Praenumeration

Pattern description

Praenumeration was an early form of the subscription business model. It was a common business practice in the 18th century book trade in Germany. The publisher offered to sell a book that was planned but had not yet been printed, usually at a discount, so as to cover their costs in advance. The business practice was particularly common with magazines, helping to determine in advance how many subscribers there would be.
