Editorial contact
Publisher: Christian Zieschank. For postal correspondence, use the address in the legal notice. Both channels can be used for editorial, privacy and rights enquiries.
Make a correction easy to check
Include the article URL, the statement in question and a primary source where possible. Tell us whether the issue concerns the historical report or a later update. A correction can change the text or add context without rewriting the original publication date.
Images and other protected material
Identify the image or passage, the page where it appears and your relationship to the work. Our rights-enquiry page explains what helps us locate and assess the material. You do not need to send confidential account details to report a problem.
Privacy requests
Describe the data or correspondence your request concerns. We may need proportionate information to locate it and verify the request. Do not attach an identity document without first agreeing a suitable method. Read the correspondence privacy information before sending personal information.
What this contact channel cannot do
We cannot recover a wallet, reverse a blockchain transaction, access an exchange account or provide personalised trading instructions. An email to the publisher is not an order to buy, sell or move funds.
