The sole objective of this document is to make available the researchers, programme workers, administrators, students, medical facility and other readers, the scientific research conducted by National Tuberculosis Institute (NTI), as they may not have an easy access to the research papers specially those brought out during the early sixties and seventies. The summaries of all the studies carried out at NTI since its inception have been updated. Besides, many conceptual, review and evaluation papers, have also been included keeping in view their importance.

Tuberculosis, for ages, has been regarded as a multifactorial, multidisciplinary disease. The TB patient, his relationship with his family and community, the perception of the disease by him and his associates, have an influence on his behaviour and outcome of treatment. Whereas, research on the epidemiology and drug regimens give us information on the extent of the disease and what drugs in what doses are effective, it fails to tell us about the social aspects of the disease, the behaviour of patient before and after diagnosis and the intricate relationship among the patient, community and the health system. The concept of research directed at the interplay of these factors, called operational research, was conceived by NTI and it was one of the foremost institutions to study this in detail. The approach of operational research facilitated us to realize the ideal from the practical so that undue expectations are not fixed only to be disillusioned and criticized later. These ground realities have been sub grouped as 'Problem Definition (OA), 'Programme Development' (OB) and 'Programme Formulation (OC). The papers on 'Awareness of symptoms by TB patient' 'Action taking pattern of symptomatics', 'Potential of Case-finding under the programme', and 'Operational efficacy of drug regimens' enlighten the reader on the rationale of the methodologies adopted in the programme and also on what best to expect and achieve. The papers exclusively grouped under Bacteriology, BCG, X-ray etc. highlight the contributions directly related to the subject. Miscellany includes papers on Health economics, Health Education, Dissemination of Information, and other Projects. Each summary consists of : Introduction, Objective, Design, Methodology, Results and Conclusion accompanied by Key Words. This will enable the user to get the required information without referring to the original paper.

The summaries are arranged topic wise and subsequently chronologically, accompanied by key words that will help the user to trace the particular one required. They have been re-grouped as Epidemiology, Bacteriology, Sociology, BCG, X-ray, Operations Research and Miscellany for better comprehension.

Subject index is derived by using the key words assigned to each summary, and author index includes all authors & corporate body & both the indexes give reference to Sl. No. (ie. record number) allotted to each publication / record. The indexing technique used in the document will facilitate to retrieve specific records related to a particular topic either by referring to subject or author indexes. Of the total 375 publications, approximately 200 have been included in the document and contains the multidimensional research done in the field of tuberculosis.
