  • WHAT IS a SERIAL? (AACR2R Chapter 12/LCRI 12.0A)
    WHAT IS A SERIAL? (AACR2R Chapter 12/LCRI 12.0A) Publication should meet all three criteria 1) Publication is issued in successive parts periodicals annual reports and recurring reports directories, yearbooks newsletters statistical publications newspapers, etc. 2) Publication bears a numeric and/or chronological designation Numeric or chronological designation is a number or date given in a prominent position on the publication that distinguishes each individual issue Designation is used to identify each issue for check-in, organization, and retrieval 3) Publication is intended to continue indefinitely This is often the most difficult of the criteria to determine Publications not usually treated as serials Encyclopedias Dictionaries Censuses Multi-volume sets with finite numbers of parts Publications of a limited duration Publications revised on an irregular or infrequent basis Publications that are fuzzy Loose-leafs Cumulations Travel books Conference publications KEY POINTS OF SERIALS CATALOGING Base description on first or earliest issue. Every serial record should have a 362 or a 500 Description based on note. New record is created each time the title proper or corporate body (if main entry) changes. (See Serial title changes that require a new record) Cataloging record must represent the entire serial. Bib record must be general enough to apply to the entire serial, but specific enough to cover all access points. Notes are used to show changes in place of publication, publisher, issuing body, frequency, etc. Serial records should never have ISBN numbers for separate issues. Every serial should have a unique title. This is often accomplished with uniform titles. (See Uniform titles) Most serials do not have personal authors.

  • The Denarius – in the Middle Ages the Basis for Everyday Money As Well
    The Denarius – in the Middle Ages the Basis for Everyday Money as well In France the coin was known as "denier," in Italy as "denaro," in German speaking regions as "Pfennig," in England as "penny," – but in his essence, it always was the denarius, the traditional silver coin of ancient Rome. In his coinage reform of the 780s AD, Charlemagne had revalued and reintroduced the distinguished denarius as standard coin of the Carolingian Empire. Indeed for the following 700 years, the denarius remained the major European trade coin. Then, in the 13th century, the Carolingian denarius developed into the "grossus denarius," a thick silver coin of six denarii that was later called "gros," "grosso," "groschen" or "groat." The denarius has lasted until this day – for instance in the dime, the North American 10 cent-coin. But see for yourself. 1 von 15 www.sunflower.ch Frankish Empire, Charlemagne (768-814), Denarius (Pfennig), after 794, Milan Denomination: Denarius (Pfennig) Mint Authority: Emperor Charlemagne Mint: Milan Year of Issue: 793 Weight (g): 1.72 Diameter (mm): 20.0 Material: Silver Owner: Sunflower Foundation The pfennig was the successor to the Roman denarius. The German word "pfennig" and the English term "penny" correspond to the Latin term "denarius" – the d on the old English copper pennies derived precisely from this connection. The French coin name "denier" stemmed from the Latin term as well. This pfennig is a coin of Charlemagne, who in 793/794 conducted a comprehensive reform of the Carolingian coinage. Charlemagne's "novi denarii," as they were called in the Synod of Frankfurt in 794, bore the royal monogram that was also used to authenticate official documents.

