This research discusses the comparison of the utilization of printed theses and non-printed theses at the UPT Library of UIN Datokarama Palu as reference sources for students. The problem that will be examined in this research is How is the value of the utilization of printed theses and non-printed theses in the UIN Datokarama Palu repository as a reference source for UIN Datokarama Palu students? This research uses a quantitative descriptive approach with a comparative method. The research population is final semester students of UIN Datokarama Palu, with a sample size of 99 respondents selected using purposive sampling technique. The data collection methods used are observation and questionnaire. The data analysis conducted in this research is using the help of the Statistical Package for Social Science program, which is the software (SPSS) version 25, to carry out data analysis activities. The research results show that the average utilization level of non-print theses is 3.08, while print theses achieve an average of 2.99, both falling within the good category. Based on the results of the Paired Sample t-Test, a significance value of 0.062 was obtained with a calculated t-value of -1.886. This significance value is greater than the significance level of 0.05, and the calculated t-value is smaller than the table t-value, which means there is no significant difference between the utilization of print theses and non-print theses as student reference sources. This indicates that although non-print theses slightly outperform in some indicators, statistically their utilization level is still comparable to print theses. In other words, these two types of collections are still utilized relatively equally by students of UIN Datokarama Palu as reference sources to support academic activities.
