Kendrick Lamar's album To Pimp a Butterfly is set to join the permanent archives at Harvard Library.
The rapper's third studio album, unveiled in 2015, debuted atop the Billboard 200 and received widespread acclaim from critics, who praised its musical scope and the social relevance of the lyrics.
Now, the Grammy Award-winner's record is to go down in history as one of 200 classic hip hop works to be catalogued and permanently stored within the Harvard Library system, which is the oldest library in the U.S. and the largest university library in the world.
The album's inclusion in the prestigious institution is part of project being undertaken by 9th Wonder, a hip hop producer, rapper and lecturer from North Carolina.
9th Wonder, real name Patrick Denard Douthit, is working on the archive as a fellow of Harvard's W.E.B. Dubois Institute, and has named the project These Are The Breaks, in honour of Kurtis Blow's classic 1980 song.
In addition to Lamar's album, the other albums 9th Wonder has selected to go into the library to date include Nas' classic record Illmatic, Lauryn Hill's The Miseducation of Lauryn Hill and A Tribe Called Quest's Low End Theory. As part of his research, 9th Wonder also tracks down each original sample that was used on every song.
"These are the first four we chose to start with to live forever in the Harvard Library...and to be forever placed in the canon...complete with liner notes and the vinyl that was used in the production of the album," he captioned a photo posted on his Instagram page of the first four albums to enter the archive.
9th Wonder plans to enter another 196 albums into the collection.
