Hi, The MARC->MODS mapping takes 008/34 BK (code a) to "biography" rather than "autobiography". (MODS->MARC takes "autobiography" to 008/34 BK code a, however.) "game" is mapped to 008/26 CF (code g) only, but it also corresponds to 008/33 MP (code n) and 008/33 VM (code g). No mapping is given for "multivolume monograph." How does it differ from "series"? No mapping is given for "online system or service," but it should be 008/26 CF (code j). There is no term in marcgt for 008/24 BK (code u) and 008/24 SE (code u), nor for 008/21 SE (code #). --Andy
