Self-archiving your publications in the University’s repository is an easy form of open access publishing. Doctoral researchers employed by the University are expected to comply with the principles of open access publishing, but the University strongly recommends that all doctoral researchers do so.
Self-archiving ensures that your publications are not placed behind a paywall and guarantees the long-term preservation and use of publications. Self-archived publications receive a permanent URL that also allows citation.
Self-archiving in the University’s publication repository is free of charge. Researchers use the Tuhat system to store their publications. You should self-archive your publications while updating the related information in your Tuhat profile. Helsinki University Library offers support and guidance for self-archiving and can, if necessary, self-archive your publications on your behalf.
Please note that the original publisher also has a say on when the self-archived publication can be made available. For further information on the practices of various science publishers and the length of time publishers set for self-archiving (embargo periods), please see publisher websites, contact Helsinki University Library or access the open SHERPA/RoMEO database which lists the self-archiving practices of various publishers.
The self-archiving of articles included in an article-based doctoral thesis should be done no later than when the final thesis is about to be published. However, we recommend that you self-archive your articles as and when you publish them because you will have a great deal of other things to do as the public examination of your doctoral thesis approaches.
