quite a bit, i can just tell you from being a student was a student where you go online to get to the books thru the catalog but if you want a magazine or a newspaper you had to use print resources and then as i became a graduate student you had the online databases but still there was no full text so you would use those instead of the print indexes you use the online databases to search and then you still go to the print magazines and journals and then when i became started working at the library you had the online databases everything you got thru online and even now there are streaming videos we have we are starting to have more streaming videos where students will instead of coming and checking the dvd they'll actually watch and view it online from home or from the classroom so everything changed even how they do the online tutorials we do a lot more videos than when we were able to when i first started just because the software is better do a lot more for a lot less
