This book includes materials in many languages, as indicated in the 546:

546 __ ǂa Predominately in Ukrainian with articles
    also in English, French, German, Polish, and Russian.

Its Lang fixed field is encoded for Ukrainian (as that is the predominant language) but other languages are encoded in MARC 041. The old standard for this field was to concatenate all of the three letter codes in one subfield, like:

041 0_ ǂa ukrengfregerpolrus

But now each language gets its own subfield:

041 0_ ǂa ukr ǂa eng ǂa fre ǂa ger ǂa pol ǂa rus
