Citation Pearl Growing Search

For my citation pearl search, I chose to use my initial building block search (see below) in Lexis to find the most relevant hit:

I got 455 hits. My search results are as follows.

The most relevant hit was right at the top. An article published in the Western Mail on 10.18.2007 entitled, "Students don't have to enter the library to use it". I clicked on this link to access descriptors.

Only one descriptor jumped out at me. Electronic publishing. I chose this subject as an additional search descriptor.

My results are as follows:

I got 64 hits. Of the initial hits, 1, 8 and 24 were relevant. I would definitely use anothr database to complete this search or vary my search terms next time.
