Another interesting site! I had used it before and the other day I was checking up on an item re Frank Sargeson, the authors files are useful.

I have been looking at Rollyo but so far I have found it difficult to find a subject which is as spell binding as some other sites... I find the principle attractive but the resources limited. Maybe if I was travelling overseas it would be handy to check hotels and cheaper deals - I did an experiment with San Francisco and it gave a couple of ideas. I also tried the rare book site mentioned but was disappointed- I tried two obvious ones but they were not listed. I was also irritated by the commercial setup. I had trouble following the instructions to set up a searchroll (that was fine) but transferring it to my blog problematic!
