Analysis of information sources in references of the Wikipedia article "Gibbs paradox" in English language version.
In particular, Gibbs failed to point out that an 'integration constant' was not an arbitrary constant, but an arbitrary function. But this has, as we shall see, nontrivial physical consequences. What is remarkable is not that Gibbs should have failed to stress a fine mathematical point in almost the last words he wrote; but that for 80 years thereafter all textbook writers (except possibly Pauli) failed to see it.
