RDA implementation and application: British Library

The British Library implemented the new international cataloguing standard RDA in April 2013. The paper describes the reasons for the change, the project organization, the necessary adaptations to the systems and the training programs. Altogether, 227 staff were trained. Productivity levels by now are comparable with the levels for AACR2. However, there was a tendency to spend too much time on authority control.Die British Library hat den neuen internationalen Katalogisierungsstandard RDA im April 2013 eingeführt. Der Beitrag beschreibt die Gründe für den Umstieg, die Projektorganisation, die notwendigen Anpassungen bei den Systemen und die Schulungsmaßnahmen. Insgesamt 227 Mitarbeiter/innen wurden geschult. Mittlerweile wird eine vergleichbare Produktivität erreicht wie unter AACR2. Jedoch bestand eine Tendenz, zu viel Aufwand in die Normdatenarbeit zu stecken

In quiet times, the riometer voltage series is accurately modeled by a stochastic process whose components include both a six term expansion in harmonic functions and some amplitude modulated modes of lower signal to noise ratio (SNR). In units of cycles per sidereal day (cpsd), the frequencies of the six harmonic functions lie within 0.01 cpsd of an integer. Earth's rotation induces a splitting of the low SNR components, resulting in the appearance of nine multiplets in standardized power spectrum estimates of the considered CRA voltage series. A second feature of these spectrum estimates is a 6 min periodic element appearing in both the CRA voltage series and the proton mass density series of the Advanced Composition Explorer (ACE). Spectral peak frequencies have been detected, which lie near established solar mode frequency estimates. In addition, some of these peak frequency estimates are coincident with peak frequency estimates of the standardized power spectra for the time series of proton mass density and interplanetary magnetic field strength (IMF) at ACE.“Marshall_Francois_Supporting_Information_JGR_2019.pdf” contains a summary of the supporting information. The 1 hr sampled F10.7 series was obtained from DRAO (National Research Council, 2017). The three MAG time series of IMF strength were acquired from The ACE Science Center (2007), while the SWEPAM time series of proton mass density was acquired from Space Weather Prediction Center, National Oceanic and Atmospheric Administration (2018). The relevant data sets for the analysis of this paper are included in Marshall (2019). This work was supported by the Natural Sciences and Engineering Research Council of Canada (NSERC), Canadian Statistical Sciences Institute (CANSSI), Bonneyville Power Authority, and Queen's University. David J. Thomson, the official holder of the grants and contracts, provided research and conference funding to advance this project. Special thanks to Ken F. Tapping (DRAO of NRCan) for his guidance in finding the data sets relevant to solar radio emissions. Glen Takahara, of the Department of Mathematics and Statistics at Queen's University, suggested exploring different data sets to confirm the modal origin of spectral peaks observed in the Ottawa riometer of the CRA. Alessandra A. Pacini of the Arecibo Observatory recommended checking to see if some of the modes could have been driven by the harmonics of Earth's rotation. Frank Vernon of the Institute of Geophysics and Planetary Physics at Scripps Institution of Oceanography confirmed how seismic data could be expected to reveal coincident spectral peaks at the detected frequencies in the riometer standardized spectra.2020-10-2

The Anglo-American Authority File: A PCC Story

This article examines the motivations for the collaboration between the British Library and Library of Congress to develop a joint (Anglo-American) authority file. It describes the obstacles that had to be overcome for the British Library to become a Name Authority Cooperative (NACO) “copy holder”, or node. It considers the contribution the British Library made to NACO, the benefits it has derived from participation in Program for Cooperative Cataloging (PCC), and concludes by looking ahead to the next 25 years

Linked and open data: RDA and bibliographic control

RDA: Resource Description and Access, is a new cataloguing standard which will replace the Anglo-American Cataloguing Rules, 2nd edition, which has been widely used in libraries since 1981. RDA, like AACR2, is a content standard providing guidance and instruction on how to identify and record attributes or properties of resources which are significant for discovery. RDA is also an implementation of the FRBR and FRAD models. The RDA element set and vocabularies are being published on the Open Metadata Registry as linked open data. RDA provides a rich vocabulary for the description of resources and for expressing relationships between them. This paper describes what RDA offers and considers the challenges and potential of linked open data in the broader framework of bibliographic control
