Where is the life we have lost in living?
Where is the wisdom we have lost in knowledge?
Where is the knowledge we have lost in information?
T. S. Eliot, 1934, The Rock
Indexing the geoscience literature in one language presents varying problems, such as the compaction of ideas in single words or phrases. Exchanging such indexing information with other computerized databases operating in other languages presents a whole set of problems, including linguistic, cultural, scientific, computer, and historical problems. The exchange of bibliographic information between the GeoRef database and the PASCAL-GEODE database, starting in 1981, provided an opportunity to tackle these problems. To achieve concordance, the two databases had to modify their respective thesauri and indexing philosophy in order to maximize the use of computers in the exchange process. The exchange is now operational.
