The best way to find an ebook is via UCL Explore, as it gives you the opportunity to see all the titles to which UCL subscribes.
Unlike some other routes that are available online, access via Explore is completely legal and includes useful features, such as the opportunity to bookmark your search, save the ebook details into the referencing software of your choice, and check if the library has physical copies too. Once you have accessed the ebook, you can also create notes and share them with other UCL users.
Ebook records include a 'View Online' or 'Full text available' link. Click on this link to access the book.
Once you have found an ebook, you may be prompted for your UCL username and password. After you have entered these correctly, you will be able to access the ebook to read online or download.
