Abstract
Development of the Internet has opened a new epoch of post-Web or post-search engine period since around 1996 - 1997. Now "portal sites" are often referred to in substitution for search engines as to indicate the main entrance to the Internet, where various types of digital contents services are being provided. The paper in the first half gives an overview to these services including issues of digital libraries, electronic publication, copyright and MP3 formatted music. The trend seems to encourage authors to make self-publication or direct marketing of their works. Though informatics is expected to give an effective future view for the development of informatized society, the analyses appear to have been superficial. The establishment of the research area in informatics including its methodology would be presently most required.
