Historical archives are useful tools when doing research, specifically research that could benefit using multiple sources. The sources provided in the syllabus are examples of informational archives. They provide a large amount of information that is accessible and searchable in one area. Archives are beneficial to historians because they can access any type of document, letter, biography, essay, that was uploaded to the archive just by searching for specific terms. For example, the Darwin Correspondence Project Archive gives the ability to search all items on the archive that has something to do with Charles Darwin, or that he produced. This helps when doing large amounts of research because it can gather you lots of information with minimal searching effort. Limitations met by archives is that it can only search items that were accepted into the archive which could pose bias on the organizer or suppliers part.
