Shane Lems of Reformed Reader has some great insights into how to utilize the internet for finding good theology:
Finally, I’d recommending using Google as little as possible when doing biblical/theological research. Google’s methodology in finding websites might be helpful in some areas, but not theology. Google works with clicks and cash; good theology isn’t determined by popularity or money, but by Scripture as read and interpreted in and with the historic Christian church. The top search results on Google are not necessarily the best sources for research and study. Rather than Google, email your pastor, elder, or another wise/mature Christian and ask them where they would recommend getting reading material on a certain subject. Or, look for information on websites whose authors are accountable to elders, creeds/confessions, and/or denominational standards.
As I’ve said here before, I actually do very little research online, and when I do it, I stick to websites like CCEL.org, monergism.com, puritanlibrary.com, and opc.org – excellent sites which host previously edited and published documents that have been digitized.
