The literature of the Macedonian question is enormous. Among pre-War works on the subject by impartial outsiders, one would name especially: Victor Bérard, _La Turquie et l’hellénisme contemporain_, Paris, 1896, and _La Macédoine_, Paris, 1897; H. N. Brailsford, _Macedonia, its Races and their Future_, London, 1906; and G. Amadori-Virgilj, _La Questione rumeliota_, vol. i, Bitonto, 1908 (also very useful on Albania and Epirus). The Bulgarian claims to Macedonia are set forth notably by “A. Ofeikov” (pseudonym for Šopov), _La Macédoine au point de vue ethnographique, historique et philologique_, Philippopolis, 1887; S. Radeff, _La Macédoine et la renaissance bulgare au XIXᵉ siècle_, Sofia, 1918; and V. Sís, _Mazedonien, eine Studie über Geographie, Geschichte, Volkskunde ..._, Zurich, 1918. The Serbian point of view is presented by T. R. Georgevitch, _Macedonia_, London, 1918; Jovan Cvijić, _Questions balkaniques_, Paris, 1916; and A. Belić, _La Macédoine, études ethnographiques et politiques_, Paris, 1919. For the Greek side of the case, see M. Paillares, _L’Imbroglio macédonien_, Paris, 1907; and S. P. Phocas-Cosmetatos, _La Macédoine, son passé et son présent_, Paris, 1919. Regarding the Dobrudja question, the Roumanian claims are set forth by N. P. Comnène, _La Dobrogea: essai historique, économique, ethnographique, et politique_, Paris, 1918; and the Bulgarian standpoint is upheld by A. Ishirkov, _Les Bulgares en Dobrudja; aperçu historique et ethnographique_, Berne, 1919. On the question of Northern Epirus (or Southern Albania) one may consult, for the Greek side, N. J. Cassavetes, _The Question of Northern Epirus at the Peace Conference_, Boston, 1919; and R. Puaux, _The Sorrows of Epirus_, London, 1918. The Albanian point of view in this and other questions is set forth by C. A. Chekrezi, _Albania Past and Present_, New York, 1919; C. A. Dako, _Albania, the Master Key to the Near East_, Boston, 1919; and in the _Memorandum submitted by the Albanian Delegation to the Peace Conference_ (published by the Association for International Conciliation, American Branch, New York, 1919: no. 138 of their series). Very little has yet been published on the question of Thrace. The most useful compendium of maps, statistics, and historical and ethnographic data about it is _The Question of Thrace: Greeks, Bulgars, and Turks_, by J. Saxon Mills and M. G. Chrussachi, London, 1919 (primarily based on Bulgarian data, used to refute Bulgarian claims). On the problem of the Straits, the best treatment--both historical and analytical--is probably to be found in the recent volume by Coleman Philippson and Noel Buxton, _The Question of the Bosphorus and the Dardanelles_, London, 1917. A brief but excellent essay is A. C. Coolidge’s _Claimants to Constantinople_, Cambridge, Mass., 1917.
