| Abstract: | 引文索引資料庫中期刊引用數據之計量指標是學術評鑑最常使用之準則，本文首先以Thomson Reuters 建置為學術界與圖書資訊服務界廣為使用之JCR(Journal Citation Reports, JCR)為基礎，並旁及在網路化與數位化環境下，所產生的引文索引資料庫與系統，計有Elsevier 的Scopus系統與西班牙SCImago Group。針對其所開發之指標內容及其應用與限制，加以探討，進而希冀提供學術評鑑單位、圖書館、期刊出版者、資料庫製作者、作者與使用者之參考。

In addition to JCR of WOS, Scopus supplies other unique journal impact indicators, i.e., % not cited, source normalized impact per paper (SNIP) and SCImago journal rank (SJR).