  • Propositiones Ad Acuendos Iuvenes
    ‘ECCE FABULA!’ PROBLEM-SOLVING BY NUMBERS IN THE CAROLINGIAN WORLD: THE CASE OF THE PROPOSITIONES AD ACUENDOS IUVENES BY RUTGER KRAMER Austrian Academy of Sciences 'Ich habe bemerkt', sagte Herr K., 'daß wir viele abschrecken von unserer Lehre dadurch, daß wir auf alles eine Antwort wissen. Könnten wir nicht im Interesse der Propaganda eine Liste der Fragen aufstellen, die uns ganz ungelöst 1 erscheinen?' Sometime in the mid-780s, Charlemagne, King of the Franks, had a letter composed in his name, and sent it to all of the abbots and bishops in his realm. His goals were as ambitious as they were reflective of a basic need to reinvigorate the pursuit of knowledge among his prelates. To start this endeavour, the letter states, it was vital to make sure that education in the realm was up to par: For although correct conduct may be better than knowledge, 1 Bertolt Brecht, Geschichten vom Herrn Keuner (Frankfurt am Main: Suhrkamp, 1971), ll. 239-43 ['"I have noticed", said Mr. K., "that we put many people off our teaching because we have an answer to everything. Could we not, in the interests of propaganda, draw up a list of questions that appear to us completely unsolved?"', Stories of Mr. Keuner, trans. by Martin Chalmers (San Francisco: City Lights Books, 2001), p. 18]. 16 Rutger Kramer nevertheless knowledge precedes conduct. Therefore, everyone ought to study what he desires to accomplish, so that so much the more fully the mind may know what ought to be done, as the tongue hastens in the praises of omnipotent God without the hindrances of errors.

  • Christian Apostate Literature in Medieval Islam Dissertation
    Voices of the Converted: Christian Apostate Literature in Medieval Islam Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Clint Hackenburg, M.A. Graduate Program in Near Eastern Languages and Cultures The Ohio State University 2015 Dissertation Committee: Kevin van Bladel, Advisor Bilal Orfali Hadi Jorati Copyright by Clint Hackenburg 2015 Abstract This dissertation seeks to discuss the dialectical (kalām) and scriptural (both biblical and qurʾānic) reasoning used to justify Christian conversion to Islam during the medieval period (750 - 1492 C.E.). With this objective in mind, I will compare and contrast the manners in which five different Arabophone authors, ʿAlī ibn Sahl Rabban al-Ṭabarī (d. ca. 860), al-Ḥasan ibn Ayyūb (fl. ca. mid-tenth century), Naṣr ibn Yaḥyā (d. 1163 or 1193), Yūsuf al-Lubnānī (d. ca mid-thirteenth century), and Anselm Turmeda (d. 1423), all Christian converts to Islam, utilized biblical and qurʾānic proof-texts alongside dialectical reasoning to invalidate the various tenets of Christianity while concurrently endorsing Islamic doctrine. These authors discuss a wide variety of contentious issues pervading medieval Christian-Muslim dialogue. Within the doctrinal sphere, these authors primarily discuss the Trinity and Incarnation, the nature of God, and the corruption of the Bible (taḥrīf). Within the exegetical realm, these authors primarily discussed miracles, prophecy, and prophetology. Moreover, this dissertation seeks to discern how these authors and their works can be properly contextualized within the larger framework of medieval Arabic polemical literature. That is to say, aside from parallels and correspondences with one another, what connections, if any, do these authors have with other contemporary Arabophone Muslim, Christian, and, to a lesser extent, Jewish apologists and polemicists? ii In the course of my research on Christian apostate literature, I have come to two primary conclusions.

Bachrach 00 Charlemagne’s Health in ‘Old Age’: Did It Affect Carolingian Military Strategy? 00 11 During the first thirty-three years of his reign as king of the Franks, i.e., prior to his 54 coronation as emperor on Christmas day 800, Charlemagne, scholars generally agree, pursued a successful long-term offensive and expansionist strategy. This strategy was 2020 aimed at conquering large swaths of erstwhile imperial territory in the west and brin- ging under Carolingian rule a wide variety of peoples, who either themselves or their regional predecessors previously had not been subject to Frankish regnum.1 For a very long time, scholars took the position that Charlemagne continued to pursue this expan- sionist strategy throughout the imperial years, i.e., from his coronation on Christmas Day 800 until his final illness in later January 814. For example, Louis Halphen obser- ved: “comme empereur, Charles poursuit, sans plus, l’oeuvre entamée avant l’an 800.”2 F. L. Ganshof, who also wrote several studies treating Charlemagne’s army, was in lock step with Halphen and observed: “As emperor, Charlemagne pursued the political and military course he had been following before 25 December 800.”3 In a similar vein, Ferdinand Lot made clear that Charlemagne continued his previ- ous expansionist war aims and divided the responsibilities for carrying out his impe- rial strategy of expansion among his three sons. Lot observed: “Il laisse ce soin à ses fils: Charles, l’ainé, lutte contre les Slaves; Pépin, roi d’Italie, contra les Avars...; Louis bataille dans la Marche d’Espagne.

