У истоков мира : Русские этиологические сказки и легенды / составление и комментарии О.В. Беловой, Г.И. Кабаковой = At the origins of the world : Russian etiological tales and legends / compiled and commented by O.V. Belova, G.I. Kabakova. (OCLC 867778645)
This book had a full parallel title page, which was helpful, but meant that I had to also consult the ISBD standard.
RDA only specifies content: which elements to record, and in this case, the order of all instances of a specific element; for example, RDA 220.127.116.11 talks about all parallel statements of responsibility. We are doing our description in ISBD (display), so must check that standard for rules on ordering and punctuating the full paragraph.
