Operated by universities or research institutions, repositories allow scientific content to be archived and accessed. There are two types of repositories: institutional and disciplinary.
Repositories ensure documents are accessible long-term, unlike when published on personal or institutional websites.
Second publication in a repository takes places at the same time or following first publication. TU members can use TU Berlin's institutional repository – DepositOnce. Our self-archiving services can assist you with reviewing legal requirements.
We particularly recommend using disciplinary preprint servers for preprints, i.e. online publication before or at the same time as submission to a publisher. Preprints can also be published in DepositOnce.
