Right yeah erm so that can be, that can be a bit awkward but still some of the older stuff can give you a bit of a grounding in, in, in, in, in, in what it's about if you can find anything relevant and sometimes you've just got to sort of wander round the library and pick things up off the shelves like at random and see, see if you can find something in the index or find something in the contents pages that sort of vaguely coincides with what the  you know what's been talked about in the class that week erm sometimes if you keep looking you might actually be dead lucky and find one of the recommended books has actually come back in erm  you may find that you've got to be a bit flexible about that because, you know, if a topic's dealt with in November you may not get a chance to see the book until  you know kind of, I don't know, February or something, you know I mean  so it, it sometimes does mean you've got to do the reading like a bit displaced from the  from the classes
