A description of the catalog division project at the College of Physicians of Philadelphia Library.

This paper describes the procedures used at the Library of the College of Physicians of Philadelphia to divide its ninety-year-old dictionary card catalog. The division was necessitated by overcrowding, obsolete subject headings, and lack of a complete authority list which resulted in like materials being scattered throughout the catalog under several headings. Two catalogs were created: the historical-biographical catalog, representing all works published before 1950 and all works of historical or biographical nature; and the current catalog, containing all works published from 1950 on, excepting historical or biographical materials. The 1950- catalog was further divided into name and subject catalogs, and the subject section was revised according to MeSH. The project was completed in about two years. As a result, searching time has been much reduced, and the library is able to take advantage of the annual revisions of MeSH to update the subject catalog.

收视率导向批判--本质的追问

收视率导向并非如一些人所认为的是民主的化身,那么,收视率导向的本质是什么呢?其实,就其最本质的意义而言,收视率是一种电视节目制作者用以向广告主介绍观众情况以便投放广告的商品,揭示了电视工业最本质的运作机制,是电视节目商品化最明显的表征.收视率导向背后所隐藏的是电视节目乃至这个文化的商品化.     

收视率导向批判——民主的视角

收视率导向之所以值得批判的原因在于:收视率导向将收视率强调到了对节目的去留具有决定性影响的地步,使收视率从测量节目的手段变成了节目存在的目的。商业逻辑置入文化领域,收视率掌控传媒文化,在这个过程中,文化同商品等同,公民同消费者混一,消费能力代替文化品位,受众的文化选择遭到了极大的限制。与其说收视率是规范的民主,倒不如说是金钱的暴政或群氓的狂欢。
