Collection
50 Years of TOCS
2017 marks the 50th anniversary of the journal Theory of Computing Systems (TOCS). The two Editors-in-Chief of the journal at that time share some thoughts on this auspicious occasion. This celebratory collection is extraordinary in a number of ways. We have departed from our customary practice of publishing only refereed original research papers by inviting largely expository, unreviewed papers by several members of our excellent Editorial Board, on topics of their choosing. We hope that you enjoy the result.
