I've been pondering this for a while, as there are quite a number of series with the same names, but by different people. I'm thinking it might be best to establish some naming conventions.
The most common names tend to be "xxx Abridged", so I'm thinking for any duplicate series "xxx Abridged", all versions should be "xxx Abridged (by yyy)", or similarly if other style names end up duplicated.
I would also suggest any existing series which has the creators name in it be reformatted to keep everything in line.
Any feedback on this idea is appreciated
