Thank you for your interest in making the DSI even more comprehensive. We have set up a form for new data entry.  Any external submission will be sent to the database compiler. It will be carefully verified and standardized (if necessary) before being released online.
Please click here to submit a new entry.

Initially please only submit a few entries and contact us to get feedback. A maximum of 50 new suggestions can be processed at a time – please await their inclusion before submitting more.

Thank you in advance for your interest and support of our interactive project!
