Hi Rainer - It's a bit confusing, but strictly speaking, these two subjects are different, even though to our eye they seem the same:
Detective and mystery stories [x] Mystery and detective stories [x] Different in the sense that the search can't recognize those 2 different phrases as similar or same. (At least our search doesn't do that sort of thing yet...) There are all sorts of tiny variations in the way people use subject headings. Perhaps the challenge becomes working out that similarity I mentioned. > Finally, in the ol_dump_works_2011-03-31.txt file, what subject level > is contained there? I'm not quite sure what you mean by "subject level," but hopefully, the dump for Works in the system also contains subject information, which Open Library attaches to the Work level. (Many of our edition records also have subject information too, although that's not surfaced in the display. We made the decision that subjects were most suited to the overall Work level of something, since any manifestation of that Work would presumably be about the same thing.)
