 Although this was not much of an increase over the 10th edition (which named 37 female contributors out of 1800 total), it was heralded publicly as a major advance in recognizing the contributions of women in learned circles.However, the 11th edition did employ hundreds of women to write unsigned articles; some women, such as Irish medical expert Harriet Hennessy, even rose to be (uncredited) department editors.Sales figures for the 11th edition were comparable to those of the 9th, which sold hundreds of thousands of copies including the unlicensed sets.
