I have not published my data within a year of deposition, can I extend the embargo period?


Yes. If no publication is identified within a year of deposition you will be contacted to confirm if the structure can be published as a CSD Communication or an ICSD Communication or if the structure is still intended for publication. If your structure is still intended for publication we will continue to store your data in trust for another year and if we fail to identify the publication within that subsequent year you will be contacted again.

You may now extend the embargo period yourself through our deposition services. To do this you will need to register for an account on our website and then when you log in go to 'My Structures'. You will see a list of your deposited structures and any that have a status of 'Unpublished' have not been made accessible to the public or added to the CSD or the ICSD. To look at the 'Embargoed Date' for these structures click on the 'Details' button. You will then be shown a Details page including the Embargoed Date and you can extend this date for another year by pressing 'Extend'.

You can extend your embargo period by a year at any time and through our deposition services you are also able to publish your data directly through the CSD or ICSD as a CSD Communication or ICSD Communication. To do this you will need to click the 'Publish in a Database' button on the details page described above.

Currently your data will not be disclosed to the public when your Embargoed Date expires and we use this date to remind you about any unpublished structures and ascertain from you what you would like to do with the data.
