Starting from the year 2016, the journals published by the Polish Botanical Society will be only available as an online edition.
Therefore, the page numbers will be no longer used for citation purposes. Every article will contain citation schema with the unique article number included (see the screenshot below), which replaces pagination. Additionally, the article number will be the last part of the updated DOI pattern.
The Monographiae Botanicae series will be still available in print and online. It should be cited as a book in a series, e.g (using the references format from the PBS publications):
Świderska-Burek U. Cercosporoid fungi of Poland. Wrocław: Polish Botanical Society; 2015. (Monographiae Botanicae; vol 105). http://dx.doi.org/10.5586/mb.2015.001
