Many initiatives for collective financing of Diamond Open Access publications struggle to gain sufficient attention by potential supporters. The new service “Diamond Funding Navigator”, developed and provided by Technische Informationsbibliothek (TIB), helps by providing a comprehensive overview of those initiatives: increased visibility of the offers, as well as embedded possibilities for analysis, can lead to increased participation in these consortia and thus ultimately facilitate the achievement of their funding objectives. In the poster, we present the concept of the Diamond Funding Navigator and highlight some benefits: Since many potential supporting institutions find it difficult to evaluate the extent to which their researchers are involved in the publications to be funded, we have implemented the possibility to retrieve their publication data from OpenAlex for these specific publications. On our poster, we will also provide insights into the technical basis on which the tool was developed. Conference participants are invited to get involved by exploring the Diamond Funding Navigator, giving feedback and (if in the position to do so) providing information about new consortia for Diamond Open Access publications.
