Accessibility of library search tools is measured not only by their adherence to accessibility guidelines, but also by the ease they offer users to find accessible resources. This makes library metadata an object of study in library accessibility. Past studies encouraged exploring the application of metadata in fostering accessibility. The studies also recommend considering user requirements. This study aimed to examine the role of metadata in making the process of resource discovery and access accessible to people with low vision impairments. Based on recommendations of past studies, a simple prototype was developed to test the idea of allowing users to set their own metadata preferences on their search interfaces. Participants were recruited to explore the prototype. The initial findings showed that adding such option in preference settings may be more appealing to frequent users than "one-time" users. However, the participants were able to provide comments on what to improve for the next iteration.
