隨著網際網路的普及，圖書館員亦發現自身不管願意與否皆需投入這個混沌之網路環境中，同時，在加強網路資訊資源的側值上，圖書館員本身應扮演更為主動的角色。然而網路資源中經過審查的資料僅佔極少數，多數資源的新穎性，權威性與廣博性等方面皆令人質疑，可信的網路資源品質評估機制又很缺乏，學術圖書館因此面臨資源選擇與評鑑方面的挑戰。有利用文獻分析法對於網路資源特質、網路資源取得方式、網路資源選擇與評鑑相關問題、圖書館員與網路資源的選擇與評鑑、書目利用指導課程的因應等課題進行探討，以期提出相關討論與建議。

Libraries are finding themselves increasingly drawing into the chaotic Internet environment. The majority of information obtained from the Internet lacks currency, authority, and comprehensiveness. Only a handful of resources are refereed in any way. Unfortunately, there are few trusted mechanisms for assessing the quality of the Internet’s information resources. Academic librarians face many challenges in the Internet environment. This paper tries to discuss the characteristics of Internet resources; the access of Internet resources; problems with selecting and evaluating Internet resources; and the implications for bibliographic instruction librarians in academic libraries.
