Please bring back the .pdf download for your free library books.
I can't download the kindle version, because I don't have a kindle, or an iphone or an ipod.
I can't download the B&N version because I don't live in the USA.
I might be able to download the Sony version, if I install their software, or it might not work eiter. Who knows? However I really don't want to install a 5th ebook software on my computer. The four formats I have already are enough.
