Oops... only verified contributors can edit the database

Thank you for taking an interest in improving the quality and/or completeness of our database!
Nothing personal, but we want to monitor the quality of our data as closely as possible… which is why we reserve direct  access to the database to a few professionals.

So please enter your suggestion in the form below.
We need the ProducerID in order to identify the producer af whom we should edit the data.
Please be as precise as possible in stating your information.
We do not include data without a precise reference to their source. So please include:
– in case of an online source: the complete url (preferably the permalink)
– in case of a printed source: 
   – if an established secondary source (the Liggeren, etc.): name of the publication, page, possibly location (footnote, etc.)
   – in all other casess, please add author(s) and year of publication

We will send you our feedback once your contribution has been processed.
