Book Description
A wise and hilarious novel about love, heartbreak, and rock and roll from the bestselling author of About a Boy and Dickens and Prince Now a Hulu series starring Zoë Kravitz!

Rob seeks refuge in the company of the offbeat clerks at his store, who endlessly review their top five films; top five Elvis Costello songs; top five episodes of Cheers. Rob tries dating a singer, but maybe it's just that he's always wanted to sleep with someone who has a record contract. Then he sees Laura again. And Rob begins to think that life with kids, marriage, barbecues, and soft rock CDs might not be so bad.

Book Description
A Hudson Booksellers Best Non-Fiction Book of the Year, with foreword by Wilco's Jeff Tweedy High Fidelity meets Killing Yourself to Live when one man searches for his lost record collection. As he finds himself within spitting distance of middle-age, journalist Eric Spitznagel feels acutely the loss of… something. Freedom? Maybe. Coolness? Could be. The records he sold in a financial pinch? Definitely. To find out for sure, he sets out on a quest to find the original vinyl artifacts from his past. Not just copies. The exact same records: The Bon Jovi record with his first girlfriend's phone number scrawled on the front sleeve. The KISS Alive II he once shared with his little brother. The Replacements Let It Be he’s pretty sure, 20 years later, would still smell like weed. As he embarks on his hero's journey, he reminisces about the actual records, the music, and the people he listened to it with—old girlfriends, his high school pals, and, most poignantly, his father and his young son. He explores the magic of music and memory as he interweaves his adventures in record-culture with questions about our connection to our past, the possibility of ever recapturing it, and whether we would want to if we could. "Memories are far more indelible when married to the physical world, and Spitznagel proves the point in this vivid book. We love vinyl records because they combine the tactile, the visual, the seeable effects of age and care and carelessness. When he searches for the records he lost and sold, Spitznagel is trying to return to a tangible past, and he details that process with great sensitivity and impact."—Dave Eggers, New York Times bestselling author of The Circle

Book Description
UX design has traditionally been deliverables-based. Wireframes, site maps, flow diagrams, content inventories, taxonomies, mockups helped define the practice in its infancy.Over time, however, this deliverables-heavy process has put UX designers in the deliverables business. Many are now measured and compensated for the depth and breadth of their deliverables instead of the quality and success of the experiences they design. Designers have become documentation subject matter experts, known for the quality of the documents they create instead of the end-state experiences being designed and developed.So what's to be done? This practical book provides a roadmap and set of practices and principles that will help you keep your focus on the the experience back, rather than the deliverables. Get a tactical understanding of how to successfully integrate Lean and UX/Design; Find new material on business modeling and outcomes to help teams work more strategically; Delve into the new chapter on experiment design and Take advantage of updated examples and case studies.
