CdV's and cabinet cards were made from negatives, which could be duplicated. There was degradation, however, each time they were used, so they had a limited shelf life.
Almost all Cdv's and cabinets have the photographer's name and contact information on the reverse, and it's not unusual to see "duplicates available upon request". But don't contact them now for copies, I think they may be out of business.
And woodcuts were made by engraving wooden blocks and then inking them, although it was probably a bit more complicated than that.
