about Skim Mar 2016

Skim is an excellent PDF reader & annotator. From Skim's entry, here on alternativeto, it looked as if it hadn't been updated in years. Visiting the logs show that the project is alive and well. Good thing!

about Skim Jun 2011

I really like Skim. My ebooks look great on it. It has opened all the .pdf's I've thrown at it. There's plenty of viewable options and is very clean. The only problem is there is not a windows version. I have and iMac that I use this software on but cannot use it on my laptop PC's.
