About and editorial policies


Historia naturalis bulgarica is the peer-reviewed journal of the National Museum of Natural History at the Bulgarian Academy of Sciences. We publish scientific contributions on geology, palaeontology, botany, zoology, and original articles on the history of natural science, information about museum collections and others. Currently all papers are published in English.

All manuscripts will be subjected to peer review before acceptance by at least two peers qualified to evaluate them.

Open access

The periodical provides immediate open access to its content. All content is freely available without any charge. Everyone is allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles, or use them for any other lawful purpose, without asking prior permission from the author or the publisher. Making research freely available to the public supports a greater global exchange of knowledge.

Publishing schedule, versions, reprints

The periodicity is at least one volume per year. Since 2018, volume 25, Historia naturalis bulgarica is published online only and articles in *.PDF are available free of charge.

Submitting a manuscript to Historia naturalis bulgarica, the authors certify that:

The editors can check the manuscripts for possible plagiarism using ‘Antiplagiat’ or similar service. Because plagiarism is a theft of intellectual property all manuscripts submitted to Historia naturalis bulgarica which contain significant non-attributed texts copied from other articles will be rejected. When there is a case of plagiarism in an already published article, an announcement will be published in both journals and the paper can be retracted, but only after a very careful consideration by the editors. The PDF document of the retracted article will remain on the site, clearly marked ‘Retracted’.


Currently the entire publication process is supported by the National Museum of Natural History. There is no article processing charge (APC) or any other fee charged to authors.
