We use in-text citations for all the same reasons we use references. The important difference is that in-text citations are found in the body of your work, while references are found in the list at the end of your work.
In-text citations are used to point out to the reader exactly which pieces of information, ideas, thoughts images etc. were created by someone else.
This is a requirement of the IB (Academic Integrity). It is also the ethical and moral thing to do and helps us to avoid plagiarism and copyright infringements.
Also - Using in-text citations helps your teachers to see that you have done the research and understood the information, giving your work more weight!
Chicago uses two types of citations:
This page will only be discussing the Notes and Bibliography Style.
To cite a source using Chicago style Notes and Bibliography, you need to place a superscript number, beginning with ¹ at the end of a sentence or clause, after all the punctuation. This superscript number then corresponds to a numbered footnote in the footer at the bottom of that page, or endnote in the footer at the bottom of the final page, where you include the reference note for the resource as found in the Reference List at the end of your work. The next citation gets the next superscript number. No matter which page it is on, the numbers continue un sequence. NOTE: If you use the 'Insert Footnote' function in your document, this process should be reasonable easy.
There are two types of notes: Full Notes or Short Notes.
The first time you refer to a resource you include a Full Notes which gives the author's name(s) and the title of the text with the publication details in parentheses. This can vary according to source type. If you quote a source or refer to information from a specific passage from a source that has an unchangeable location indicator, include the page number or location.
Subsequent footnotes for the same resource take Short Note form. Short notes only include the author(s), title and location information in the format seen in the final Reference List. Titles of longer than 4 words can be shortened, but must retain the keywords to be easily recognizable.
According to IB Requirements, you must include the Reference List at the end of your work.

Dragons are "always portrayed as reptilian" although there are a wide range of reptiles influencing the different portrayals.²
