443-01060-7 [currently not enabled]
Place Published = Stuttgart
Publisher = Borntraeger

PhycoBank:
Editors are needed in PhycoBank for proper citation, e.g. of Identification books (like Süßwasserflora von Mitteleuropa) including nomenclatural acts.

Taxonomic Projects:
If users need to cite a Print series for example as a sec. reference, Editors and Edition would get lost, without referencing all single volumes. ISBN for the complete work would be nice to have but is not essential.

Vaadin & TaxEditor should be harmonized.
