Google Base is a place where you can add all types of information that we'll host and make searchable online.
You can describe any item you post with attributes, which will help people find it when they search Google Base. In fact, based on the relevance of your items, they may also be included in the main Google search index and other Google products like Froogle and Google Local.
From the FAQ's on the site, it is not immediately clear who would own the data; presumably it would be the person posting, but that is not clear. Does this create opportunities for legal researchers wanting to post and share law-related information?
