In 1961, civil activist Reinhard Strecker wrote a book, "Hans Globke - File Extracts, documents based on Strecker's research in Polish and Czech archives", which was published by the Bertelsmann publishing house Rütten & Loening. Globke tried to block further publication in court with an interim injunction. The BND, under the leadership of the former Wehrmacht General Reinhard Gehlen, spent 50,000 marks trying to take the book off the market. When a court then discovered two minor mistakes (the publisher had caused one of them by abbreviation) and imposed a restraining order, Bertelsmann caved in, and cancelled a new edition of the book. The government is thought by historians to have threatened that no official agency would have acquired a book from the publisher again.
