    The core of OMC-1 has been imaged with the Near-Infrared Camera and Multiobject Spectrometer (NICMOS) on board the Hubble Space Telescope at 0 2 resolution in 1% filters at 2.12 and 2.15 μm, revealing intricate structures in both continuum and shocked molecular hydrogen line emission. Numerous H -emitting clumps surrounding the BN/KL region have been resolved for the first time, several of which exhibit prototypical bow-shock morphologies with -shaped tips. We interpret these to be lower excitation analogs of similar structures 2 northwest of the core observed with ground-based telescopes. Many of the elongated H structures and bow-shock features appear to radiate outward from a region within a few arcseconds of radio source I, which suggests that the H energetics are dominated by one or more outflow sources in this region. However, the orientations of some features are unrelated to this apparent outflow pattern. The deeply embedded, suspected outflow source I remains undetected at 2 μm, although two faint new continuum sources have been detected within 1 of it. The newly resolved H features with bow-shock morphologies are located in regions previously identified as bow shocks by highly blueshifted components in their line profiles. In contrast, regions of H emission that are diffuse in the NICMOS image have broad, smooth line profiles. Several continuum features have an arclike appearance, which suggests interactions of winds with the ambient medium. At least 40 stellar or protostellar continuum sources have been detected, including at least one proplyd and four pairs of binary stars.

    This essay is based on the seventeenth annual D. F. McKenzie lecture given at the University of Oxford on 2 March 2011. McKenzie is best known for his tolerant unrolling of the bibliographical into wider cultural and social realms, together with his implication that the material book can be treated as an index of them. Eggert’s essay argues for a timely counterbalance: the need for a regathering of the concept of the work, which largely fell from view during the period of high literary theory. A new model for interpretation is proposed by building reading, and thus the aesthetic, into the definition of the work, while retaining the evidentiary witness of the material book. The model offers, in other words, a justification for folding book history and bibliography into the literary study of all works that have enjoyed an extended history of printing and reprinting.

    Journal Article
    The relations between James Brooke and the various peoples of northwest Borneo have attracted considerable scholarly attention. Nineteenth-century Iban experiences have been analysed extensively and continue to provide the basis for a healthy industry in historical anthropology. Daniel Chew and Craig Lockard examined the development of the Sarawak Chinese community. Sabihah Osman explored Malay political activity during the Brooke period. In contrast, although Bidayuh were the subject of a detailed anthropological survey in the 1950s, political relations between Bidayuh and Rajah Brooke's regime have been largely ignored by scholars.
