 You should have access to both books via the University library and, in addition, Lee's ebook can be downloaded via the University proxy on \href{https://link.springer.com/book/10.1007/978-1-4419-9982-5}{SpringerLink}.
 
 The book~\cite{book:McInerney} is a nice compact companion that develops most of the concepts of the course in the specific case of $\R^n$ and could provide further examples and food for thoughts.
-The books~\cite{book:nicolaescu}\footnote{Beware of typos, there are many.} and~\cite{book:crane}, freely available from the authors' website, are not really suitable as references for this courses but provides fantastic resources for the readers that want to dig further and see where the material discussed in the course can lead.

 Finally, a colleague mentioned~\cite{book:lang}. I don't have experience with this book but from a brief look it seems to follow a similar path as these lecture notes, so it might provide yet an alternative reference after all.
 
 The idea for the cut that I want to give to this course was inspired by the online \href{https://www.video.uni-erlangen.de/course/id/242}{Lectures on the Geometric Anatomy of Theoretical Physics} by Frederic Schuller, by the lecture notes of Stefan Teufel's Classical Mechanics course~\cite{lectures:teufel} (in German), by the classical mechanics book by Arnold~\cite{book:arnold} and by the Analysis of Manifold chapter in~\cite{book:thirring}.
