Lectures and Essays (GA 7)
Heidegger collected
Vorträge und Aufsätze in 1954. He says in the foreword that the lectures and essays are arranged along a path.
The English translations (1960's/1970's) were divided and published in several books, alongside other essays and lectures.
I don't know why "
Was heißt Denken?" (1952) has not been translated. It is not the lecture course with the same title.
The pagination isn't exact. Sentences separated at the bottom of a page in the books have been reunited. Greek words in the translations have been un-Romanized when they appear in Greek in GA 7.
