In addition to the above problem with 7xx analytics in particular, 7xx's provide an even more general problem. They might be a uniform title for work cataloged (I can't figure out in what circumstances they'd be this, normally the uniform title is in 140130 or 240, but apparently sometimes it's in a 730. serialsSerials?). They might be a 'citation' (controlled heading) to a related work. They might be an analytic. They might be something else entirely. Is there any way to know what it is? Got me. Without knowing what it is, it's hard to display it appropriately for the user.

How do I know if a 730 is a uniform title for this work, or a related work? = = Figuring out 'form' of work in general == At first you see that maybe you can do this with an 006. Look, it's got a first byte that tells you if it's a 'book', 'musical recording', 'non-musical recording', etc. But then you realize that most records don't have 006's. What are the rules for what record will have an 006 and what won't? I have no idea where to find them.  Where in the MARC record does it tell you this sort of thing? Seems to be spread out across a buncha different fields, with what fields will be present in a given record kind of hard to predict.  Telling the user if something is a 'book' or a 'musical recording' is a pretty useful thing to do, no? I believe it's possible from MARC, but it's sure not simple, and I'm not sure becuase I haven't figured it out yet.  Okay, wait, I didn't want the 006 at all, I really wanted the 008. Okay... The 008 tells me the bytes mean something different depending on whether the record is a "Book", "Music", "Computer File", etc. Where do I tell which it is, to see what the bytes mean? Still working on it. = MARC and Cooperative Cataloging: False economies Economies =

Much science fiction, to give an example, exists as short stories that end up in libraries as in anthologies. Without even a 505, it's impossible for a patron to see if the library has 'The Cold Equations' by Tom Godwin.
