Why this is in the register
Hans Quecke, 'Untersuchungen zum Koptischen Stundengebet', Publications de l'Institut orientaliste de Louvain 3 (1970), German with Coptic texts (https://hollis.harvard.edu/permalink/f/1s5nto6/alma990017427470203941). The Bohairic hours are translated into English (R. M. Woolley, 'Coptic Offices', SPCK 1930: https://hollis.harvard.edu/permalink/f/1s5nto6/alma990025740750203941; De Lacy O'Leary, 'The Daily Office and Theotokia of the Coptic Church', 1911: https://archive.org/details/dailyofficetheot0000revd), but no English rendering of the Sahidic office texts edited by Quecke was located in HOLLIS Primo ('Coptic offices', 'Coptic psalmodia', 'Sahidic office'). The Coptic Encyclopedia treats the hours under the Bohairic 'Canonical Hours, Book of' (https://ccdl.claremont.edu/digital/collection/cce/id/413) and a search of its entries for Sahidic office material returned no dedicated article.
Quecke's volume is the standard study and edition of the Sahidic cathedral-office material, which survives only in fragments. The claim is confined to that Sahidic material; the Bohairic Agpeya has multiple English editions (not surveyed here).
No open electronic text was verified for this work. The Greek/Coptic/Geʿez may exist only in a print or subscription edition (Migne, CSCO, TLG, CMCL).
Scanned witnesses
Scan search: restricted scan — 1 candidate(s). The standard edition of the Sahidic office material exists as a restricted lending scan only. Its base manuscript, Pierpont Morgan Library M574, could not be verified as digitised: both https://www.themorgan.org/iiif/M574/manifest.json and corsair.themorgan.org return HTTP 403 behind a Cloudflare 'Just a moment...' interstitial, so no IIIF manifest or shelfmark page could be confirmed - the M574 shelfmark here comes from the IA metadata description of Quecke, not from the Morgan. No other digitised copy of the Quecke volume was located (BnF SRU 'Stundengebet' / 'office copte' returns nothing relevant).
