X. Недостаток у этого сборника, по сути, только один - полное отсутствие какой-либо сортировки. Ни по степени "продвинутости", ни по тематике.

For anyone on the English spectrum, Mr. Zhukovsky stated:
"The one part missing from this list is the absence of any kind of sorting order. Not by subject or by level (of competency)."

FYI. This is an approximate translation... I noticed that I have a hard time doing technical reading in Russian, it's both hard for me to understand and funny many times.
