The paper has also taken an initiative to formulate an exact matching technique between user's subject interest and document profile with exploration along with electronic delivery of voluminous information technique. Suseela Kumar defines SDI as the practice in some libraries such as special libraries whose users are small in number to maintain reader profiles which indicate the subjects of interest to them; advanced or elementary level in which they are and the form in which information is required. However, it can be defined in a comprehensive sense that, SDI is a type of current awareness service which under optimum conditions involves screening of documents, selecting information exactly tailored to meet the specific research needs of each user or a group of users and supplying the information directly to each individual or group so that user can keep abreast of the latest developments in the area of his specialization [5]. ONLINE PROCEDURES OF SDI SERVICE SDI is a current awareness mechanism through which the individual information user can expect to receive regular notification of new literature and data in accordance with his/her statement of interest or profile. Note: In case the user's query is not confined to certain range of time in which ‘the document published’ and when no specific medium of language of information is required, then ultimate matching function is performed directly over the latest search result and document profile is prepared.
