The Rossetti MS. is the name used in this edition as a descriptive title for Blake's book of notes and sketches, commonly called 'The MS. Book,' and sometimes, less correctly, 'Ideas of Good and Evil.' The latter title, partially covered by a pencil sketch, is found written, in bold script characters, on the verso of the second leaf. In all probability Blake intended it to refer to the series of designs, beginning on p. 15, afterwards engraved and published as The Gates of Paradise. The poems which some editors include under this title had not then been written.
The Rossetti MS. is a foolscap quarto volume (73⁄4x63⁄8 inches) of 58 leaves, paginated consecutively 1-116 by its present owner.

Rossetti transcribed certain of the contents, heading them 'Verse and Prose by William Blake (Natus 1757: obiit 1827). All that is of any value in the foregoing
