Purpose Deeni Madaris of Pakistan and their libraries are playing an important role in educating the large fraction of society. They have always been engaged in the development of social and cultural values of the Pakistani society. This study aims to investigate the organization of information resources and their utilization at Deeni Madaris libraries in the central Punjab, Pakistan. Design/methodology/approach Quantitative research approach was adopted for this study. A questionnaire was developed on the bases of related literature and discussions with experts of librarianship as well as Islamic studies in Pakistan. The questionnaire was sent to 49 Deeni Madaris, of which five did not have libraries and four did not respond. Forty (81.6 per cent) Deeni Madaris responded and provided the relevant data about their libraries. The collected data were analyzed through SPSS 22. Mostly descriptive statistics were applied to calculate the frequencies, percentage, means and standard deviations. A two-tailed t-test was applied to check the impact of cataloguing and automation on the use of information resources. Findings It was found that majority of the respondents developed their own classification and cataloguing methods for the organization of information resources and did not have a proper retrieval system. Majority of the respondents were providing lending services to readers. Teachers and final-year students were the key users of the libraries. They mostly referred to books, theses and serials written in Urdu and Arabic language. The situation of library computerization was very weak; only 19 libraries had computers and 11 of them have partially automated the library activities. Library automation and catalogue put positive effects on the use of library resources. Originality/value The exploration of the literature showed that libraries of Madaris in Pakistan have always been a priority, but these libraries did not get a position in the library literature as they deserve. This study will fill this gap.
