Contemporary documents, such as Supreme Court opinions, are even easier to access. In addition to texts, databases of many sizes and descriptions may be searched over the internet. Some, like Dissertation Abstracts, allow you to find dissertations on specific topics. Others are the catalogs of libraries, such as the Library of Congress, Harvard, Yale, Oxford, Heidelberg University and my own Concordia Theological Seminary's library. The OCLC database allows a user to consult thirty million titles held by Eighteen Thousand libraries with a single command.
Some sites have text libraries for bibliographies and book reviews.
Many publishers have put their book catalogs online. Several discussion groups that interest scholars of Lutheranism exist. Another exists for Calvinism, Anglicanism, Eastern Orthodox Churches and so on. As I write this paper, few true hypertextual documents exist on the Internet. For the most part, World-Wide Web documents are full text tables of contents to documents in locations around the world.
