Springer’s book-chapter sharing policies Last year I submitted an article to a peer-reviewed book to be added as a chapter. Finally, my article got accepted and it is ready for publication. The publisher is going to be Springer. 

I would like to share a copy of my article on my website and with my colleagues through the university repository. My concern is that I am not sure whether I can do it or not.

Springer has some sharing policies for journal articles. You can share a preprint version with a link to the published one (via DOI). However, it is not clear whether I can do that with a book chapter.

Can someone with similar experience clarify this?
This is the answer I got from Springer for a smiliar question:

"Thank you for getting in touch. Springer doesn’t have a green OA policy at this time. Chapter authors would need to choose the gold OA route. We are able to offer gold OA for chapters already published (retrospective OA) in cases where the authors need to fulfill a funder OA mandate.

Our policies regarding OA books can be found here: https://www.springernature.com/gp/open-research/policies/book-policies 

Please feel free to be in touch if you have further questions—I’m happy to help."
