Booklady:
If you're there on a weekday, the University bookstore will be open. As you come in thru the main portal (stone arch) you'll see it on your left (as I recall). They didn't seem to have any problem with us shopping there as long as we spent a few mil (pesetas).

There's a chance I'll visit Alcalá de Henares next month too... but wondering what mode of transportation I'll use; the bus or the train? Hmmmm... Well, whichever I choose, I have the information I'll need by Itchyfeet (for bus) and RENFE has all the other information.
