This paper analyzes the effects of Google Books upon collection development efforts in academic libraries. Other mass digitization projects are also briefly discussed. The focus is on the hurdles that these projects face such as copyright questions, long-term technological planning, and continuing permanent funding. The authors also examine the role of digitization projects as a form of preservation and/or conservation. Finally, the paper looks at the culture of libraries, how use of library materials may change as a result of these projects, gives some ideas of how the public will want to access information, and presents some thoughts about how libraries can maintain their relevance even as the public has access to a wealth of digital resources. 本文分析了Google Books 對學術圖書館館藏發展的影響，並概述了其他大規模數位化的專案。本文重點在於對這些數位化專案所面臨的障礙之探討，如版權問題、長程技術規劃、和持久性資金撥款。作者也探討了這些數位化專案對圖書館館藏保存和保護所扮演的角色。文章最後審視了這些專案將如何改變公眾對圖書館資源的使用和獲取資訊的需求，並提供圖書館在面臨大量開放性豐富數位資源的情況下，如何保持其職能相關性之幾點思考。 頁次：18-30
