- Abstract
- The progress in the first century of the classification era is traced in the three majot perios: pre-facet, transition-to-facet, and facet period. The facet-period is divided into the restricted facet formula, generilised facet formula periods and the two relativity periods - viz. Dorking and Elsinore periods. For each of the six resulting periods, the chief achievements in library classification and the social factors leading to them are mentioned. The achievements of the Dorking period just ending are described in greater detail. The follows the programme of research work for the Elsinore period of 1965 to 1975. A programme for fundamental research in the idea, verbal, and notational planes is chalked out. Then follows the programme for routine research in the building of schedules of common isolates, whcih is a back log from the Dorking period, and in the new area of the design and building of schedules for the depth classification of diverse subjects, needed for documentation work and service. Lastly, the organization suitable to carry out the programme is outlined
