Online archives are digital collections of documents, images, and other materials that are stored on the internet. They allow users to access historical records, research papers, photographs, and more from anywhere in the world. These archives can be maintained by libraries, universities, or organizations, making it easier for people to find and study important information. Many online archives focus on specific subjects, such as historical events, cultural heritage, or scientific research. They often provide search tools and filters to help users locate specific items quickly. By digitizing materials, online archives preserve valuable information and make it accessible to a broader audience.
