Discussion
Which of the following information products are based on review type of library services ?
(i) Current Awareness Service
(ii) Trend Reports
(iii) Newspaper Clippings
(iv) State of the Art Report
Codes :
Answer: D
The review-type products are (ii) Trend Reports and (iv) State of the Art Report.
Review-type information services digest and evaluate the literature of a subject. A trend report surveys developments in a field over a period, and a state-of-the-art report sums up the current level of knowledge or technology on a topic. Both synthesise many primary documents into an evaluated account.
Current awareness services and newspaper clippings are alerting services: they announce or reproduce new items quickly without reviewing or evaluating them, so codes including (i) or (iii) are wrong.
