Some notes on WFP's correspondence: 1.) Organization of data entry -- Letters are organized by last name of recipient, alphabetically, and within that from earliest to latest. Items not dated are listed as "no date" and included at the end of each person's correspondence. Circular letters are entered by name of first person on list. 2.) Source material -- includes handwritten and typed letters, as originals and/or copies, either in looseleaf form or as letter press book entries. The WFP correspondence collection contains four press books, identified as A (Oct. 1890-Feb. 1899); B (Feb. 1899-April 1904); C (April 1904-July 1908); and D (July 1908-Sept. 1909). Foldered correspondence is in WF Pendleton Correspondence Boxes 1-5 alphabetically; press books are in two boxes labeled Box 6, one letter size box and one legal size. Letter Press Books A and B were transcribed in the 1980s; significant ink degradation has occured between then and the 2016-19 data entry dates. (Some letters that were legible then, no longer are.) Because of this rapid degradation, Press Books C and D, along with being heavily quoted in order to preserve their primary source material, are being digitally captured in 2019 to preserve them. Letters from WFP's many secretaries are included as letters from him. 3.) Annotations -- In addition to annotations made by WFP, his letters contain annotations in many other hands: those of his various secretaries; those of Katherine Benade; those of E. Bruce Glenn and possibly Joyce Bellinger, confirming Press Book A and B transcription dates as the 1980s while EBG was Glencairn director and head of the archives. It is difficult to determine which annotations are reliable and which are unsubstantiated, therefore only those annotations clearly in WFP's hand were included in the data entry. 4.) Variant spellings -- WFP used variant spellings of names of church groups, people, and locations. For consistency, data entry reflects the use of one spelling for names, with occasional reminders in parentheses that when searching these entries, a full search should include possible variant spellings. For church groups: Berlin (Carmel Church); Chicago (Sharon Church, sometimes referred to as separate groups -- East, West, and South Side groups); Toronto (Parkland Church); and Glenview (Immanuel Church). For name variants: Czerny(ey); Cram (Kram); deCharms, deChazal (de Charms, de Chazal); Fuller (Tuller); Gunthers (Guenthers); Kramph (Krampf, Kramff); Pittsburg(h); JP Stuart ("The General,"; Stewart). Searching under names as WFP would have used them is recommended, as his correspondence often includes only a first or last name (e.g. "Miss Alice" for Alice Grant, or "Mr. Pitcairn" for John Pitcairn). Some letters refer to "The Captain" (unknown) or "the Chancellor" (WH Benade). 5.) General Church organizations -- the term "General Church" is used by WFP to refer to one of at least three organizations containing that as part of its name: in 1883, Benade reorganized the Pennsylvania Association as "The General Church of Pennsylvania"; in 1890, the General Church of Pennsylvania seceded from Convention and called itself "The General Church of the Advent"; in 1897, WFP and many others broke with Benade, resigned from "The General Church of the Advent," and moved from Philadelphia to Bryn Athyn, forming "The General Church of the New Jerusalem," at which time WFP was asked to be the leader of this new organization. Searching by timeline (years) will help clarify important organizational shifts, as organizational name changes occur after separations occur. 6.) Subject searches -- As much as possible, WFP's terminology for certain subjects was retained. For the sake of clarity in modern-day research, however, the "about" list ("re") for each letter uses modern terminology. For example, a letter might use "Negro" or "colored man" for "black" or "African-American"; "prevention of offspring" for "birth control," etc. 7.) Of special note: Some of WFP's letters contain anecdotal accounts of his Civil War experiences, including mention of his "not infrequent" encounters with General Robert E. Lee. These were hopefully all flagged as "Civil War" in the "re" data entry line. In addition, some original New Church music, including unpublished handwritten lyrics and scores, is contained in some of his letters. These were data entered under "music," "Liturgy/new Liturgy," or "Hymnal/new Hymnal." (More umpublished original music is in his collection of papers, but those in his letters may not be included there.)
