Up-to-date academic resources on CSR and Open Source involvement

I am considering writing my Master Thesis on the following topic "CSR in IT: Open Source Involvement and Its Benefits for the Company". I will be proving why OS can be considered a CSR activity and various ways of how it can help companies. The main problem I am running into is the lack of academic resources on the topic. Most of the books on Open Source seem to be outdated (early 2000s) and there is very little said about Open Source involvement in the CSR context. Can anyone suggest books/academic studies on this topic? Case studies are also welcome. Thanks!
