Public libraries, a safe haven and valuable resource for students and families, have not been immune to the severe effects of the COVID-19 pandemic. Following the onset of the pandemic in March 2020, libraries throughout the Philippines shut down in-person operations. These shutdowns negatively impacted students and families reliant on libraries as places to study, access internet, and socialize. Following the temporary suspension of in-person operations, public library staff responded to challenges faced by students and families unable to access library resources. The general purpose of this study is to assess the usage patterns of library clienteles in selected public libraries in the National Capital Region (NCR) that lead to the impact of innovation and technology in the public library use and development. Specifically, it seeks to answer the following questions: 1) What is the profile of the respondents in terms of: age, gender, and educational attainment?; 2) What is the level of awareness of the respondents in the public library’s online resources?; 3) What is the stand of the respondents in the shift toward online resources?; and 4) What were the challenges that the respondents face in light of this shift and transition in innovation and technology? The descriptive survey method using a questionnaire was used in the study to obtain information concerning usage patterns of library clienteles in selected public libraries. The data gathered from the survey questionnaires were tabulated and analyzed to ascertain the adequacies of each problem. Descriptive statistics refers to a branch of statistics that involves summarizing, organizing, and presenting data meaningfully and concisely. On the basis of the findings, the conclusions were drawn. New technology brings learning curves, adjustment periods, and inevitable technical difficulties. Furthermore, most of the respondents had positive feelings about their public libraries. Those who have used a library’s app or website feel generally positive about the online resources available to them. The researcher recommends the following measures: 1) Public libraries must provide accessible online resources such as e-books and e-journals; 2) Technology training and trainings on how to using internet to do things like downloading an application, how to participate in online classes, video call, and Zoom meeting, or use a search engine like Google must be introduced by the public libraries and librarians to their respective library clienteles; 3) LGUs in the National Capital Region must provide their public libraries necessary funds for online resources and Wi-Fi connectivity; 4) The Head Librarian of public libraries may tap the help of private sectors in providing them the latest innovations and technologies in public libraries; and 5) Support the proposed bill of Senator Angara on modern and electronic means of delivering library services and resources to users.
