- 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

- Describes the various steps taken to produce a major bibliographic catalogue on CD-ROM: Describes the history of the development of the printed catalogue, its conversion to machine-readable form and the subsequent design and production of the CD-ROM version. The functional requirements of the software are discussed as are making plans and pricing decisions. Some features of the product, the British Library General Catalogue of Printed Books to 1975, are illustrated.

- Abstract
- Outlines previous work done in the field of compatibility between indexing langugaes (IL), and describes the scope, limitations and advantages of establishing compatibility between IL. Suggests methods for verbal comparisons between IL as well as generation of an alphabetical comparison matrix M1. Conceptual comparisons, however, demand a conceptual reorganization of M1 into a compatibiliy matrix M2 with its two alternatices, namely a system-related matrix M3 and a hierarchical matrix M4. In conclusion, the use of a compatibility matrix and organizational problems are described
