This source edi­tion does not rep­re­sent a com­plete set of archival hold­ings, but is com­posed of doc­u­ments se­lected from dif­fer­ent archives and in­sti­tu­tions based on their con­tent. Longer texts or ex­pan­sive image files/au­dio­vi­sual doc­u­ments are ex­cerpted to present key pas­sages or parts of this source. Where the rights could be ob­tained, both the ex­cerpted ver­sion (an­no­tated ac­cord­ing to our edi­tion guide­lines) and the en­tire source are in­cluded; if a dig­i­tized ver­sion of a source al­ready ex­ists, a link is in­cluded. The main cri­te­rion for source se­lec­tion is the idea of “key doc­u­ments.”

    The term key doc­u­ments de­scribes se­lected sources which are used as ex­am­ples to pro­vide in­sight into his­tor­i­cal con­texts and events. Key doc­u­ments are sup­posed to “open doors” lead­ing to a bet­ter and more vivid un­der­stand­ing of his­tory. Whether these are well-​known records – such as by-​laws and other legal doc­u­ments – or pre­vi­ously lit­tle stud­ied sources, ef­forts were con­sis­tently made to en­sure the rep­re­sen­ta­tive char­ac­ter of the en­tire vol­ume of doc­u­ments. The se­lec­tion of the in­ter­preted and edited sources is a re­sult of close co­op­er­a­tion be­tween the ed­i­to­r­ial staff, the au­thors, and ed­i­tors.

    The fol­low­ing cri­te­ria were cen­tral to the se­lec­tion of sources which in­clude texts, im­ages, sound record­ings, and au­dio­vi­sual files.

    connect to a broader historical context / pose questions represent an example from a larger volume of sources or tell a “typical” story because of its uniqueness be clearly identifiable based on extensive information on the source (time of creation, author, etc.)

    The basic idea is that each source and its com­men­tary should be closely con­nected in order to allow ref­er­ences back to the source and in­fer­ences from it in a man­ner that is as trans­par­ent as pos­si­ble. The reader is en­cour­aged to not just fol­low the in­ter­pre­ta­tion, but at­tempt their own in­ter­pre­ta­tion. In order to en­sure this, fo­cus­ing on short doc­u­ments seemed nec­es­sary.
