The concept of a summer reading list has evolved to include professional development and technical skills, allowing individuals to boost their knowledge and make themselves more marketable in the future. The New Relic summer reading list features a diverse range of books covering topics such as software development, business strategy, and self-improvement, including "Working Effectively With Legacy Code", "Good Strategy, Bad Strategy", and "Machine, Platform, Crowd". These books offer insights into topics like functional programming, microservices design, and the effects of automation on the economy. The list also includes some "traditional" light summer reading options, such as "Gödel, Escher, Bach: An Eternal Golden Braid" and "Stop Chasing Carrots: Healing Self-Help Deceptions With a Scientific Philosophy of Life". Individuals are encouraged to share their own book recommendations using the hashtag #RelicReadingList.
