How many books could a copyist produce in 5 months?

The number of books a copyist could produce in 5 months depends on various factors, including the copyist's speed, the length and complexity of the books, and the working hours per day. Historically, a skilled copyist might have been able to copy one book every few weeks, translating to possibly 3 to 10 books in 5 months. However, this is highly variable and can differ significantly based on individual circumstances.
