随着计算机技术的飞速发展,信息的传播方式正在发生巨大的改变。多媒体、网络、光纤传输、信息高速公路等已是目前信息传播当中很重要的一部分。这对图书馆如何利用这些现代信息技术来开展服务工作来说,既是挑战,又是机遇。一、建立图书馆电子阅览室的必要性。首先,飞速发展的信息产业使信息产品的载体发生了变化,产生了电子出版物。电子出版物的特点是体积小、容量大,普通软盘、光盘只有碗口大小,薄如纸片,但其存储的信息量却十分惊人。一张直径3.5吋的高密软盘可以存储汉字70万个,一张光盘可存储汉字3亿个。一个藏书30万册的中型图书馆,如果平均每册书30万字,约需占地600m~2左右,而利用光盘存储这些资料,只需约300张即可。电子出版物图、文、声、像并茂,读者可以通过多种感
With the rapid development of computer technology, the way of information transmission is undergoing tremendous changes. Multimedia, Internet, optical fiber transmission, information superhighway and so on are the most important part of the current information dissemination. This is both a challenge and an opportunity for libraries to use these modern information technologies to carry out their service work. First, the need to establish a library electronic reading room. First of all, the rapidly developing information industry has changed the carrier of information products and created electronic publications. Electronic publications are characterized by small size, large capacity, ordinary floppy disk, CD-ROM only the size of the mouth, thin as paper, but the amount of stored information is very alarming. A 3.5-inch diameter high-density floppy disk can store 700000 characters, a CD-ROM can store 300000000 characters. A medium-sized library with a collection of 300,000 books will require an area of about 600m2 if the average number of books per book is 300,000 words, and only about 300 copies can be stored using the CD-ROM. Electronic publications figure, text, sound, like and Mao, readers can feel through a variety of
