The Library is actually pretty easy if you use the right tactics. Here's a few that I use:
When possible, kill the flood one at a time as they come around corners (with the shotgun), rather than running out in the middle of a dozen flood and getting killed.
The pistol and shotgun are the ideal combo here, not the assault rifle and shotgun. Pistol them from a distance and use the shotty up close. Use the melee attack to kill the little guys.
Use the human pistol to kill them from a distance. Always shoot the carrier forms first. They will explode and kill any nearby combat forms. If you kill them from a distance with the pistol, you're in no danger of getting killed. If there's a large crowd, lob a frag grenade into the middle.
Watch out for carrier forms (the pregnant ones). Keep an eye on your radar in case they sneak up behind you. NEVER let them blow up near you, and always watch out for grenades laying around when you kill them from a distance. The chain reactions can be deadly.
In the room where it locks both doors and traps you in (I think it's on the 3rd floor?), don't try to fight the flood. Hide in the corner, and when a bunch have poured out of the pipes, bounce some grenades off the ceiling (so that they land in the middle of the room) to kill them. They won't know where the nades came from. After a minute or so, the door will open and you're home free, without a scratch! The remaining flood are easy to take out.
When possible, retreat and fight the flood from a distance with grenades and the pistol. The flood are most deadly up close, so obviously your odds are better from a distance.
Don't even bother with the Assault rifle. Sure, it's convenient for the popcorn guys, but otherwise it's a complete waste. Besides, the popcorn guys can easily be killed with melee attacks.
If you do it this way, the Library becomes one of the easiest maps on Legendary (besides The Maw and PoA). :)
