The present edition “Media and Communications: Scientific Bibliography 1990–2022” was prepared on the occasion of the 70th anniversary of higher education in journalism in Bulgaria (1952–2022) and was initiated by Prof. Dr. Vesselina Valkanova, Dean of the Faculty of Journalism and Mass Communication at Sofia University St. Kliment Ohridski. This publication is the first topical bibliography of the scientific publications by university scholars and researchers in Bulgaria regarding the specific topics of Communication, Media, Journalism, Public Relations and Publishing. For the first time since the beginning of democracy in 1990 the scientific foundations for the education of journalists and other media and communication professions in Bulgaria has been outlined. It should be noted that in all former socialist countries in Europe the period after 1990 is considered as the more significant one in the field of journalism training. The methodological thesis, with which we have operated, regards a bibliography as a cumulative book of the condensed knowledge about a certain field of life and also as a mediator serving the knowledge-based society. The thesis regarding bibliography as a media has been theorized in two scientific articles by Milena Tsvetkova – “The Searching Man: The Reputation of Bibliographic Culture” (2005) and “Bibliography as a Media” (2005). At the beginning of the publication there is a Preface by the Dean of the Faculty of Journalism and Mass Communication at Sofia University St. Kliment Ohridski and an Introduction to the bibliography. The bibliographic database is structured into two main parts. The first presents the bibliographic corpus. The material is systematised into three sections: edited collections and conference proceedings, monographs and research studies and articles. The bibliographic descriptions are ordered by year of publication. The second part of the edition represents an aid for scientific research offering three indexes for informational search by descriptors – Author Index, Index of Periodicals and Subject Index. The Subject Index is structured by way of subordination – through groups of collective and partitive terms and also in separate simple or descriptive subject headings. There have been registered a total of 6480 bibliographic entries, 5917 of which are in Cyrillic and 563 are written in Latin script. The total amount of edited collections and conference proceedings is 579 (542 in Cyrillic and 37 in Latin script). The total amount of monographs is 1225 (1196 in Cyrillic and 29 in Latin script). The total amount of research studies and articles is 4676 (4179 in Cyrillic and 497 in Latin script). The total amount of the names with author`s responsibility is 2629 (2372 in Cyrillic and 257 in Latin script). The total amount of periodicals, in which the scientific works have been published, is 394 (282 in Cyrillic and 112 in Latin script). The total amount of subject terms in the content range of the bibliography is 2245 (1806 in Cyrillic and 439 in Latin script). As a result of the applied bibliographical approach we have compiled a representative collection of publications of the Bulgarian science of media and communications. In its completed form the edition “Media and Communications: Scientific Bibliography 1990–2022” could be regarded as a model of the scientific knowledge in the field of media and communications and as a main source and beginning of any new research. By its essence it is а scientific tool, which aims to support the research and educational activities in the history, theory and methodology of communication and media, in journalism, public relations, publishing, etc. and the necessary in such cases bibliometric analysis. The scientific specifics of such kind of editions allow for their use to be encouraged in the information and the monitoring activities of media, communication, and library organizations. This publication was made possible through the financial support of the National Science Fund with the Bulgarian Ministry of Education and Science under grant of the program “Bulgarian Scientific Periodicals – 2022” (Contract No. KP-06-NP3/56, dated 22.11.2021).
