Speaking from personal experience, I usually see several results for any search. Granted, there's a big selection bias there, but 20% seems way too small.

- sgillen 7y agoTo be fair for textbooks at least I often see several results but often of different editions (1x edition 1, 2x edition 2, 1x edition 3 etc.). In some cases I think it's worthwhile keeping the different additions around, unless it becomes a huge burden.
