If you make your publications freely available on the Internet - their usage and number of citations will increase. At Lund University you are recommended, when possible, to publish the full text of your research publications in Lund University Publications (LUP). If you do, your research will be much more visible than if you don't, through Google, the Lund University website and the Swedish national database of research publications, Swepub.
It is also important that you are aware that your research might be funded by an organisation that requires you to make your research freely available. You can check policies from both publishing houses and research funders below in SHERPA RoMEO and SHERPA JULIET.
