EndNote Online does not work on Chromebooks.
Some students use Cite This For Me; however this is not a supported platform and the version of Harvard is not specific to the Harvard (BourneU) style that we use here, so you will need to check your references very carefully in conjunction with the BU Referencing guide.
The Library also has access to Cite Them Right which provides guidance and examples of different referencing styles, including APA 7th.
See our guide for referencing styles for help referencing.
If you need more help, just let us know.
