DC Comics has all of it's most recent trades available day and date on a library lending service called Hoopla, where you use your library card number to "check out" the trades digitally and then "return" them. Limited to 6 a month, but pretty cool.
Marvel offerings on Hoopla are much more limited (Basically just a few older trades and collections). Any idea why this is? Is any greater availability imminent? A lot of X-Men titles have come out and they are too expensive for me to keep up on, so it'd be useful to catch up on those.
