Formatting: Literature and references

In-text references and the reference list at the end of the paper should be prepared according to the Council of Science Editors (CSE) documentation Name-Year (N-Y) system.

In-text references should be cited in the form of the author’s last name and the year of publication, in parentheses, e.g. (Nowak 2017). When a paper has two authors, it should be cited in parentheses as follows: (Nowak and Smith 2017).

When a paper has more than two authors, the first author’s name should be followed with “et al. and the year of publication, e.g. (Nowak et al. 2002). While references occur that are not identified by the authors’ names and year, use a, b etc. after the year (Nowak et al. 2002a; 2002b).

When you cite multiple works by different authors, put the sources in chronological order from oldest to most recent (and alphabetically, if published in the same year). Separate studies by semicolon: (Nowak et al. 2008; Smith et al. 2016).

The list of the papers cited (Literature) is organized alphabetically according to the last name of the first author and not numbered. The reference list is organized alphabetically by author’s last name. When there is more than one work by the author, those works are organized chronologically. Authors’ first names are rendered as capitals after their surnames as in an example: Nowak BS, Smith J, Coward PP. Papers with one only author are listed in chronological order (the earliest first); papers with two authors are listed alphabetically according to the last name of the first author and by the last name of the second author; paper with three or more authors appear as those with two authors and are listed chronologically.

Only the first word of a book or article title should be capitalized. Titles are not italicized. However, species names are italicized.

Here, you find an example: Nowak PP, Smith J. 2011. Occurrence of OxyR in the hydrogen peroxide stress response of Pseudomonas aeruginosa. J Clin Microbiol. 75(12):534-536.

The journal article on the Internet should be cited as follows: Nowak NG, Smith TY, Howard FG. 2017. Archaea and bacteria. Biol Microbiol [Internet] [cited 2017 May 15]; 158(1):1-25. Available from: doi:17.1111/j.1744-7348.2010.y

References for books follow should be provided in the order: Author(s). Year. Title. Edition. Place of publication: Publisher. Extent. As in an example: Nowak C, Smith P, Howard M. 2008. Virulence factors of Pseudomonas aeruginosa. Warsaw: PTM Press 203 p.

References for chapters or other parts of a book should be provided in the order: Author(s). Year. Chapter title. In: Editor(s). Book title. Place of publication: Publisher. Page numbers for that chapter.

Use the proper journal title abbreviations (ISO4 standard) as indicated in the PubMed Journal Database.

The Editorial Office strongly recommends to use the dedicated software to manage and edit citations and literature. To easily adjust or change references according to the PJM requirements choose a CSE citation style (N-Y option), which is build-in in these programs. List and comparison of reference management software may be viewed e.g. at the Wikipedia site.
