The Author must follow a good scientific practice, which means, e.g., that the same article cannot be published in another journal. However, the Author has the right to include Publishers’ version of the article to his/her own academic thesis, upload it to a personal website, and deposit it to an open institutional, scientific, or professional repository without a separate agreement. The Author has the right to publish an exact translation, provided that full bibliographic reference to the original article in Silva Fennica is given in the translation.
