Below is a list of books I highly recommend to anyone interested in user experience and design
1. The Design of Everyday Things, by Don Norman
The philosophy of UX. I'd recommend this book to everyone regardless of the industry they're in, as it's written in plain, everyday language.
2. Design Is a Job, by Mike Monteiro
The UX designer's soft skills. Highly recommended to everyone who is either a UX person or working with a UX person, it's very enjoyable to read.
3. Don't Make Me Think, by Steve Krug
This is one of the must read books about usability and the art of simplifying.
4. About Face: The Essentials Of Interaction Design, by Alan Cooper
A great book for an overview of interface types and how to effectively design
5. Lean UX: Applying Lean Principles to Improve User Experience, by Jeff Gothelf
This is about UX in Agile and remote teams. Very good for everyone who is working with a geographically dispersed team and / or in an Agile environment.
This is a comprehensive encyclopaedia for everything regarding human computer interaction. Not to be read back to back, but highly recommended as a reference guide.
