Structure of an Inf-Doc-System and its realization as an Experimental System in APL plus
H. Steinhauer · 1975
There was a time when our team in the STIFTUNG REHABILITATION Heidelberg expanded suddenly and so did the literature which we needed for our work. To prevent the chaos to be expected I wrote an APL Plus program which was intended to bring some structure in our library. This program was named EXIS, i.e. Experimental Information System.
