Title: On the Quantum Theory of Line-Spectra.
Description: København, Hovedkommissionaer: Andr. Fred. Høst & Søn, Kgl. Hof-Boghandel, Bianco Lunos Bogtrykkeri, 1918. , 1918, 1922. In 3 parts. Original printed wrappers. (Part 1 some discolouring). (36; (37-) - 100; (101-) - 118 pp.). (Offprints). (From: "Mémoires de l'Académie Royale des Sciences et des Lettres de Danemark, Copenhague, Section des Sciences, 8me série, t. IV, fasc. 1 [2, 3]"). Trade edition, the lower wrappers of the first 2 parts w. [identical] adverts up to 1920, the third part, w. added adverts for the 3rd Bohr part 1922, added adverts for class V, nr 3 [Brünnich Nielsen], Class VI, 2 [Lundblad] and Class VII, 1 [Wesenberg-Lund]. DSB II, pp. 239 - 254: 'By 1918 Bohr had visualized, at least in outline, the whole theory of atomic phenomena, ...He of course realized that he was still very far from a logically consistent framework wide enough to incorporate both the quantum postulates and those aspects of classical mechanics and electrodynamics that seemed to retain some validity. Nevertheless, he at once started writing up a synthetic exposition of his arguments and of all the evidence upon which they could have any bearing; in testing how well he could summarize what was known, he found occasion to check the soundness of his ideas and to improve their formulation. In the present case, however, he could hardly keep pace with the growth of the subject; the paper he had in mind at the beginning developed into a four-part treatise, "On the Theory of Line Spectra", publication of which dragged over four years without being completed; the first three parts appeared between 1918 and 1922, and the fourth, unfortunately, was never published. Thus the full impact of Bohr's view remained confined to the small but brilliant circle of his disciples, who indeed managed better than their master to make them more widely known by the prompter publication of their own results.
