Specialized Indexes

A specialized index like www.biblegateway.com is very useful to those who know of its existence. For quickly finding a passage when I don't recall its chapter and verse reference, Bible Gateway is a lot easier to use when I am sitting at my computer than going to the shelf and thumbing through Strong's Concordance. And if I do need the referencing of Strong's, I can now use a tool like www.blueletterbible.org to provide many of the notes. The biggest problem with such specialized tools is becoming aware of their existence, since they will not acheive the name recognition of a general interest product such as Google.
