DeHaven’s Book- 
Back in 2007, DeHaven was ready to air out all the personal details of Jay-Z’s life: that he wasnt a gangster, he wasnt a big time drug dealer and that he had less money than he said he did. Before Jay-Z was famous, Jay-Z worked for De-Haven selling drugs in New Jersey in the late 80s and early 90s. DeHaven was the boss and Jay-Z was one of his runners. DeHaven ended up getting arrested and spending a long time behind bars. In that time, Jay-Z became one of the most famous rappers of all time. The plan was for Jay-Z to help to DeHaven when he got out of jail. When DeHaven did get out of jail, Jay-Z did none of that. In fact Jay-Z was ignoring DeHaven altogether. DeHaven was pissed off and decided to release a tell all book about him and Jay-Z’s life. The book was completed and was supposed to be accompanied by a DVD, but the book never got released. Did Jay-Z stop the book from being released?
Funkmaster Flex’s Biggie Books- 
Funkmaster Flex in 2014 was originally working on a book about rare stories of hanging out with Biggie from the accounts of his family and close friends. When that book didn’t happen, Flex was working on a separate Biggie book that focuses strictly on his murder. Flex has still not released either one of his books. We spoke to the co-author and the murder book is still in the works.
Jay-Z’s Black Book- 
You might have forgotten about this one, but Jay-Z was releasing an autobiography with writer Dream Hampton back in 2003. Jay-Z did release a memoir back in 2012, but that was more memories about his life. This book was a full autobiography. The plan for the book was to be released shortly after The Black Album was released. In fact, in the Black Album CD booklet (remember those?) is a small excerpt from that book. It happens to be the only excerpt from the book ever released. Once the book was progressing along, Jay-Z didn’t like how many personal details of his life would be published and ultimately pulled out from releasing the book.
E-40’s Book Of Slang Dictionary- 
Back in 2003, E-40 announced that he was publishing a slang dictionary of slang he created in conjunction with Murder Dog Magazine. That book never materialized, and a decade later in 2014, 40 said that was going to be releasing his book of slang in the form of a app. E-40 never released that app either. E-40 should still release it because there still is a demand for it.
It Ain’t Hard To Tell by Nas- 
Back in 2012 Nas signed a book deal for his autobiography titled “Ain’t Hard To Tell”. The book’s focus was going to be on his relationships with Carmen and Kelis and his entire recollection the Jay-Z beef. In addition to all that, Nas was going to include “song deconstruction” where he explains some of his old lyrics verse by verse.
