This reissuing of The Double Helix, now adorned with umpteen photographs, reprints of first pages of articles, personal letters (some in scrawled—illegible—handwriting), sketches, etc., is not your usual reprint, but I hasten to say that it does make sense. The added material fleshes out the events of that time, with collected accouterments that appeal to both the eye and the mind. Some are purely illustrative (e. g., a photo of the Idlewild Airport observation deck in the late 1940s or a heavy foggy November night in London in the 1950s) and could be considered superfluous, but most are OK, or even better than that.
