This text is sort of a 1 dimensional sister to Baby Rudin. Abbott leaves many proofs to the reader, so using this book for studying the material outside of class can be bothersome in my opinion. I am a grad student in math and can do the proofs requested, but it would be nice if he actually gave them on occasion. He also at times sort of side steps larger aspects of analysis such as topological compactness. I would view this text as a sort of starter copy to Rudin. A bit more modern, with some good explanations, but a wee sparse in its examination of some proofs.
