This one jumped out at us this morning because, at first glance, it looks correct. It can be found on the B list, or high probability errors that might be found in an online catalog. When you go to correct it, you will need to decide if the intended word was completion or competition. When we checked Worldcat this morning, we found that this was high probability indeed with nearly 150 hits. In looking over the first screen, it appears that "Competition" was the likely intended target in most of these.
