Most courts have a list of newly-filed bankruptcies available on the Web.
However, these courts often don't provide access to anything but a list of newly-filed cases. Theses sites also don't provide any type of search capabilities, nor do they have docket information, etc. Often, the best resource to access such information is any one of a number of subscription-based services. So, if you're using one of these sources, you're adding a layer in between you and the information you're seeking. In addition, Lexis and Westlaw can be prohibitively expensive.
