Ask4Hearts and 2CIF (version 1.2) are up on BridgeMatters:

Ask4Hearts is the companion of 2Dlay (http://www.bridgematters.com/2dlay.pdf) for minor suit openings - used for game forcing balanced hands, and some other hand types, to find out more about opener's hand, and often arriving at 3NT.

2CIF provides a common structure to all 1X-2C bids, using 2C as game force asking bid. The approach does not use common relay structures, as it is focused on getting to the right contract without disclosing too much and usually making responder declarer. This is complex, and I recommend partnerships try out Ask4Hearts for something easier and quite useful.
