In this world of MARC (s/MARC/hurt) I call that an embarrassment of riches. I've spent some bit of time parsing MARC, especially lately, and just the fact that Summon provides a normalized date element is HUGE. That potentially takes that load off of your application, should it be forced to absorb native MARC. This is the old Garbage In/Garbage Out (GIGO) issue. Case in point: just today I discovered that we have at least 1,600 856 fields in Worldcat that have the pipe symbol "|" in the second indicator position instead of the numeral one. Right, that means there are rocket scientists who thought the documentation was indiicating a pipe symbol in that position. We then have granularity issues, punctuation issues, and variance in practice. And that's just for starters. Huge props to Summon for trying to tackle some of these things, as we are attempting to do as well. Roy
