What’s in a name: associated costs or authority work for artists’ names
Authority control is both the most expensive and important quality of any library catalog. Controlling headings for artists’ names can be more expensive than other personal names, as more time is required for the necessary research needed to determine the preferred form of name and variants. However, the cost associated with controlling artists’ names can be managed through effective use of reference materials and time. How artist headings are used also suggests that, over time, the initial investment can save a library from expenses associated with future catalog maintenance.
Name Authority Work for OCLC Copy Cataloging: Is It Worth the Effort?
ABSTRACT In 1996, a study was undertaken at the University of Arkansas Libraries to evaluate the practice of front-end authority work for monographs copy cataloging. A sample of 283 name headings originating from Library of Congress, OCLC “Enhance” member, and general member copy was examined, and analysis revealed that 47.3 percent of headings correctly matched authority records already present in the library's local file. Another 41.3 percent exactly matched records in the OCLC authority file. These findings prompted the library to cease checking name headings at the point of cataloging. However, the level of inaccuracies present, combined with the value of authority records for cross-reference and note information, ensured that the Database Maintenance Unit would continue to review local headings reports and perform needed authority work.
Multi-layer inpainting on Chinese artwork
Digital inpainting uses spatial or frequency information to restore partially damaged/removed photos and artworks. Most restoration algorithms take a picture as a single layer. We propose a new approach, which subdivides a Chinese painting into several layers. Each layer is inpainted separately. The layer fusion mechanism then finds the optimal inpaint among layers, which are restored layer-bylayer. We apply the algorithm on Chinese and western drawing. The result shows a high PSNR value as well as a high user satisfaction. The demonstration of our work is available at: http://www.mine.tku.edu.tw/demos/inpaint.
