The collection for 1569 tells us that VD16 misses 4 out of 11 authors (36.4%). For both years, VD16 records 23 editions from 14 authors. The two collections suggest that VD16 misses at least 4 out of 18 authors (22.2%). This isn't an answer to the question of missing editions, but it does give us some interesting core samples to think about."#buchgeschichte
