I've always wondered which are best to use in combination. What I wonder about even more is how Calibre decides which information to use when there is conflicting information (descriptions from different sites, tags, etc.) i.e. what sites get priority. I see where it is possible to set priorities for covers, but what of metadata? Does calibre just 1) use the first it reaches and quit searching for that particular element, 2) use the last found, or 3) combine multiple sources?
