Hurray! You have found a book with valuable information on your topic!
Now you just need to let your audience know where this information that you are using for your presentation came from.
You will compile a bibliography or reference list. For each source you will write a citation.
Citation styles define:
- which pieces of information about your source to include
- how to order and format them.
You want to send your audience to the exact same publication that provided the information to you! Writing citations is not rocket science but you need to pay attention to detail!
