The present study aimed to scrutinize the EFL students' perspectives on library in various modalities to mediate EFL learning and to know the correlation of the EFL students' attitudes to the EFL students' academic achievement. Hence, quantitative research with descriptive and correlational research designs were applied. 112 EFL students in an English Education Department (EED) at a public university in West Nusa Tenggara, Indonesia contributed their responses by filling out an online questionnaire containing questions to answer the research goals and sharing their GPA files. To analyze the data, descriptive and correlational statistical calculations through SPSS 24 version were done. The results showed that EFL students had positive perspectives toward library modalities which were reflected by their attitude to frequently visiting the library in various modalities. Moreover, the EFL students’ positive belief about the correlation of their attitude with academic achievement was supported by statistical calculations and previous studies. However, further studies to confirm these research findings will be suggestible due to the limitations of this research. Hence, it is suggested to enhance the significance of the library in various modalities for academic purposes by increasing the visits.
