The computation of Euler’s constant, γ, to 3566 decimal places by a procedure not previously used is described. As a part of this computation, the natural logarithm of 2 has been evaluated to 3683 decimal places. A different procedure was used in computations of γ performed by J. C. Adams in 1878  and J. W. Wrench, Jr. in 1952 , and recently by D. E. Knuth . This latter procedure is critically compared with that used in the present calculation. The new approximations to γ and In 2 are reproduced in extenso at the end of this paper.
