本文採取書目計量方法，分析《五四運動論著目錄初稿》一書中的1,567 筆文獻，探討臺灣1949 至2008 年所出版之五四運動文獻，在資料類型、出版年代、主題範圍、作者生產力的概況，其中更應用布萊德福定律，找出核心期刊，並分析其特質。本研究之目的有二：一、探討在臺灣出版之五四運動文獻的性質與特性；二、提供下一版《五四運動論著目錄》（定稿）具體之改進方向。研究結果歸納如下：一、五四運動文獻以期刊文章及圖書單篇為最多；二、出版年以1989 年五四運動七十週年時為歷年最高；三、主題範圍以社會科學類為最大宗，而科學與應用科學，研究文獻最少；四、五四運動期刊文獻分佈大致符合布萊德福定律各區比值1：n：n2；五、核心期刊有13 種，並以月刊為主，最多產的5種核心期刊為：傳記文學、中國論壇、中央月刊、聯合文學、大學雜誌；六、生產力前6名的作者有8 位，依序為周玉山、周策縱、余英時、林毓生、侯健、周陽山、夏志清及張玉法，皆為男性，且具相當學術地位，但研究生涯長短與生產力無關。展望未來之五四運動論著研究，若能擴大書目資料的蒐集範圍，例如將大陸出版之五四運動文獻，如清華同方中國期刊網資料庫，不同語文資料庫，如WorldCat 等，也列入書目資料檢索對象，相信應可獲得更全面性的研究結果。
