Oxford, Bodleian Library, Bodley 708 (2609): Gregory, "Cura Pastoralis"

365. Oxford, Bodleian Library, Bodley 708 (2609) Gregory, "Cura Pastoralis" [Ker 316; Gneuss 590] HISTORY: A complete copy of Gregory's Latin "Pastoral Care:' representative of an insular textual family of the early uncorrected recension of the "Pastoral Care" (Clement 1985: 1-13; Dekkers in Rommel et al. 1992: 1.106). Written in an anglo-caroline minuscule of ca. 1000, probably at Christ Church, Canterbury. Bishop identified three scribes, one of whose work is extant in several other manuscripts from Christ Church, representing some of the earliest English caroline minuscule at that foundation (Bishop 1971: no. 10, p. xxv and 1959-63: 94 and 420-22). The manuscript likely was acquired by Leofric for Exeter from Christ Church; it appears he acquired other manuscripts from Canterbury, at least one from Christ Church (Oxford, Bodl. Lib., Auct. F.1.15 (343]) (Bishop 1959-63: 415; Drage 1978: 271 and 406; Treharne 2009: 524). Leofric donated the book to Exeter at some point between 1050 and 1072, and, Drage suggests, later rather than earlier in this period (Drage 1978: 37); Leofric's donation inscription was added by one of the scribes of the Exeter scriptorium in the third quarter of the 11c (Drage 1978: 405-6); Bodley 708 has been identified with one of the items donated and listed in Leofric's "Inventory "": the "liber pastoralis" (inventory ed. Lapidge 1994: 137; ed. Conner 1993: 232-33). The manuscript appears to have remained at Exeter through the later Middle Ages, as it is listed in the inventories of 1327 and 1506 (Oliver 1861: 302 and 367). The manuscript was among those donated in 1602 by the Dean and Chapter of Exeter to the Bodleian Library and subsequently rebound

Critical variables of solder paste stencil printing for micro-BGA and fine-pitch QFP

Stencil printing continues to be the dominant method of solder deposition in high-volume surface-mount assembly. Control of the amount of solder paste deposited is critical in the case of fine-pitch and ultrafine-pitch surface-mount assembly. The process is still not well understood as indicated by the fact that industry reports 52-71% surface-mount technology (SMT) defects are related to the solder paste stencil printing process. The purpose of this paper is to identify the critical variables that influence the volume, area, and height of solder paste deposited. An experiment was conducted to investigate the effects of relevant process parameters on the amount of solder paste deposited for ball grid arrays (BGAs) and quad flat packages (QFPs) of five different pitches ranging from 0.76 mm (30 mil) to 0.3 mm (12 mil). The effects of aperture size, aperture shape, board finish, stencil thickness, solder type, and print speed were examined. The deposited solder paste was measured by an inline fully automatic laser-based three-dimensional (3-D) triangulation solder paste inspection system. Analysis of variance (ANOVA) shows that aperture size and stencil thickness are the two most critical variables. A linear relationship between transfer ratio (defined as the ratio of the deposited paste volume to the stencil aperture volume) and area ratio (defined as the ratio of the area of the aperture opening to the area of the aperture wall) is proposed. The analysis indicates that the selection of a proper stencil thickness is the key to controlling the amount of solder paste deposited, and that the selection of maximum stencil thickness should be based on the area ratio. The experimental results are shown to be consistent with a theoretical model, which are also described

Oxford, Bodleian Library, Bodley 311 (2122): Latin Penitentials

356. Oxford, Bodleian Library, Bodley 311 (2122) Latin Penitentials [Ker 307, Gneuss 565] HISTORY: A collection of penitential texts stemming from Irish, A-S, and Frankish traditions, assembled and ordered as a single anthology (Frantzen 1983: 37). The script in the manuscript is a form of caroline minuscule that may be English or continental. The manuscript's origins may have been in north or northwest Francia from the second half of the 10c; however, T.A.M. Bishop found the same hand in four other manuscripts, some with early English provenances and perhaps origins; Bishop finds the main scribe of Bodley 311 in the primary texts of Worcester Cathedral Library Q.8 ff. 165-72 +Add. MS 7 ff. 1-6, El Escorial, E.II.l [129a], Rouen Bibliotheque Municipale U. 107 (1385) ff. 20-26 [444], and in the Latin and OE glosses on CCCC 285 (46] (Bishop 1971: xxv, 18). Dumville (1993: 53- 56) accepts this identification of scribe across these manuscripts, though he does not find the evidence for the glossing in CCCC 285 convincing, thus making the case for an English scribe less secure. The scribe of Bodley 311-who names himself 'John' in the colophon ('IOHANNES ME SCRIPSIT' on f. 85r)-may have worked in a Frankish scriptorium whose books were imported into England in the late 10c or early llc. Frantzen (1983: 37) suggests that Bodley 311 could have been designed for export to England. The book may have come to Worcester, where its fellow, Worcester Cathedral Library Q.8, was located in the 12c (Gameson 1996: 242), though Conner suggests that Bodley 311 was in Exeter in the 10c (1993: 20, but cf. Gameson 1996: 152). A partly erased OE inscription on f. lr in a late 1 0c or early l lc Anglo-Saxon square minuscule links the manuscript to a house dedicated to St Mary. A single OE gloss was added in the early l lc (f. lr, 'eorðe' for 'terra'). Though there is no evidence that the book was in Exeter earlier and it cannot be found in Leofric's donations or inventory, Bodley 311 was in Exeter before the second quarter of the 14c, as the Exeter library inventories of 1327 and 1506 have entries identifiable with Bodley 311 (Oliver 1861: 304 and 368; Ker, Cat.; Conner 1993: 8). The manuscript was refurbished in 1411-12 and chain anchorages, likely from the medieval Exeter library, are now covered by the early 17c recovering (Clarkson 1996: 169-74). The book was part of the foundation gift of 81 manuscripts given to the Bodleian Library by the Dean and Chapter of Exeter in 1602; Thomas Bodley's brother Lawrence was a canon of Exeter and may have induced this gift (Philip 1983: 18). An early modern clip staple in the upper board indicates the book was chained in the Bodleian in the 17c. The book was rebacked in 1956 (Clarkson 1996: 169-74). &nbsp

Promoting Access to Historic Book Structures: A Case Study of the Lord Collection

This project is focused on improving access to the John C. Lord Collection by creating an accessible and adaptable digital catalogue to facilitate use. The 23 volumes in the collection span four centuries and include many different binding structures. Several of the volumes are in bindings contemporary with the text. In 2015 the collection was placed on long-term deposit at the Buffalo State Art Conservation Department from the Buffalo History Museum. The collection has served as a study collection for book conservation students and as a result, the department has generated a large collection of electronic documentation of the collection. Data relating to the collection is stored on the department server but is not easily searchable. If unaddressed, deficiencies in the current system can lead to dissociation of collection records from the items. This project gathered all previously collected data, reports, and studies relating to the collection and created an adaptable finding aid and workflow to facilitate use of the collection
