This is at the same time an advantage as the documents reported can directly be accessed. In addition, the data base is freely accessible. Yet another on-line database is the Collection of Computer Science Bibliographies . Suppose that you have encountered a publication relevant to your research. It may be worthwhile to see whether the authors have more relevant publications.
Many academic researchers have their list of publications on-line.
The worldwide list of universities may also be useful to locate web pages of authors and their research groups. Check the catalog of the University of Twente Library . You can search using authors, titles, or ISBN numbers of books and conference proceedings, titles or ISSN numbers of journals, etc. If present, the catalog will tell you in which of the university libraries the item can be found. Journals are identified by a number after the location code.
