Routing of periodical is a "current awarness service" or" selective disimination of information".

Dear Mr. Babu,

 

                   As far as my understanding of the concepts in your question goes, SDI and routing of periodicals both are  types of current awareness service . The defference being, the SDI is highly personal service keeping in mind the preofile of the user ( i.e the interest areas of an individual user).

 

               In my opinion, If you are routing all the periodicals being subscribed by the library to all the users or a select group of users irrespective of their specialisation, areas of interest (i.e. the users' profile) in a fixed sequence, it is a kind of Current awarenes service.

                  The moment you start maintaining a users' profile and start routing periodicals according to their profiles, it becomes SDI.

 

Following link to the article on literature review of SDI will give you more insight into the topic
