I recently found out about Google Co-op. It allows you to create your own web search, or as many different searches as you want. In other words, you tell it which websites to search, and it will search just those sites or simply put those sites first. Take all your favorite biblical resources sites, create a search, and then add it to your Google homepage (or bookmark it) and share it with others.
I’ve played around with a few, and I think this has real potential to be very helpful! Try out my Reformed Theology search, and feel free to edit it by adding other Reformed sites. Maybe we could start an MP3 search for sermons and lectures. Lots of potential here. Let me know if you create any.
