Helda Open Books

Helda Open Books is collection of high quality open monographs and edited books by researchers and teachers at the University of Helsinki. Helda Open Books is a part of Helda, the open institutional repository of the University of Helsinki. The publications in the Helda Open Books collection receive a DOI, which increases their international visibility. In addition, the works are published under a Creative Commons license.

Helda Open Books is a publishing service provided by the Helsinki University Library.

Do you want to publish in Helda Open Books?

Helsinki University Library is interested in publishing your book in the Helda Open Books collection if the following conditions are met:

  • You have an affiliation to the University of Helsinki.
  • You have the rights to your work. Please note that rights may also be held by the layout designer, photographer, illustrator, and translator. The author must seek permission from the persons concerned before publishing.
  • You are able to send us a ready-to-publish pdf or epub file of the book. We will add license information and a DOI. If needed, the Helda Open Books cover is available to you (see an example). Unfortunately, we can't offer you the layout of the publications.
  • The works will be published under a Creative Commons license. Please note that if there are multiple authors or editors (e.g. edited books), permission to use the CC license must be obtained from all authors. In accordance with the University of Helsinki's principles of open publishing, we recommend the CC BY license.
  • Other things to consider:
    • Metadata enhances the discoverability of the publication. You can add keywords that describe your book, for example, by using vocabularies: we recommend YSO (General Finnish ontology).
    • Processing time for book proposals is case-specific, and it depends on e.g. available human resources. However, we strive to publish the works within a reasonable time.
    • Since the publications are free of charge for the end user, no copyright compensation accrues for a book openly published with CC licenses. Copyright compensation refers to various compensations paid through Kopiosto ry and Sanasto ry for copying, lending and using e-books and e-audiobooks. From the beginning of 2024, authors will be compensated for library use of e-books and e-audio books.

When the above things are in order, we will do an editorial evaluation. If the work passes it, a written agreement on publication will be made between the author and the library. If the work does not pass the evaluation, but other things are in order, the work may be published in Helda's books collection. If the author's goal is to publish an international, peer-reviewed and professionally edited monograph, please contact Helsinki University Press.
