Zotero is a tool that you can download to assist you store, keep track of and organise your references for citations. It can be used for all referencing styles, including APA 7th. The really useful thing about Zotero is that it captures the data of a source with the click of a button. It then saves that data in your Zotero library and taps into it to automatically create a correct citation.
You need to download the Zotero software to your machine. Please see the screencast below for assistance with this. Please note you need to download both the Zotero program AND the connector to help you capture the data from electronic resources.
It does take a bit of use to get the hang of Zotero, but once you do, it becomes second-nature and is quite straightforward to use. And as with anything, please check all citations generated by Zotero to ensure there are no problems. Nothing beats the human eye for this kind of crosschecking.
Please note that you need to choose APA 7th for your Elective Geography assignments in your Zotero preferences.
