I'm curious what's going on here, it doesn't make any sense.
Do you just mean that your MARC file has more than one 856 in it? That's
what your pasted marc looks like, but that is definitely legal, AND I've
parsed many many marc files with more than one 856 in them, with
ruby-marc, it was not a problem. I do it all the time.
Or do you mean your 856 had a newline ("\n") in it? I don't know if
I've ever tried that, although yes, it should be legal. But if
ruby-marc has a bug there, yes it needs to be fixed.
What form is your marc in that you are parsing with ruby-marc? marc21
binary? marcxml? Or are you actually trying to parse what you pasted
in, that weird marc-as-human-readable-text format? I vaguely recall
ruby-marc having a method to parse such marc-as-human-readable-text, but
I'm not sure if it's actually a _standard_ at all, so I'm not sure if
it's possible to say what should or shouldn't be legal in it.

Thanks a lot Richard,
So I guess my patch could be ported to the source code of ruby-marc,
Let me know if interested,

I'm no MARC expert, but I've learned enough to say that yes, this is valid
in that what you're seeing is the $q (Electronic format type) and $u
(Uniform Resource Identifier ) subfields of the 856 field.

You'll see other things when you get multiple authors (creators) on an item
or multiple anythings that can occur more than once.

I'm using ruby-marc ruby parser (v.0.4.2) to parse some marc files I get

The 856 field is splitted over 2 lines, causing the ruby library to
ignore
it (I've patched it to overcome this issue) but I want to know if this
kind
of marc is valid ?
