More Info on Searching CLE Books Unbound
I had some concerns about the limited search capabilities but Books UnBound project coordinator, Kristin Huotari, tells me that a more advanced search is in the works. She says:
We are in the process of integrating our Google Search Appliance into the online books reader, and providing for searching across all titles. Until this feature is completed (which should be fairly soon), you can use the WisBar.org Legal Research tab for better searching. Our Legal Research site uses the Google Search Appliance and should help you get the relevant results you are seeking for Books UnBound.
