The project was overseen by the former Beatle's wife, Yoko Ono.
The John Lennon "Gimme Some Truth" campaign is to begin Oct. 4 in the United Kingdom and Oct. 5 in North America. Lennon was shot and killed in New York in 1980 at age 40. His birthday is Oct. 9.
The albums to be reissued are "John Lennon/Plastic Ono Band" (1970)"; "Imagine" (1971); "Some Time in New York City" (1972); "Mind Games" (1973); "Walls and Bridges" (1974); "Rock 'n' Roll" (1975); "Double Fantasy Stripped Down (2010)/Double Fantasy" (1980); and "Milk and Honey" (1984.)
The remastered albums and various collections featuring music from them will be available on CD and for download purchase from all major digital service providers, EMI said.
"In this very special year, which would have seen my husband and life partner John reach the age of 70, I hope that this remastering/reissue program will help bring his incredible music to a whole new audience," Ono said in a statement Tuesday. "By remastering 121 tracks spanning his solo career, I hope also that those who are already familiar with John's work will find renewed inspiration from his incredible gifts as a songwriter, musician and vocalist and from his power as a commentator on the human condition. His lyrics are as relevant today as they were when they were first written and I can think of no more appropriate title for this campaign than those simple yet direct words 'Gimme Some Truth.'"
