When we reviewed the MARC records for June 2019, we found that a number of Polish titles were given the code of POLIAF - Political fiction, rather than POLSAF - Polish fiction. We've corrected the ones we found in this set of files, but it is possible that we missed some either in this file or earlier files. If you see a stray entry for Political Fiction on a Polish title, that's probably where it came from. Just remove the Political fiction subject if it is not appropriate to the title.
