As POST is an open access journal, this means that anyone who can access the Internet can freely download and read the journal. There are no commercial interests for Linköping University Electronic Press. There are no charges for publishing authors.
The core idea of open access is that copyright remains with the author(s). However, we publish with the agreement of the author that if she or he decides later to publish the article elsewhere, that the publisher will be notified, prior to any acceptance, that the article has already been published by POST.
When publishing with POST, it is with the agreement of the author that if they make their article available elsewhere on the internet (for example, on their own website or an institutional website), that they will do so by making a link to the article as published in POST using the Digital Object Identifier (DOI) number of the article and acknowledge in the text of the site that the article has been previously published in POST.
