The purpose of this paper is to evaluate the functionality of the particular epistemological schools with regard to the issues of users with visual impairment, to offer a theoretical answer to the question why these issues are not in the center of the interest of information science, and to try to find an epistemological approach that has ambitions to create the theoretical basis for the analysis of the relationship between information and visually impaired users.

The methodological basis of the paper is determined by the selection of the epistemological approach. In order to think about the concept of information and to put it in relation to issues associated with users with visual impairment, a conceptual analysis is applied.

Most of information science theories are based on empiricism and rationalism; this is the reason for their low interest in the questions of visually impaired users. Users with visual disabilities are out of the interest of rationalistic epistemology because it underestimates sensory perception; empiricism is not interested in them paradoxically because it overestimates sensory perception. Realism which fairly reflects such issues is an approach which allows the providing of information to persons with visual disabilities to be dealt with properly.

The paper has a speculative character. Its findings should be supported by empirical research in the future.

Theoretical questions solved in the paper come from the practice of providing information to visually impaired users. Because practice has an influence on theory and vice versa, the author hopes that the findings included in the paper can serve to improve practice in the field.

The paper provides theoretical anchoring of the issues which are related to the inclusion of people with disabilities into society and its findings have a potential to support such efforts.

This is first study linking questions of users with visual disabilities to highly abstract issues connected to the concept of information.

The development of the World‐Wide Web has caught the imagination not only of professional computer users, but also of large sections of the general public: news and feature items concerning aspects of the Internet abound in the popular media, and these commonly specify the Web as the technology of choice for accessing a wide variety of information resources.

A survey carried out during 1998 investigated the use of the World Wide Web for user education in 68 UK university libraries. Almost three‐quarters of the libraries surveyed make use of the Web for this purpose. The Web is used as a supplement to existing user education, in order to support independent, student centred learning and to reach parttime and distance learners. Just ten percent of user education is delivered solely via the Web, but libraries indicated that use will grow in the future. It was found that greater use is made of the Web for information skills training than for library induction. The authors suggest a number of reasons why more use is not being made of the Web for user education and propose future developments in this area. Web‐based instruction is unlikely to completely replace traditional methods, but it can be used to supplement and extend existing provision.

The concept of information is central to several fields of research and professional practice. So many definitions have been put forward that complete inventory is unachievable while authors have failed to reach a consensus. In the face of the present impasse, innovative proposals could rouse information theorists to action, but literature surveys tend to emphasize the common traits of definitions. Reviewers are inclined to iron out originality in information models; thus the purpose of this paper is to discover the creativity of authors attempting to define the concept of information and to stimulate the progress of studies in this field.

Because the present inquiry could be influenced and distorted by personal criteria and opinions, the authors have adopted precise criteria and guidelines. It could be said the present approach approximates a statistical methodology.

The findings of this paper include (1) The authors found 32 original definitions of information which sometimes current surveys have overlooked. (2) The authors found a relation between information theories and advances in information technology. (3) Overall, the authors found that researchers take account of a wide variety of perspectives yet overlook the notion of information as used by computing practitioners such as electronic engineers and software developers.

The authors comment on some limitations of the procedure that was followed. Results 1 and 3 open up new possibilities for theoretical research in the information domain.

This is an attempt to conduct a bibliographical inquiry driven by objective and scientific criteria; its value lies in the fact that final report has not been influenced by personal choice or arbitrary viewpoints.
