    Abstract
    A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

    Abstract
    Bibliographic control does not differ in substance from one type of material to another. Therefore it is not possible to separate the bibliographic control of music materials entirely from the larger domain of bibliographic control activity. The literature of music librarianship is examined for relevant theoretical explanations. Specific problems of description and access are used to show that, in general, the requirements for bibliographic control of music fit neatly into the theoretical structure for all bibliographic control. The primary purpose of descriptive cataloging of musical objects is to identify and differentiate among objects in a library collection. Where the concept of responsibility is relevant, access is provided through the names of composers or performers. Systematic access is provided through co-equal facets: medium, manifestation, and form.
