This research delved into the familiarity and use of the OPAC by scientists affiliated with DRDO laboratories in India. A survey was administered to 885 Scientists (B, C & D) across different DRDO libraries in the country. Out of the distributed questionnaires, 720 were collected and utilized in the analysis. The results showed that 78.75% of the respondents were acquainted with OPAC services. The paper explores several facets of OPAC, including awareness levels, utilization for searching documents in Technical Information Centers (TICs), frequency and purpose of use, as well as reasons for lack of familiarity with OPAC.
