【摘要】：信息時代的圖書館不僅僅限于傳統(tǒng)的紙質書刊服務,而是著重發(fā)展數(shù)字圖書館,收集并保存各種數(shù)字信息資源。一方面,圖書館每天都在不斷地增加數(shù)字信息資源的容量;另一方面,其購買的數(shù)字信息資源又受到知識產(chǎn)權的保護和數(shù)字資源提供商的授權限制,只能在圖書館內部使用,無法通過互聯(lián)網(wǎng)進行訪問。這大大限制了數(shù)字信息資源的傳播,提高了用戶對信息資源的訪問時間和能源成本。因此,建立一種有效的數(shù)字信息資源共享模式,讓圖書館的所有使用者都可以免費、便捷地在外網(wǎng)訪問本館數(shù)字信息資源,是本課題所要解決的問題。本課題研究并提出了一種既可以保證圖書館合法用戶在信息資源提供商許可并授權的前提下可以通過互聯(lián)網(wǎng)隨時隨地訪問圖書館購買的數(shù)字信息資源,又不影響圖書館網(wǎng)絡系統(tǒng)安全和內部辦公的解決方案,從而最大化的實現(xiàn)數(shù)字信息資源的共享。本課題設計并實現(xiàn)了成都圖書館信息資源共享系統(tǒng),它是基于遠程訪問服務RAS(Remote Access Service)的數(shù)字信息資源共享系統(tǒng),采用Squid代理技術、ASP.NET、SQL Server 2005數(shù)據(jù)庫等實現(xiàn)圖書館合法用戶通過互聯(lián)網(wǎng)隨時隨地訪問成都圖書館內部的數(shù)字信息資源。同時根據(jù)管理員與用戶的不同,實現(xiàn)系統(tǒng)登錄身份認證、用戶信息管理、用戶公告、用戶留言回復等功能,從而解決了圖書館信息資源共享的問題。本課題的實現(xiàn),極大增加了圖書館數(shù)字信息資源的利用率,適應了信息網(wǎng)絡發(fā)展的大趨勢,使圖書館可以有效給每一個使用其購買的數(shù)字資源的用戶授權,從而也解決了信息資源提供商的利益和版權問題。更深層次的意義在于圖書館授權用戶可以在家中甚至是國外通過互聯(lián)網(wǎng)訪問圖書館的數(shù)字資源,延伸了信息資源的共享范圍,從而在技術上解決了用戶在查找、使用信息實存在的地域、時間、精力等不對稱現(xiàn)象。
[Abstract]:The library in the information age is not only limited to the traditional paper-based books and periodicals, but also focuses on the development of digital libraries and the collection and preservation of all kinds of digital information resources. On the one hand, the library is constantly increasing the capacity of digital information resources every day; On the other hand, the digital information resources it buys are restricted by the protection of intellectual property rights and the authorization of the digital resource providers, which can only be used in the library and cannot be accessed through the Internet. This greatly limits the dissemination of digital information resources and increases the access time and energy cost of users to information resources. Therefore, to establish an effective mode of sharing digital information resources, so that all users of the library can access the digital information resources of the library free of charge and convenient on the external network, is the problem to be solved in this paper. This paper studies and puts forward a kind of digital information resources which can guarantee the library legal users can access the digital information resources purchased by the library at any time, anywhere through the Internet, under the premise of the license and authorization of the information resources provider. It does not affect the security of library network system and the solution of internal office, so as to maximize the sharing of digital information resources. This paper designs and implements the information resource sharing system of Chengdu Library. It is a digital information resource sharing system based on remote access service RAS (Remote Access Service). It adopts Squid agent technology and ASP.NET,. SQL Server 2005 database can access the digital information resources of Chengdu library at any time, anywhere through the Internet. At the same time, according to the difference between the administrator and the user, the system realizes the functions of login authentication, user information management, user announcement, user message reply and so on, thus solving the problem of information resource sharing in the library. The realization of this subject greatly increases the utilization rate of library digital information resources, adapts to the general trend of the development of information network, and enables the library to effectively authorize every user who uses the digital resources purchased by him or her. Thus also solved the information resource provider's interest and the copyright problem. The deeper significance is that the authorized users of the library can access the digital resources of the library at home and even abroad through the Internet, extending the sharing scope of the information resources, and thus technically solving the users' search. The use of information exists in the region, time, energy and other asymmetrical phenomena.