  • Appropriations of the Master's Legacy
    Appropriations Of The Master’s Legacy 167 Chapter 5 Appropriations of the Master’s Legacy Just enough evidence survives in the textual record of the eighth, ninth, and tenth centuries to enable us not only to document the transformation of Wang Tong’s legacy over this span of time, but to glimpse its progress in stages. As the previous chapter revealed, the crafting of Master Wenzhong’s image in the sev- enth century was essentially a family project of the Wangs, who hallowed their ancestor for his Confucius-like comportment and convictions and his tireless crusade to restore the classical ideals and teachings of the ancient sage kings. We saw also that by the time of Lu Guimeng’s “Preface to a Letter Sent with Mr. Doulu,” written in the late ninth century and quoted at the chapter’s close, Wang Tong’s name had to some extent entered into general currency and the terms of his praises had expanded. Several late Tang and early Song texts will hereaf- ter complete the available picture, by showing how in certain men’s minds Wang Tong merited veneration, if not official canonization, as a divinely sent Confucian Worthy. Through his putative tutelage of the ablest ministers at Taizong’s court, they also reasoned, Wang Tong was nothing less than the intel- lectual father of the Tang Dynasty. The present chapter traces the process of this transformation and interprets its implications for our understanding of the tex- tual history of the Zhongshuo. The pivotal historical event in this story, as it is of Tang history generally, is the An Lushan rebellion of the mid-eighth century (755–763), after which the empire never recovered its former stability let alone the former reach of its administrative control.

  • Solar Activity Around AD 775 from Aurorae and Radiocarbon
    Astron. Nachr. / AN 999, No.88, 789–812 (2011) / DOI please set DOI! Solar activity around AD 775 from aurorae and radiocarbon R. Neuhauser¨ 1 ⋆ and D.L. Neuhauser¨ 2 1 Astrophysikalisches Institut und Universit¨ats-Sternwarte, FSU Jena, Schillerg¨aßchen 2-3, 07745 Jena, Germany 2 Schillbachstraße 42, 07743 Jena, Germany Received Nov 2014, accepted 27 Feb 2015 Published online Key words AD 775 – solar activity – aurorae – sunspots – radiocarbon – history of astronomy A large variation in 14C around AD 775 has been considered to be caused by one or more solar super-flares within one year. We critically review all known aurora reports from Europe as well as the Near, Middle, and Far East from AD 731 to 825 and find 39 likely true aurorae plus four more potential aurorae and 24 other reports about halos, meteors, thunderstorms etc., which were previously misinterpreted as aurorae or misdated; we assign probabilities for all events according to five aurora criteria. We find very likely true aurorae in AD 743, 745, 762, 765, 772, 773, 793, 796, 807, and 817. There were two aurorae in the early 770s observed near Amida (now Diyarbakır in Turkey near the Turkish-Syrian border), which were not only red, but also green-yellow – being at a relatively low geomagnetic latidude, they indicate a relatively strong solar storm. However, it cannot be argued that those aurorae (geomagnetical latitude 43 to 50◦, considering five different reconstructions of the geomagnetic pole) could be connected to one or more solar super-flares causing the 14C increase around AD 775: There are several reports about low- to mid-latitude aurorae at 32 to 44◦ geomagnetical latitude in China and Iraq; some of them were likely observed (quasi-)simultaneously in two of three areas (Europe, Byzantium/Arabia, East Asia), one lasted several nights, and some indicate a particulary strong geomagnetic storm (red colour and dynamics), namely in AD 745, 762, 793, 807, and 817 – always without 14C peaks.
