The peculiar difficulties of historical work can be understood only by those who have experienced them. General information is the easiest of all things to obtain--exact information the hardest, and a history that is not accurate has no practical utility. If a reader discover one mistake it vitiates the whole book. Every historian knows how common it is to find several totally different statements of the same occurrence, each apparently as authentic as the others. He also knows the eel-like elusiveness of dates and the flat contradictions of statistics which seem to disprove absolutely the adage that "figures do not lie." He has suffered the nightmare of wrestling with proper names; and if he is conscientious he has agonized over the attempt to do exact justice to the actors in the drama which he is depicting and yet not detract from its value by loading it with trivial details, of vital moment to those who were concerned in them but of no importance to future readers. All of these embarrassments are intensified in a history of a movement for many years unnoticed or greatly misrepresented in the public press, and its records usually not considered of sufficient value to be officially preserved. None, however, has required such supreme courage and faithfulness from its adherents and this fact makes all the more obligatory the preserving of their names and deeds. To collect the needful information from fifty States and Territories and arrange it for publication has required the careful and constant work of over two years. It has been necessary many times to appeal to public officials, who have been most obliging, but the main dependence has been on the women of various localities who are connected with the suffrage associations. These women have spent weeks of time and labor, writing letters, visiting libraries, examining records, and often leaving their homes and going to the State capital to search the archives. All this has been done without financial compensation, and it is largely through their assistance that the editors have been able to prepare this volume. To give an idea of the exacting work required it may be stated that to obtain authentic data on one particular point the writer of the Kansas chapter sent 198 letters to 178 city clerks. The meager record of Florida necessitated about thirty letters of inquiry. Several thousand were sent out by the editors of the History, while the number exchanged within the various States is beyond computation.
