Online Searching of ERIC: Impact of Free Text or Controlled Vocabulary Searching on the Design of the ERIC Data Base.
The variety of searchable and printable formats of Educational Resources Information Center (ERIC) data base records has led to different searching methods, which have fostered the confusing state of affairs wherein different results are possible for the same search; this 5-part report describes an investigation of ERIC online use that studied the relationship between free text or controlled vocabulary searching and the design of the ERIC data base. Part I presents the experiences and practices of 45 ERIC searchers who use a number of different retrieval systems. Part II examines the use of free text searching vs. controlled vocabulary searching in over 600 search traces from 18 different ERIC online searchers using four different retrieval systems. Part III uses six search queries from the Online Training and Practice Manual for ERIC Data Base Searchers (ONTAP) to test controlled and free text vocabulary searching strategies. Part IV compares the format of items in the two ERIC printed services (RIE and CIJE) with their online versions in three retrieval systems, makes suggestions for improvements, and reviews previous retrieval effectiveness studies. Part V comprises an annotated bibliography listing 53 citations published from 1970-1978 that deal with online searching using free text or controlled vocabulary. Tables, illustrations, graphs, and figures are used throughout the report. (Author/JD)
