Abstract : There are many methods to access the Internet. Therefore, legacy contents should be able to be displayed on those information terminals in readable form. But many of those contents displayed on mobile terminals are hard to understand or even not readable because 1) those contents are
designed to display on PC's large display, and 2) small screen of mobile terminals. In order to display those contents on mobile terminals, those contents should be rebuilt or converted into readable form. But it is inefficient to rebuild those contents by hand for information terminals separately. In this paper, we survey how Internet contents for PCs are automatically converted into readable contents for mobile terminals.

Abstract : The Internet may be a tool that greatly expands the possibility for reference service in school libraries. However, to use the Internet, it is essential to understand the system of information retrieval and also to learn this new way of thinking about information retrieval. In addition, since the quality of information on the Internet is not necessarily guaranteed, careful evaluation of information is essential. School libraries today are using information on the Internet not only for reference service, so it is also very important to educate students about information retrieval in the process of providing information literacy instruction. In educating students about information retrieval, instructors should stress the way of thinking about information retrieval, especially the preparatory stage.
