The organizational climate is the organization's personality and employees' perceptions of its environment. The study aimed to determine the relationship between organizational climate and staff attitude in Iranian medical university libraries.

In this cross-sectional study, all librarians of three Iranian medical libraries were included. Data was collected using the ClimateQUAL questionnaire. Specialists confirmed its validity and reliability, and Cronbach's alpha obtained 0.953. The collected data was analyzed in terms of descriptive and inferential statistics (p-value<0.05) in SPSS software version 22.

The overall mean of the organizational climate for the studied medical libraries was 111.87±49.00. There were no significant differences between these libraries based on the organizational climate (p=0.711). Regarding staff attitudes, the lowest and highest total mean were for job satisfaction and work unit conflict, respectively. There was a significant relationship between the organizational climate and staff attitudes (r=0.352).

The reinforcement of demographic diversity, customer service, teamwork, and continual learning in medical libraries can be more effective in improving the organizational climate of these libraries. The positive organizational climate has a positive effect on staff attitudes, job satisfaction, and continuing to work with the library.
