Cárok és kalandorok : a “zavaros időszak” története / Szvák Gyula. (OCLC #922582189)
Several booksellers described this book as being in the “rainbow” series (“Szivárvány”) but I didn’t find that word on the piece anywhere, just a rainbow on the cover. I included a series statement for it so that it would be searchable:
490 0_ ǂa [Szivárvány]
but left it untraced, and also put it in brackets (following RDA 2.2.4) because I got the wording from somewhere other than the piece itself.
