The Science of Search: How Search Engines Work?

There are a vast number of ways that the library system has changed throughout the decades. There was a time when all of the classifications were on paper cards that you had to sort through by hand. Now, most library systems are digital, helping librarians and patrons find what they are looking for with a click of a mouse. As you consider getting a degree in library science, think about the various ways that libraries have progressed in the digital age. Not only can we use physical books to gain knowledge and perform research, but we now have a multitude of different search engines to scour the internet for e-books, peer-reviewed articles, magazines, and scholarly journals. With so much information at our fingertips, it can be a little overwhelming and confusing trying to find correct and relevant information. This is where a librarian comes into the picture. Librarians are very familiar with the various ways to properly and efficiently search for information. They can help library patrons find what they need without wasting time with the searching process.
