i remember when someone sent out an email about that so i search in my email trying to find to see what do they do to find what were the good sources on that it was only helpful to me so when katherine came who is our new public services librarian a few years ago she did some searching she created a wiki for us so lets say dr. evans has an assignment that's and we thought it was really hard to find sources we could type some notes and then someone else later on someone else comes in and oh we have an assignment for dr. evans its this and they can go to the wiki and type it up and then they can see where someone put their notes and then add to it and so it has been really nice.
