About Thomas Kuhn's essay Reflections on my Critics I found two different refereces:
In The Stanford Encyclopedia of Philosophy it's reported as [1970c], see:
1970c, “Reflections on my Critics”, in Criticism and the Growth of Knowledge, I. Lakatos and A. Musgrave (eds.), London: Cambridge University Press: 231–78.
In a collection of Kuhn's essays (Dogma contro critica - Mondi possibili nella storia della scienza) I see that a quote from the above-mentioned essay is associated to Kuhn [1970b] instead than [1970c] (footnote134, p.335). On the other hand, on The Stanford Encyclopedia of Philosophy the [1970b] is associated to a different essay (Logic of Discovery or Psychology of Research?), see the following:
1970b, “Logic of Discovery or Psychology of Research?”, in Criticism and the Growth of Knowledge, edited by I. Lakatos and A. Musgrave, London: Cambridge University Press: 1–23.
I wonder whether one of the sources is incorrect (in particular, should I trust The Stanford Encyclopedia if Philosophy?) or if letters [1970a, 1970b, 1970c and so on] may change, as the case may be.
In any case, which of them (1970c and 1970b) is more appropriate to use, by referring to the Kuhn's Reflections on my Critics?
