You can read all content published in journals on Publicera free of charge, and no login is required. What you are allowed to do with the content of a journal, in addition to reading, can vary however, and depends on which copyright rules apply.

If an article is freely available, the journal's article pages state which Creative Commons (CC) license applies:

Check which CC license the journal uses if you want to reuse or remix articles and other material.

If the article page does not indicate which CC license applies, other copyright rules apply. You are then responsible for finding out which rules apply for that material. If you want permission to copy, distribute or otherwise use this material, please contact the journal's editors. The National Library of Sweden is not responsible for further distribution of this material, rather the respective journal owners are.
