When planning to learn real analysis, several textbooks are recommended. "Baby Rudin" is frequently mentioned, with mixed reviews; while some find it concise and suitable for professional analysts, others consider it challenging and less accessible for beginners. Michael C. Reed's text is noted as a decent option, and Riesz and Nagy are also mentioned positively. For those interested in a deeper exploration of metric spaces and functional analysis, Dieudonné's "Foundations of Modern Analysis" is suggested, although it does not cover measure theory. The discussion highlights the varying interpretations of real analysis, with some focusing on measure and integration, while others consider limits and metric spaces.
