浅谈地方文献的收集,整理和利用 总被引：4，自引：0，他引：4
地方文献的收集、整理和利用是公共图书馆一项非常重要的工作,然而多年来在一些图书馆内部没有得到足够的重视,只重视了传统的购书、借书,冷落了地方文献的工作,致使许多珍贵的地方文献流失、埋没,遭到了不应有的损失。今天,人们在讨论着建设有中国特色社会主义大课题的同时, 相似文献

This article investigates the e-print depositing behavior of physicists and astronomers. Fifty-six PhD students and staff at the Department of Physics and Astronomy at the University College London were interviewed. A survey was also carried out (47.1% response rate). The study investigates the relation between variables such as research area, type of research (theoretical, experimental and so on), and the amount of reading on the patterns of e-print depositing. The findings showed that clear intradisciplinary differences exist among different subfields of physics and astronomy. 相似文献

Salt crystallization is recognized as a major cause of damage to porous building materials, threatening the sustainable preservation of our valuable built heritage. Unfortunately, the crystallization behavior of the detected salt mixtures is complex and not fully understood. While the deliquescence points of single salts are well documented, this is not the case for salts in a mixture where one is confronted with the presence of different cations and anions. In this paper the salt content of the murals and the limestone tracery of the main entrance porch from the sixteenth century church of St. James in Liège, Belgium is investigated and related to the climatic conditions of its environment. Concerning the salt load, the research consists of hygroscopic moisture content measurements, quantitative ion analyses, and the prediction of phase equilibria using the thermodynamic model ECOS/RUNSALT. This model can predict the salt crystallization sequences of a particular ion mixture. The output is mathematically evaluated with collected temperature and relative humidity data, which enables the calculation of the number of salt crystallization–deliquescence cycles. The results show that even small amounts of salts can cause damage over a long period of time when the environment causes frequent cycles of crystallization–deliquescence over time. It is shown how a mixture of small amounts of (double) salts, including hygroscopic ones, can have a significant effect on the decay of historic building materials in the case of daily changing climatic conditions and periods of extreme drought. As a result, the crystallization of double salts and hygroscopic salts such as calcium nitrate cannot be ignored. The scientific method and the results are described. 相似文献

ABSTRACT This memoir is my personal story about how I created and came to curate on the International Counterculture Archive collection, which is held in the Global Resources Center of the George Washington University’s (GWU) Gelman library. The first person narrative relates my first encounters with Soviet rock culture and describes how I turned my initial interest into a Ph.D. dissertation on the subculture of Soviet hippies and traditions of Soviet rock music, which subsequently led to my later work as a librarian and curator. I tell the story of my initial encounters with the members of Soviet/Russian rock music subculture and other countercultural personalities and activists during my first trip to Moscow in 1993 to collect samples of Soviet rock music recordings and rock music zines for the European Division of the Library of Congress. During this formative trip I met with a number of counterculture producers and collectors who were instrumental in helping me build the International Counterculture Archive. Upon leaving the Library of Congress, I continued collecting Soviet/Russian countercultural materials on behalf of the Global Resources Center of GWU’s Gelman Library. I talk about the process of creating the Archive at Gelman library, about bureaucratic and financial aspects of this work, and about my many acquisition trips to Moscow, former Soviet republics, and East Central Europe. Much of the narrative centers on my work with Russian collectors and content producers and describes the type of materials that are included in the collection. I also describe how I built the collection of historical Soviet/Russian rock music recordings, focusing on the phenomenon of Soviet/Russian rock music zines and the history of the unique zine collection within the International Counterculture Archive. 相似文献

圣旨是研究当时社会政治、经济和文化等的珍贵资料。圣旨中的字迹在长期的储存过程中褪色淡化,导致历史信息消失而失去相应的价值。对圣旨褪色的成因进行分析,进而采用显现剂纳米二氧化硅/正丁醇分散液对字迹进行显现。采用红外光谱、扫描电镜和视频接触角考察显现剂对模拟样的影响;通过色差和力学性能评价显现剂对模拟样耐老化性能的影响。结果表明,显现剂能清晰地显现模糊不清的字迹而未明显改变圣旨的形貌和组成结构;提高了圣旨基材的力学性能和耐老化性能,对圣旨的长久保存具有重要意义。该方法对同类型的字迹显现具有一定的借鉴作用。 相似文献
