Searching on the net I couldnt find any recent lecture/course notes on Morse Theory. I found an old set of notes (<http://www.math.toronto.edu/mgualt/Morse%20Theory/mfp.pdf>) by Mike Hutchings and these incomplete notes by Ralph Cohen (<http://math.stanford.edu/~ralph/morsecourse/biglectures.pdf>)


[..I really want a reference which has a detailed description of the ``gradient flow line" perspective as in the chater 4,5,6 of Ralph's notes. Just that Ralph's notes are very hard to follow given that all the diagrams are missing!..]


I found this book that has been made legally freely available by the author, <https://www3.nd.edu/~lnicolae/Morse2nd.pdf> and I have read quite a bit of the old book by Milnor. 


* Are there other other good references (particularly lecture/course notes) that I am missing?



What are good Morse Theory lecture notes and books?
If you are looking for the classical approach to Morse theory, I feel nothing beats Milnor's book on the subject:



> 
> Milnor, J.
>  Morse theory. 
>  Annals of Mathematics Studies, No. 51 Princeton University Press, Princeton, N.J. 1963
> 
> 
> 


For the Morse homological approach, i.e. counting flowlines, I really like Weber's [paper](https://arxiv.org/abs/math/0411465) on the subject:



> 
> Weber, Joa
>  The Morse-Witten complex via dynamical systems. 
>  Expo. Math. 24 (2006), no. 2.
> 
> 
> 


Another standard reference is the book of Banyaga and Hurtubise. 



> 
> Banyaga, Augustin; Hurtubise, David
>  Lectures on Morse homology. 
>  Kluwer Texts in the Mathematical Sciences, 29. Kluwer Academic Publishers Group, Dordrecht, 2004. 
>

A book that is tough to read, but is a gateway to Floer theory is Schwarz' book. 



> 
> Schwarz, Matthias
>  Morse homology. 
>  Progress in Mathematics, 111. Birkhäuser Verlag, Basel, 1993.
> 
>

I heard good things about the book of Audin and Damian, but I have not read it. 



> 
> Audin, Michèle; Damian, Mihai
>  Morse theory and Floer homology. 
>  Translated from the 2010 French original by Reinie Erné. Universitext. Springer, London; EDP Sciences, Les Ulis, 2014.
