I would give 5 stars to Russell's essays but 3 stars to this edition.
This edition contains most of the important/technical papers that russel wrote & are still worth reading for any serious philosophy student. The editor did a great job at selection but his snobbish introductory essays prefacing each russell essay is a complete waste of space & (your) time. The editor should have but didn't bother to update the logical symbols in the 1st russell essay, 'logic of relations', with the result that it would be incomprehensible even to people trained in symbolic logic.
'philosophy of logical atomism', for me anyway, helps me understand wittgenstein's Tractatus, which was otherwise incomprehsible to me.
I didn't make it through 'on denoting'. Who would really care about this important but by now mainly historical essay if you have already learned quantification theory & description theory?

This book reproduces Russell's famous article 'On Denoting' that appeared in "Mind" in 1905. It provides the earliest account of his theory of descriptions that was later developed in principia mathematica and 'improved' by W.V Quine. (It is however, a dog to read!) It is truly a fundamental work in logical analysis and I recommend it to you all.
