I would recommend looking into the townhomes rented by Campus View Apartments on Morgan Drive in Suncrest. Although it is not within walking distance of the hospitals, it would be a very short drive (1-3 miles). Actually, you probably could walk if you wanted to, but there aren't may sidewalks and it's a bit hilly over there. Most of the apartments in the Health Sciences Center/stadium area, and anywhere that is within walking distance of the hospitals will be FULL of students. Just something you should be aware of.
My husband and I rented a townhome on Morgan Drive (3 years ago)and we loved it. This isn't student houing-- there are a lot of singles/grad students, young families, and some older people in a more established, residential neighborhood. The house itself had 2 nice sized bedrooms (with nice closets), 1 1/2 bathrooms, equipped kitchen, dining room, living room, washer/dryer, a patio, balcony and off-street parking. When our lease ran out mid-2004, we were only paying $600/month, plus utilites.
As for the libraries in Morgantown, they are both relativley new. The Morgantown public library underwent a renovation in the early to mid-1990's and the Downtown Campus/Wise Library (WVU's) was remodeled and had a new addition in 2002ish(?). They are both very nice and should have most everything you would expect in a library.
Here are the library links:

Good luck with your move and hope this helps!
