Bookmarking a PDF article inconsistency
I am currently doing a literature review that requires me to analyse numerous sources for information. Most of the time when I bookmark a kopernio PDF of my desire article and re-opening the bookmarked article works fine. But recently, after bookmarking a PDF article, when I try to access it again there is a message saying the the PDF unbale to be accessed. Despite the fact that i just bookmarked a working link prior. I am then unable to find lost PDF.
