Campbell, Matthew, Rhythm and Will in Victorian Poetry, Cambridge University Press, 1999.

Campbell devotes an entire chapter to In Memoriam,
putting its structure into context with the works of
Tennyson's contemporaries.

Kingsley, C., "On In Memoriam (1850) and Earlier Works," in Tennyson: The Critical Heritage, edited by John D. Jump, Barnes & Noble, 1967, pp. 172-85.

time period when it was published gives a sense of
what a departure the poem was from Tennyson's
usual style and how uncertain Tennyson's reputation
was before In Memoriam sealed his fame.

This book-length bibliography is several decades old,
but it is useful as a reference to many studies of the
poet published in the nineteenth and early twentieth
centuries.
