Many papers in France and England report that the French Government issued a "Yellow Book" (livre jaune) which claimed to prove that the Kaiser was bent on war with their country a year before.
The publication of official diplomatic documents was an innovation that had never been done before. Each government printed selected documents that were meant to throw blame on the other side for the events leading up to the war. On this side of the Atlantic, the publication of the rival documents merely heightened the common belief that secret diplomacy, as conducted by all sides, was at the root of the problem, and led to calls for "open covenants openly arrived at." That would later form the basis for the first of Wilson's Fourteen Points.
After the war, the governments of the belligerent powers raced to open their diplomatic archives in an attempt to bolster their respective positions on the "war guilt question" (
Kriegschuldfrage). Germany, with the most at stake, published the greatest volume of material (stretching back to 1871), but the UK, France, Italy, and Austria all published their own collections of diplomatic documents. The motivation, however, came mostly from Russia, where the Bolsheviks, even before the war ended, had ransacked the archives of the Tsarist foreign ministry and had published secret diplomatic documents that exposed many of the secret deals among the Entente powers. The result was a boon for historians, but the question of who was responsible for starting the war remained unresolved.
