An Ocean of Doubt is the fourth installment in The Emo Diaries series of compilation albums, released September 28, 1999 by Deep Elm Records. As with all installments in the series, the label had an open submissions policy for bands to submit material for the compilation, and as a result the music does not all fit within the emo style. As with the rest of the series, An Ocean of Doubt features mostly unsigned bands contributing songs that were previously unreleased. Notably, it features the first song released by Further Seems Forever.
