Pound foregrounded the importance of "shaping" poetic books through particular arrangements of individual poems by using his ideogrammic method as the crucial organizational principle for constructing Personae (1926). Critics have long understood Pound's use of the ideogrammic method in individual poems, but have so far ignored his application of it to the structuring of poetic books and sequences. Lea Baechler and A. Walton Litz, the editors of a 1990 edition of Personae (1926), however, have moved a crucial section of poems, and their rearrangement of the original text both disregards evidence of authorial intention and obscures Pound's innovative principles for arranging his shorter poems into meaningful sequences.
