This is a simple search facility which will look for the words you specify in the documents in this site. Use it to search for titles when you don't recall the author, or for other text. It will look for parts of words too, but it takes you very literally so be careful about spelling. However, it won't distinguish between upper and lower case, so Roberts, roberts, and ROBERTS are treated the same.
Once it finds pages containing your text, click on them to view them, and
use your browser's find feature to jump to the words of interest if you
aren't scrolled to them already.
