I am sorry for the delay in posting.
I recently had a couple of surgeries which haved caused me some "downtime" while I recover.
I've been adding to my library in Ravelry - my Ravelry ID is Brightmeadow.
There don't seem to be a lot of machine knitting publications already in their database, but I have found a few. I have several years worth of KnitWords hardcopy magazine on my (real world) bookshelf. I also have the digital version that Mary Anne Oger published when she closed the magazine, if I can find the CD. It is somewhat clumsy to add the magazine covers by photographing them, and then rotating the photo 90 degrees, then uploading it to Ravelry. It would be really good to know if others have already posted these.
