When you have a citation from a reference list for an article that you're trying to find, there are a couple of different ways you can try to track down the article.
Example citation: Cortesi, F., Giannotti, F., Sebastiani, T., Panunzi, S., & Valente, D. (2012). Controlled‐release melatonin, singly and combined with cognitive behavioural therapy, for persistent insomnia in children with autism spectrum disorders: a randomized placebo‐controlled trial.

The Get VText system is a method for looking up, and connecting to when possible, full text resources. It works best with journal articles, but can also work for books and book chapters, newspaper articles and other text resources, data sets, streaming videos, and more.
The button or link appears in databases where the full text of your resource is not present.
