The purpose of this study is aimed at the citing behavior of Internet-based electronic resources used on the scholarly journals, in the field of librarianship, and others scholarly journals published under the auspices of the National Science Council (Taiwan) in 2000. By using citation analysis, this study has cross-examined different characters (variables) of each Internet resource, such as accessibility, availability, URL location variability, linking protocol, etc., to analyze how and why scholars cited the varied Internet sources. The results are as follows: the percentage of network citation on scholarly journals, in the field of librarianship, reaches 7.36%, however the network citation rate in other scholarly journals published under the auspices of the National Science Council (Taiwan) is only 0.02%. As well as the "re-accessible rate of network citation" on library journals is 53.99%, in comparison to 40% from the other sample sets. This study also analyzes the possible factors which may affect the citing behavior of scholars, including the frequency of Internet use, the topic of articles, the advances in the Internet industry, the citing formats of the Internet-based electronic resources, "the re-accessible rate of network citation", the quantity of scholarly Internet-based electronic resources, and the authority and reliability of the Internet-based electronic resources.
