The music software company Impact Soundworks has launched a second volume of their Acoustic Revolutions series titled Acoustic Revolutions 2. The library features loops of an acoustic Taylor guitar and are designed to be useful for a variety of styles and genres. The loops, which are organized by tempo, time signature, and key, do not require a sampler to be played and the WAV files can be dropped and placed into any DAW (Digital Audio Workstation).
Acoustic Revolutions 2 is available on Impact Soundworks for $49 and you can buy Acoustic Revolutions 1 + 2 as a bundle for $65. You can head over to the Impact Soundworks website for more details.
