Unless otherwise indicated, all letters by Greve are manuscript or typescript documents which were obtained for the University of Manitoba Archival FPG (Greve/Grove) Collections over many years from various archives, libraries, special collections, or private hands. Details of their origins, extent, importance and provenance are fully listed in the comprehensive "Sources" section of the Bibliography [under development].

Grove's earliest letters to Isaak J. Warkentin have been included here, because of their German content: Warkentin was a student in Leipzig when FPG wrote to him from Winkler, Manitoba, in 1913/14. Especially the fifth & last letter in this correspondence addresses German conditions & politics, beyond having confessional character.

By far the most common format of Greve's known correspondence are manuscript letters which are left unmarked, while typed letters are marked "TY", postcards are marked "PC", and telegrams are marked "TE."

A few revealing accounts, reports, remarks or observations ABOUT Greve (and also, occasionally, about his companion Else during their relationship from 1902 to 1911) in letters, private journals, diaries, autobiographical notes, newspaper accounts, etc. by Greve's European contemporaries have been integrated in the chronological sequence of his letters. They are marked "MI" for "miscellaneous."

Else von Freytag-Loringhoven's reminiscences, written for Djuna Barnes from Berlin during 1923 and 1926, abound with details about her affair with Greve up to the time he left her near Sparta, Kentucky. Relevant passages are marked "FrL."
