I'd like to learn the basics of Hirsch-Smale immersion theory. What sources are best for this? My background is mostly topological; however, many of the sources I've found on the internet focused on later work of Gromov on the h-principle which seems more analytic than I would like.



Where should I learn about immersion theory?
M. Weiss has a very good survey on his homepage:
<http://wwwmath.uni-muenster.de/u/mweis_02/papers.html>
called "Immersion theory for homotopy theorists". I also like very much M. Adachi's book "Embeddings and immersions". I think both are very good starters if you have a topological background. 


J. Francis has also some notes on his homepage:
<http://www.math.northwestern.edu/~jnkf/classes/hprin/>
on a course about the h-principle that can be helpful. 


Also Eliashberg and Mischachev's book "introduction to the h-principle" is definitively a very good book.
