HARVARD Referencing System
(adapted simplified version of the guide available at

A full list of references should be provided at the end of the text. The recommended format is an adapted Harvard system. Unpublished results and personal communications should not be present in the list of references. They may appear in the main text and in the footnotes. Abbreviations of Bulgarian and foreign journals should follow the standard published on the journal website.

Reference in text

  • one author/name (Insoll 2007)
  • two authors (Gurova, Nachev 2008)
  • multiple authors (Bonsall et al. 2010)
  • with direct quotation on a page (Nikolov 1996, 7)
  • multiple publications and authors – in chronological order (Perlès 1992; 2001; 2004; Rosen 1997, fig. 12; Chapman 2000)
  • in case of authors in Cyrillic script, they are listed first followed by authors in Roman script and in accordance with the rule explained in the paragraph above outlining multiple publications

Reference list

The references should be arranged alphabetically by the first author’s family name and by year of publication in case of multiple publications by the same author(s). In case of papers written in non-Roman script, if there is an English title in the summary, it may be used instead. If there is not such a summary, the author’s name and the paper/book title must be transliterated in Roman script; the original language of the cited reference should be noted in parentheses at the end of the paragraph, e.g. (in Bulgarian). For papers accepted to be published in Bulgarian, obligatory transliteration in parentheses is required after the original in Cyrillic script for all publications in the reference list.
Transliteration is performed according to the Transliteration Act and its Regulation. There are suitable online programs that can be used, such as

NB! Authors should spell their name as it was introduced and known in previous publications, even if the transliteration tools offer another option.

All publications with online access should contain DOI link (or URL address), as follows:
