Intermediary mechanisms are examined in terms of the two stage model, i.e. end\u2010user, intermediary, \u2018raw database\u2019, and different forms of user \u2014 system interaction are discussed. The evolution of the terminology of online searching aids is presented with special emphasis on the expert\/non\u2010expert division. Terms defined include gateways, front\u2010end systems, intermediary systems and post\u2010processing. The alternative configurations that such systems can have and the approaches to the design of the user interface are discussed. The review then analyses the functions of online searching aids, i.e. logon procedures, access to hosts, help features, search formulation, query reformulation, database selection, uploading, downloading and post\u2010processing. Costs are then briefly examined. The review concludes by looking at future trends following recent developments in computer science and elsewhere. Distributed expert based information systems (debis), the standard generalised mark\u2010up language (SGML), the client\u2010server model, object\u2010orientation and parallel processing are expected to influence, if they have not done so already, the design and implementation of future online searching aids.<\/jats:p>","DOI":"10.1108\/eb026861","type":"journal-article","created":{"date-parts":[[2008,1,19]],"date-time":"2008-01-19T07:39:02Z","timestamp":1200728342000},"page":"218-262","source":"Crossref","is-referenced-by-count":16,"title":["ONLINE SEARCHING AIDS: A REVIEW OF FRONT ENDS, GATEWAYS AND OTHER INTERFACES"],"prefix":"10.1108","volume":"46","author":[{"given":"EFTHIMIS N.","family":"EFTHIMIADIS","sequence":"first","affiliation":[]}],"member":"140","reference":[{"volume-title":"Online searching aids","year":"1989","author":"EFTHIMIADIS E.N.","key":"p_1"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1002\/asi.4630370407"},{"key":"p_3","first-page":"109","volume":"22","author":"BELKIN N.J.","year":"1987","journal-title":"Annual Review of Information Science and Technology"},{"volume-title":"Interaction in information systems: a review of research from document retrieval to knowledge-based systems","year":"1985","author":"BELKIN N.J.","key":"p_4"},{"volume-title":"Perspectives in information management.","year":"1989","author":"EFTHIMIADIS E.N.","key":"p_5"},{"issue":"3","key":"p_6","first-page":"155","volume":"2","author":"FENICHEL C.H.","year":"1985","journal-title":"Microcomputers for Information Management"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1108\/eb024201"},{"issue":"1","key":"p_8","first-page":"33","volume":"10","author":"LEVY L.R.","year":"1986","journal-title":"Online"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1108\/eb024244"},{"issue":"1","key":"p_10","first-page":"31","volume":"12","author":"HAWKINS D.T","year":"1988","journal-title":"Online"},{"key":"p_11","first-page":"6","author":"SPIGAI F.","year":"1984","journal-title":"Information Today"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1126\/science.3885395"},{"volume-title":"comps.
