Not every book can be an ebook

It is a sad fact universally acknowledged that unfortunately, not every print book in our collections or out there in the world is actually available as an ebook! So what can you do to source a digital copy of an essential book, when the library print collections are not accessible due to Lockdown rules?
Firstly, double check on DiscoverEd for the title you need. You can filter your search results by “online resource”.
Then consider whether the Scan & Deliver service could be useful, if you just need one chapter, or 1 journal article. Please note that due to UK Copyright law and the CLA licence under which all Higher Education institutions operate, we are only permitted to copy 10% of a book, (or 1 chapter, whichever is greater), or 1 journal article from a journal issue. This is not an arbitrary decision by the library! You can see more about Copyright restrictions here:
Consider using the Inter Library Loan service to get digitised journal articles or book chapters.
If you need a complete book, consider whether you can purchase a cheap second hand copy, eg using abebooks or another out of print book seller.
You could also try the various online archives of (usually out of print) books. Here is a list, in no particular order:
1: World Digital Library
2: Project Gutenberg
4: Internet Archive
5: Directory of Open Access Books (DOAB)
6: Open Textbook Library
8: Directory of Open Access Journals (DOAJ)
For more information about open access educational resources and advice, take a look at the University of Edinburgh Open.Ed resource.
You could also explore the digital collections of the British Library and the National Library of Scotland.
