We are currently experiencing problems with resources that we link to via DOI. A DOI (Digital Object Identifier) is a unique alphanumeric string that is used to identify content and provide a persistent link to its location on the internet. An example of a resource that links via DOI is this, http://idpproxy.reading.ac.uk/login?url=https://doi.org/10.1017/9781316338773.

Unfortunately one of our authentication methods is currently interfering with such linking and preventing users from accessing content. If you find a link with this problem it will take you to a webpage with a ‘Bad Gateway’ error message. This is affecting resources that are using our Proxy that link via DOI, and as such may appear in Talis, Enterprise or Summon. We are aware of the urgency of this problem and are working with the company that manages this authentication system to resolve the situation. In the meantime we have changed links in Talis and Summon so that they no longer authenticate with the proxy, these changes may take up to 48 hours to complete. Once on a platform you may need to login to a resource via the institutional sign in.

If you come across such an error message you can still access the resource by using our A-Z databases list to search for the platform the eBook or article is on, and then search the database using the title or author to find the resource.

I apologise for the inconvenience caused.
