I've added the three references to our .bib file.
Only point was the Introduction to Data Science book was a bit stranger to reference as I wasn't sure of the publisher for the online version so I just went with Leanpub. However, I wasn't sure where we referenced it in our .Rmd file, so currently it isn't being referenced. But this can be added in just by [@IDS] in the file.
