    Green Heron is a great resource for anyone who has limited access / time for doing literature searches or finding information more generally. They helped me with 3 fast-turnaround projects, and were extremely responsive, flexible, fast, and willing to tweak their searches based on my evolving specifications. I highly recommend them.​
