Corrections and Clarifications
In the report "Surface order and stability of Langmuir-Blodgett films" by D. K. Schwartz et al. (24 July, p. 508), the last line in the first column of page 508 should have read, "The AFM is also able to image surfaces under liquids, allowing us to examine LB films at molecular resolution in both air and water for the first time." The first molecular resolution images of LB films under water were published by M. Eggar et al. [J. Struct. Biol. 103, (1990)].
