I've for some time been learning elementary functional analysis from the book Introductory Functional Analysis With Applications by Erwine Kreyszig.
Although Kreyszig's presentation is mostly accessible for a person with not-a-very-strong background in analysis, there often are occasions where, as I feel, he sacrifices rigor and detail in the interest of simplicity of the presentation. And, sometimes he is too verbose; sometimes he is perhaps not explicit enough. Besides, Kreyszig's text, as far as I know, is not being followed at those "elite" places like the MIT who offer such anciliary support as the MIT OCW.
So I would like to have another text that covers the same (or roughly the same) material as does Kreyszig (and preferably a text that covers this material in a more rigorous and explicit manner).
Can the esteemed Math SE community suggest any such text?
Is there any place on the Internet where I can access notes of courses taught using Kreyszig's text, especially the first four chapters?
For those who haven't got a copy of Kreyszig, here is the link to a page where it can be accessed (and perhaps can also be downloaded) for free.
