I just found out that the first Library of Congress was actually burned down by the British in the early 1800s. All of the books were lost in the fire.
We were left without a Library when Thomas Jefferson decided to donate his huge collection to start a new Library of Congress. They say that the reason the Library of Congress today has books on so many different subjects and areas is thanks to Thomas Jefferson. The first library just had books relating to America and government. But Thomas Jefferson's collection had all kinds of books, even on science and philosophy. The Library now is still following his collection and example and now has more than one hundred million resources.
I admire President Thomas Jefferson even more now that I know how he has contributed to the Library of Congress.
