Adding the author relator term to this record’s 100 field was slightly tricky: it started as:

100 1_ ǂa Lee, Vladimir Ya.

but that period at the end was not added to the end of the 100; it is part of the access point itself. The author was born in Russian Federation, and Ya (Я) appears to be his middle initial, so we keep its period accordingly:

100 1_ ǂa Lee, Vladimir Ya., ǂe author.
