 \marginnote{In addition to the reference books, these lecture notes have found deep inspiration from~\cite{lectures:merry,lectures:teufel,lectures:hitchin} (all freely downloadable from the respective authors' websites), and from the book~\cite{book:abrahammarsdenratiu}.}
 \newthought{These lecture notes} are by no means comprehensive.
-As a reference you can use to the former course textbook~\cite{book:tu} or you can refer to~\cite{book:lee}: it is an incredibly good textbook and contains all the material of the course and much more.
-I have requested for~\cite{book:tu} book to be freely available via SpringerLink using the university proxy but this will take some time to become active.
-However, you can already freely access Lee's book via the University proxy on \href{https://link.springer.com/book/10.1007/978-1-4419-9982-5}{SpringerLink} and it will provide a very good and extensive reference for this and other future courses.
-The book~\cite{book:McInerney} is a nice compact companion that develops most of this course concept in the specific case of $\R^n$ and could provide further examples and food for thoughts.
-A colleague recently mentioned also~\cite{book:lang}. I don't know this book but from a brief look it seems to follow a similar path as these lecture notes, so might provide an alternative reference after all.
+As a reference you can use to the former course textbook~\cite{book:tu} or you can refer to~\cite{book:lee}.

+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} 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}.
 In some sense I would like this course to provide the introduction to geometric analysis that I wish was there when I prepared my \href{https://www.mseri.me/lecture-notes-hamiltonian-mechanics/}{first edition} of the Hamiltonian mechanics course.
