Some more results, some of which _should_ match:
Alexievich, Svetlana - Second-Hand Time == Aleksievich, Svetlana - Second-hand time (96%)
Bennett, Sj - Murder Most Royal == Bennett, S. J. - Murder most royal (95%)
Bridge, Ann - The Lighthearted Quest == Bridge, Ann - The Light-Hearted Quest (84%)
Craven, Mike - The Puppet Show == Craven, M. W. - The puppet show (92%)
Davies, Robertson - Salterton Trilogy Omnibus == Davies, Robertson - The Salterton trilogy (94%, though I think this is reasonable)
Feynman, Richard P. & Leighton, Robert B. & Sands, Matthew - Six Easy Pieces: Essentials of Physics Explained by Its Most Brilliant Teacher == Feynman, Richard Phillips - Six easy pieces (87%, presumably because LT returns only 1 author)
Indridason, Arnaldur - Jar City: A Reykjavi*k Thriller == Arnaldur Indrišason - Jar City (77%)
Joad, Cyril Edwin Mitchinson - Guide to Philosophy == Joad, C. E. M. - Guide to philosophy (89%)
I thought there were some more non-matches, but maybe I was mistaken. Anyway, far more importantly, all the 100% matches are correct. Those were by far the largest category in my list
