With planning of our social media activities in the second half of the year, our next Advent calendar is of course an integral part. This year, we want to use pictures with numbers from all over the world, preferably your pictures with numbers from all over the world. We have already posted a few examples under the hashtag #prom_zahlenausallerwelt (translation: numbers from around the world).

If you are currently traveling around the world, seeing numbers, taking photos and sharing them with the hashtag, we would love to repost these photos as a story first. At the end of October, we will then raffle off some “prometheus prizes” among the participants and ask everyone via DM whether we may use the photo for the #promvent24 Advent calendar. Are you in with your photos?

You can access our Instagram account directly via the left-hand navigation bar on our homepage. In addition to the updated icons for X , Mastodon, YouTube, Instagram, Facebook and Newsletter, the NFDI4Culture Registry Badge is now also integrated there. The registry is a service of the NFDI4Culture project, which collects and records metadata about existing research tools and data services that are specifically suitable for cultural studies. It provides a simple overview and prevents duplicate developments.
