On Nov. 15th of 2021, the American President Biden signed Infrastructure Investment and Employment Act in which more than one trillion dollars were allocated. On Oct. 26th of 2022, American Library Association issued a report Leverage Libraries to Achieve Digital Equity for All, in which the developing opportunities brought to libraries by the Act were analyzed, practices to improve digital equity in various libraries were introduced, and suggestions were put forward for library to take part in the realization of digital equity in the background of the Act. The inspiration we can get from the report is that in order to improve digital equity, our libraries can seek policy support; the associations can be the leaders to unite various libraries and to bridge the digital divide from the point of people's livelihood.
