Marking search hits as already read
I did a quick search for Ignatius in "All Resources" and came up with close to 20,000 hits.
Yes I can refine my search. However, I'd like to know is there any way to mark those resources that I have read with "an already read" tag.
So, let's say I had 75 hits on a particular search query and I read 50 of those hits. I then close off L6 and re-open at a later time.
I then do the same search again as above (75 hits), but of course I have forgotten those resources that I had previously read.
Now that takes so much time to start re-reading and then to realize, oh yeah, I read this already.
So my question is this: Is there anyway to mark those 50 previously read articles with a tag that tells me that I had already read them?
I know about the show history option, but short of that is there another way.
