I’m seeing an error message that says the ebook is locked/being used by another person. What does this mean?

For licensing reasons, some ebooks can only be used by a set number of people at the same time. If too many people try to access these ebooks simultaneously, the last person to open the ebook will see a message telling them it is currently in use. You will then need to wait for the first person to stop using it, before you can access it. For further support in accessing your reading materials, please raise an enquiry with the Library team via Surrey Support, selecting 'Library Resources' as your enquiry topic, and we will investigate for you.
