Best of the Web: StudyLight

http://www.studylight.org/ is one-stop-shopping for many of your reference and Bible study needs. Traditional reference texts, though useful, are often bulky and expensive tomes that are not even allowed to leave the library. This site contains an entire reference collection including encyclopedias, devotionals, commentaries, reading plans, concordances and a parallel Bible in which you can choose your translations (and language). There are also forums for Bible study discussion. Best of all, it's fully to accessible from any computer with an internet connection!
