Abosulately love Paperpile and it has made my life far far easier since returning to school. Started to get some support on this particular issue a while back, but I didn’t follow up:
When using Proquest or EBSCOhost databases for research (from behind a proxy), I can’t get Paperpile to detect the full text pdf documents from with the search page. I end having to find the paper in google scholar in order to save the metadata in paperpile, then open or download the pdf manually and attach it to the existing reference. This work around works, but it’s a significant hassle as these are the two main databases I currently have access to.
