This will bring up a menu which provides options for exporting the resource details in multiple formats.
Follow the instructions provided once you have clicked your choice to export the entry details in your chosen format.

I've got more questions about exporting references
The Academic Librarians will be happy to help you work on exporting and referencing. You can see your librarian face to face or online for a tutorial. You can also contact them by email at librarian@northampton.ac.uk
