Open Book is the tenth and final track on the worldwide re-issue of Jevetta Steele's first solo album Here It Is (Jevetta Steele is also part of the group The Steeles). The song was written by Martika, Levi Seacer, Jr. and Prince, and was produced by Prince under the pseudonym Paisley Park.
Although specific recording dates are unknown, initial tracking took place in December, 1990 - early 1991 at Paisley Park Studios, Chanhassen, MN, USA (during the same set of sessions that produced Love... Thy Will Be Done, Spirit, Don't Say U Love Me and Martika's Kitchen). Open Book was intended for the Martika's Kitchen album (where the other four songs recorded during the sessions were released), and was written as a response to Martika's song Safe In The Arms Of Love, which also appears on the album. Open Book quotes passages from this song - it is likely that Martika's writing input in the song is limited to those passages. It is not known when Jevetta Steele overdubbed her vocals.
