# How can the Diamond route operate without publication or reading fees?

Journals and publishing platforms that operate according to the Diamond model are mostly funded or subsidised by non-commercial sponsors — universities, learned societies, libraries, etc. — and allow authors to retain their copyright through the use of open Creative Commons licences.

Increasingly, these journals benefit from library support to ensure their sustainability. The Cantonal and University Library of Lausanne (BCUL), in collaboration with the University of Lausanne and the University Library of Medicine, has established a Diamond fund to support journals and platforms deemed important to the communities served by these institutions (see details on the [BCUL Diamond Fund page](https://www.bcu-lausanne.ch/blog-librairie/fonds-open-access-diamant-unil-chuv-unisante-hep-vaud/)).

When an author from the University of Lausanne publishes in a Diamond journal, they indirectly contribute to its support, since it will benefit from financial backing from the BCUL.
