The intro on this site says:
Beginning with the Continental Congress in 1774, America's national legislative bodies have kept records of their proceedings. The records of the Continental Congress, the Constitutional Convention, and the United States Congress make up a rich documentary history of the construction of the nation and the development of the federal government and its role in the national life. These documents record American history in the words of those who built our government.
Books on the law formed a major part of the holdings of the Library of Congress from its beginning. In 1832, Congress established the Law Library of Congress as a separate department of the Library. It houses one of the most complete collections of U.S. Congressional documents in their original format. In order to make these records more easily accessible to students, scholars, and interested citizens, A Century of Lawmaking for a New Nation brings together online the records and acts of Congress from the Continental Congress and Constitutional Convention through the 43rd Congress, including the first three volumes of the Congressional Record, 1873-75.
[SIZE=-1]The mission of the Library of Congress is to make its resources available and useful to Congress and the American people and to sustain and preserve a universal collection of knowledge and creativity for future generations. The goal of the Library's National Digital Library Program is to offer broad public access to a wide range of historical and cultural documents as a contribution to education and lifelong learning. [/SIZE][SIZE=-1]The Library of Congress presents these documents as part of the record of the past. These primary historical documents reflect the attitudes, perspectives, and beliefs of different times. The Library of Congress does not endorse the views expressed in these collections, which may contain materials offensive to some readers. [/SIZE]
It doesn't say that every document is an enforceable law. In the case of the DOI, it doesn't even attempt to make any laws. It says that we're breaking away from Britain and these are the reasons why.
Even if it did make law, it wouldn't settle the abortion issue. Yes, it says that people have a right to life, but the abortion dispute is over when an entity gains personhood, and thus gains that right,and the DOI doesn't mention that. The court said that a fetus doesn't have the right to life until the third trimester. You can yell all you want that the DOI says people have the right to life, and Roe v. Wade will just respond "not until the third trimester".
You might think they're wrong. You might be right. But the issue you're arguing over is the timing of the embryo's personhood. You're not arguing over whether people have a right to life (you an the court both say "yes" to this), and you're not arguing over whether privacy is more important than life (you and the court both say "no" to this).
