Maybe if I spent another hour on this site I might 'get it' but time is an issue and I 've had a play around. The NSL instructions were easy to follow and I set up 2 search rolls but am not sure what happens next!
I can see the benefits of accessing your own trusted search engines for a specific passion or interest and the search rolls I had a look at were interesting eg. rare book library search and public domain e-book search but.........!
For reference work in the library would it be the equivalent of our Fitch?
Not a particularly user friendly site.
