The Mindset of Dependability

Computer software is legendary for its production time and cost overruns, and for its fragility after it is written.

Making a digital library: the chemistry online retrieval experiment

The CORE project is an electronic library of primary journal articles in chemistry, containing about five years of twenty primary journals published by the American Chemical Society (about 425,000 pages).

Each page was scanned and segmented, with graphical units isolated and linked to figure references in the articles. The original machine-readable typography was converted to SGML format and the results were used to build databases with indexes for full-text Boolean searching; a single search engine served data for each of three X-Window interfaces.
