The First 50 Years of Hebrew Printing

When printing first began, i imagine it was still very expensive. Do we have any idea of what were the books that jews gravitating towards? O looking at the first 50 years of hebrew print is a really good way to to start to think about that. What do you think was the first book that was ever printed? If you would just guess out of a had if you're printing hebrew books, what would you print? The hamish, the bible. But that's accessible in every shill, so you don't need that.
