    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
    Australian libraries have kept up with the latest technology and innovation in cataloging. The Australian Bibliographic Network is a shared cataloging-based national bibliographic utility. This essay delves into the relationships of the ABN, the Australian National Bibliography, AUSMARC, and the role of the Australian National Library in the creation of these elements of computerized cataloging in that country. It also discusses some of the policies and procedures utilized by Australian libraries in their automated cataloging environment, as well as looking at some of the environmental attitudes arising from the change to automated cataloging. Finally, the essay concludes with an outline of some of the similarities and differences between the AUSMARC and USMARC formats.

    Abstract
    Early in 1988 the East German Akademie der Wissenschaften set up in the Centre for Scientific Equipment the local computer network ELAN. This offers data base access, including to data of other network members, and an electronic mail system. Users of the network include directors and workers in research and deelopment projects, and in technological production, business and safety processes. The role played by the network in the provision of information to educational institutions is central. The network is being perfected in conjunction with standardisation and coordination of information technology equipment in other activities of the center. Consistent use of technical processes has led to rationalisation of work. Resistance among users to the new facility must be overcome, for example by adding their research papers to the data base.
