Many years ago, long before the Internet and artificial intelligence became a part of our lives, American engineer Vannevar Bush was looking for ways to solve a problem. He realized how difficult it had become for researchers to conduct their research and saw an opportunity to improve the process.
This was back in the 1940s, when anyone looking for articles, books, or other scholarly material had to visit a library and look for them using indexes. This meant sifting through entire drawers full of index cards, often sorted by author, title, or subject.
Once you found the material you needed, the process of making copies or extracts was tedious and time-consuming. You had to be very organized to keep your own records. And those who worked in several fields had it especially hard. Since each book could only be in one place, they had to be classified by one main topic only. So an article on cave art couldn't be in both the Art and Archaeology sections, and researchers often had to waste time searching for the right material.
