How to find Open Access publications?
Journal article, anthology article, research report, or entire book – any type of publication can be Open Access.
And just as colourful as the types of publications are the places where they can be stored: from the personal homepages of scientists to the document servers of universities or institutions to the websites of publishers to platforms for journals and books of all disciplines.
In KatalogPlus contains many Open Access publications, but still only a fraction of all publications worldwide. To increase your chances of finding what you are looking for, it is worthwhile to search in special directories as well.
