Successive Fractions Search

I used ERIC to do this search. I had been using Academic Search Complete and needed a clean slate on the search and in my brain.
S1 = Library 49,204 hits

S2= Library and technology 7240 hits

S3=library and technology and help 419 hits

S4= library and technology and help desk 14 hits

The Successive Fractions search was pretty successful. I found some articles to read to further investigate using an online resource for an online help desk.
