An important aspect of publishing is ensuring that our customers, such as university libraries, understand the value that our products have for them. One of the ways that we demonstrate value to librarians is to provide detailed usage reports about our content. Measuring usage is also important to the researchers and authors who publish with Cambridge, to help them demonstrate the impact of their work.

When content is shared in ways that don’t respect our policies, especially on third-party websites, it is difficult or impossible for us to measure the usage of that content. This makes it more difficult for librarians to make informed decisions about the value that our content has for them, and risks undermining the sustainability of the high-quality publications on which research and learning depend.

As an author we always permit you to share and re-use your final, published work in some ways, for example in subsequent publications of which you are also an author. Please see our permissions FAQs  for more information.

For content that is published Gold Open Access under a Creative Commons licence, anyone (including you) may share and re-use that content in accordance with the terms of that licence. Please see our information about Creative Commons licences.
