In a number of readings, I came across selective dissemination of information (SDI). Though the term is somewhat dated, it can be manual or electronic. Selective Dissemination of Information (SDI) was a concept introduced by H.T. Luhn in 1958. His paper described an automatic method in providing currency in library service to scientists.. This feature allows revising a subscriber’s references as a database is updated. What can be accomplished via a user profile with SDI is : email notices of a current journal’s table of contents with links to full-text; access to a web-based received journal list with links to a table of contents of issues and full-text; and custom email notices of newly received books.
