prize7-4, Exercise 2: What printing changed

Model answer (check the details):

Three changes:
1. Identical copies: many people could hold the same map, so discussion and comparison became possible.
2. Correction: a plate could be revised, so a new state of the map could show new discoveries.
3. Public ownership: merchants, officials and educated readers could buy maps, not only rulers and clergy.

One more (optional): a publisher's name and sources on the sheet made maps open to criticism.

What stayed the same: a map was still the work of someone choosing what to include, and it still copied earlier maps, sometimes including their errors. Decoration, authority and commercial interest still shaped content.
