Hi all. 
I'm looking for english books with a good coverage of distribution theory.
I'm a fan of Folland's Real analysis, but it only gives elementary notions on distributions.
Thanks in advance.



Good books on theory of distributions
Grubb's recent *Distributions And Operators* is supposed to be quite good. 


There's also the recommended reference work, Strichartz, R. (1994), *A Guide to Distribution Theory and Fourier Transforms* 


The comprehensive treatise on the subject-although quite old now-is Gel'fand, I.M.; Shilov, G.E. (1966–1968), *Generalized functions, 1–5,*. 


A very good,though quite advanced,source that's now available in Dover is Trèves, François (1967), *Topological Vector Spaces, Distributions and Kernels* That book is one of the classic texts on functional analysis and if you're an analyst or aspire to be,there's no reason not to have it now. But as I said,it's quite challenging. 


That should be enough to get you started.And of course,if you read French,you really should go back and read Schwartz's original treatise.
