COMPARISON OF HDL SDI SERVICES BASED ON A PRELIMINARY IEEE TAPE AND ON DDC TAPES,
Abstract
The results of the HDL SDI service measured in numbers of items requested by its subscribers are presented and analyzed for each of two types of bulletins: one derived from the DDC tapes on reports literature, and one based on a preliminary IEEE tape containing open (periodical) literature. The latter contains the information of only one-half the August 1970 issues.
