Welcome to the State Constitutions web site, a portal to the texts of the state constitutions of the United States. There have been almost 150 state constitutions, they have been amended roughly 12,000 times, and the text of the constitutions and their amendments comprises about 15,000 pages of text.

Earlier collections of constitutions by Poore, Thorpe, and Swindler are available in printed sources. Our texts have several advantages over these compilations:

1) They are much more complete and accurate. We have made strenuous efforts to get accurate original texts for each constitution and complete sets of amendments.

2) They provide coverage through 2000. With a few exceptions, constitutional amendments are taken up through 2000.

3) Amendments to constitutions are associated with the article and section of text they amend. Unlike the printed sources where amendments typically appear in a list at the end of the constitution, amendments in our texts appear immediately after the text they amend.

4) Constitutional texts can be reconstructed at any point in time, using the "as of" search method. The original constitutional and all amendments up to the date specified can be retrieved as a whole document.

5) Text can be accessed by article, section, or part of a constitution.

6) Texts can be searched by keyword. Searches can be conducted on the entire set of texts (not recommended), for individual states or for pieces of constitutions. The search engine returns links to individual articles and sections of constitutions.

7) The constitutional texts are entered into a database. Each piece of text is assigned a unique identifier: state, year of constitution, article number, sub-article number, section number, sub-section number, and part number. Amendments, in general, are associated with the piece of the constitution they amend. In some cases, amendments "float," that is they do not amend an existing part of the constitution nor do they create a new numbered part of the constitution. This web site is the interface with the database.

8) Copies of the text files inputted into the data base are now available directly.

We are close to finishing the project. We hope to have complete texts of all the constitutions (with the possible exception of Georgia) available on the web site sometime in 2006.

The web site design has changed. We are no longer posting the Thorpe constitutions, as they have been superseded by our texts.

It is supported by a series of National Science Foundation grant SBR-9709490 American State Constitutions: A historical Series. The Office of Academic and Computing Services at the University of Maryland, Marie Gates, Aaron Safford, Dirk Walter, and Adam Singh have designed and maintained the web site.

Trisha Posey, Heather Jacobsen, Doug Campbell, Chris Esh, Mike Peterson, John Allison, Erik Christiansen, Tom Castillo, Marcy Wilson, Kate Keane, Jim DeAngelis, Mark Levengood, and David Darlington have all provided excellent research assistance gathering and verify constitutional texts and amendments. Steve Snyder helped coordinate the original gathering of 19th century constitutions. Vickie Fletcher kept everything straight and was a rock over the last five years.
