As the gender gap in the STEM field is getting more and more attention,guiding girls'interest and participation has become a new concern in recent years,but the library field has not responded adequately.Gen-der-responsive practice principles,women-or girl-centered approaches,and action strategies to increase girls'participation in STEM can provide theoretical references for girls-focused STEM programs in the library field.Three types of practice as led by libraries,led by STEM relevant institutions and led by gender equality-related organizations can be practically referring to.On this basis,the paper puts forward some suggestions:inspire the key role of librarians,take advantages of the library service system and practice to enhance social cooperation,and carry out services for family engagement to improve out-library extension of resources and services.72 refs.
