請問 美國國會圖書館 一開始是專門圖書館 後來才轉型為國家圖書館 是這樣嗎?

你好！

有關美國國會圖書館的發展歷史，請參見：

1. The Library of Congress >> About the Library >> History

「The Library of Congress was established by an act of Congress in 1800 when President John Adams signed a bill providing for the transfer of the seat of government from Philadelphia to the new capital city of Washington. The legislation described a reference library for Congress only， containing "such books as may be necessary for the use of Congress - and for putting up a suitable apartment for containing them therein…"」

2. Jefferson's Legacy: A Brief History of the Library of Congress

「The Library of Congress occupies a unique place in American civilization. Established as a legislative library in 1800， it grew into a national institution in the nineteenth century. ...

「Since its creation， the Library of Congress has been part of the legislative branch of the American government， and even though it is recognized as the de facto national library of the United States， it does not have that official designation. Nevertheless， it performs the functions performed by national libraries elsewhere and has become a symbol of American democracy and faith in the power of learning.」
