The Myers-Briggs Type Indicator (MBTI) is a personality typing system made up of 16 different personality types. Here's a curated reading list for ISFJ (The Defender).
"A Defender (ISFJ) is someone with the Introverted, Observant, Feeling, and Judging personality traits. These people tend to be warm and unassuming in their own steady way. They're efficient and responsible, giving careful attention to practical details in their daily lives." (credit : 16personalities.com)
