This article focused on the process of knowledge commodification, taking the “Index to Taiwan Periodical Literature System” as a case study, which included the analysis of the two journals: Mass Communication Research and Journal of Education & Psychology. It used the historical literature review and in-depth interview as research methods. The result showed that the critical issue of digitalization of journal article is tremendous licensing and administrative business rather than technical works, which made the publishing units cannot cope with these things. In addition to that public sectors of Taiwan didn’t provide any resources to help these units, so they in turn attempted to corporate with commercial companies to deal with administrative affairs, and then these companies obtained the exclusive rights of selling journal articles. As a consequence of this, gradually, commercial database had been replacd public database as the main access channel and that ordinary people were no longer open (and free) to access to these journal articles which are funded by public sectors.
