The rest of the sites are, in a word, pitiful. Of course, we are still in the embryonic stage of the Internet, and everyone is still getting their feet wet. I'm certain that within the next ten to fifteen years an individual will be able to perform a search of the Wise County District Clerk's files at home via the Internet. The information available will probably include not only what cases have been filed but what documents have been filed in the case as well. Heck, a state wide search to determine, for example, if a potential employee has every been a party to a lawsuit, civil or criminal, anywhere in Texas is not out of the question.
Privacy issues are, of course, a concern.
If you have ever had your name on a document in the district clerk's office you probably haven't been worried to much about disclosure. The reason is that someone must physically walk to the courthouse, ask for the file, and then turn to the page in the file which contains your name in order to be discovered. This, of course, is not likely to happen. At least, no one is going to do that for fun. Public information, practically speaking, has not meant public dissemination.
