The present structure of the Witt Computer Index data entry
system is described. The Witt Library of photographs and
reprodutions contains some 1.5 million seperate illustrations
covering paintings, drawings and engravings of Western Art. To
broaden search possibilities from only 'alphabetically by
artist' (as is its physical organization on the shelves) to
headings as subject, ownership, date, location, provenance, the
project to computerize the index started in 1984. A socalled
record-format is given. First estimates are: 10 minutes per
record, and with a staff of ten full-timers the completion of
the indexing process will take about 10 year.
