This may be weird... but this downloads all the books (just find and extract out all the links to a file)
import urllib2
import urllib
f = open('file.txt')
CHUNK = 16 * 1024
for line in f:
req = urllib2.urlopen(line)
file = req.geturl().split('/')[-1]
file = urllib.unquote(file)
if '.pdf' in file[len(file)-4:]:
with open(file, 'wb') as fp:
while True:
chunk = req.read(CHUNK)
if not chunk: break
fp.write(chunk)
