文章重點勾稽並梳理了國立西南聯合大學圖書館在長沙和昆明期間的建設歷程，力求對西南聯大圖書館近9年的歷史進行比較全面和系統的整理與回顧。在國難當頭、風雨飄搖、烽火連天的艱苦環境，在經費受限、圖書資料、設備儀器和人員物資極度匱乏的情況下，西南聯大圖書館同仁，篳路藍縷，砥礪前行，守護圖書，傳播知識，堅持圖書館建設、規範圖書館工作流程，想盡一切辦法補充文獻資源，開展各種圖書館業務活動，為西南聯大的教學和科研提供全面的圖書館服務，其精神風貌和遠見卓識令人敬佩。

The aim of the current article is to present a comprehensive and systematic review of the history of the National Southwest Associated University Library. The focus is on the construction process of the Library during 1937-1946. Toughened by working under the war-ridden and beleaguered conditions, and confronted with such challenges as tightening budgets and excessive scarcity of library facilities (books and reference materials, equipment and instruments) as well as personnel and supplies, library colleagues of Southwest Associated University endured great hardships in guarding book resources and disseminating knowledge together with other colleagues. They were all committed to preserving in library development, standardizing the library workflows, replenishing literature resources and developing various kinds of professional activities in libraries, which provided comprehensive library services for the teaching and scientific research of Southwest Associated University. Their spiritual outlooks and farsightedness are truly admirable.
