A COMPUTER BASED SEARCHABLE FILE OF JOURNAL REFERENCES IN THE FIELD OF PARTIAL DIFFERENTIAL EQUATIONS
George C. Francis · Defense Technical Information Center (DTIC) · 1970
A computer was programmed to prepare a searchable and updatable magnetic tape file of journal references in the field of partial differential equations. Multiple simultaneous queries involving Boolean logic are permitted and were used in automatic indexing of the file prior to publication of a first version. Search strategies are partially self-organizing. Examples of program use are included in the report.
