    Analysis is really not my thing, but this book saw me through occasional difficulties that i had both in undergrad and graduate courses. I recommend it.

    Un libro clásico de 1966 con edición de Dover del 2000.
    Me parece que el detalle a resaltar del libro, es que es un libro bien estructurado, sección por sección, tema por tema.
    Y en general un buen libro como consulta o libro de texto.
