Web crawlers play a key role in scientific research by gathering information from the public web and indexing it for search engines. Before their existence, the scientific world lacked efficient communication between researchers, resulting in slower progress and disconnected pockets of information. Now, over 35% of research papers involve international collaboration thanks to over 11 million digitized papers available via search. Custom web crawling allows researchers to simultaneously search thousands of databases for critical information, fueling networked science.
