Do you want to engage with Open Science?
When possible, use and cite existing public data
Whenever feasible, share your research data through trusted repositories. General-purpose repositories and domain-specific ones
are available on the web. Make sure you share metadata as well
If you use software code as part of your research cycle, release the code. Specify the open source license you intend to use, and link the
readers to a stable repository that hosts the code
Post free copies of your research articles online. Most journals allow this, sometimes after an embargo period of 6-12 months
Post preprints of your research manuscripts online, ideally at the same time of official submission to a journal
When possible, choose an open access journal as venue for your scientific articles. Keep in mind that subscription journals also offer an
open access solution, upon payment of extra fees
