Our task is to edit the letters of Philipp Jakob Spener and to present them with academic commentary. We have made numerous editorial decisions, and have compiled regulations as a recommended strategy. On this basis, some texts were accepted, and others excluded from the Edition. The accepted letters are presented in a fixed form and the means of transmission and its provenance are described.
Some texts are reproduced from a manuscript, others from a print. Orthography and Punctuation follow standard recommendations for an edition of Early Modern texts.
A Text-Critical Apparatus describes the variants in the origin of the letters and shows the variants arising in their transmission.
A commentary explains the persons, places and factual contexts.
