Collaborative Online Topical Bible
Openbible.info has released a searchable topical Bible that gets better (we hope) the more it is used. There are other topical Bibles online, but this one is dynamically updated and has the ability to improve results through user votes.
The topical Bible combines the Yahoo! and ESV Bible web services to identify topics and find relevant verses. It currently has about 4,000 topics. Searching for a topic that doesn’t exist will automatically add it to the topical Bible, which will then scour the Internet for relevant verses.
You can vote on whether the listed verses are relevant to the topic—or you can suggest new verses. Over time, the topical Bible should become better at identifying what people think the Bible says about a topic.
