This paper introduces two main current dynamic link systems, SFX Context Sensitive Linking based on OpenURL and CrossRef based on DOI. It points out that SFX is localized, interoperable and customizable. It can give users appropriate links to the availability of resources. The CrossRef links point directly to the publishers’ literature and information pages with accurate and stable links but not suitable for users to obtain Final document Discuss the problems of CrossRef link and analyze the characteristics of SFX. Based on this, we put forward the method of combining SFX and CrossRef / DOI, and point out that this will enhance and perfect the link function of SFX and solve the problem of appropriate CrossRef / DOI link.
