Thema subject finder
Thema is the book trade's international subject scheme. IngramSpark asks for Thema subjects when you set up a title, and says they're required in some countries for booksellers to buy your book. Search in plain words ("cosy mystery", "space opera") or browse, check where each code sits, and pick a main subject plus any that also fit.
Your codes
Thema subject codes are © EDItEUR, used unchanged under the EDItEUR licence. . For EDItEUR's full guidance on choosing codes, see their website.
Choosing well
Put the code that fits best first: that's your main subject. Add a few more only if they really apply. Qualifiers add detail that isn't a subject, like where or when the story is set, or the age group. Read EDItEUR's notes on a code before you use it: they say what each one is for.
What about BISAC?
BISAC, the US scheme IngramSpark also asks for, isn't here: its owner, the Book Industry Study Group, doesn't allow its list to be reproduced without permission. Look BISAC codes up free on BISG's own site.
