Hey Terry,
I do indeed have one!
https://github.com/rayvoelker/js-loc-callnumbers
I probably should add some better documentation for this thing, but if you
include that source, you should be able to do things like this ...
//instantiate the call number class
var loc = new locCallClass();
// unsorted list of call numbers
var range_data = ["HB 74 .M3 A4 1963", "H 1 .E77", "HB 74 .M3 A38"];
//sort the range
range_data.sort(function (a,b) {
return loc.localeCompare(a,b);
});
//
If you're looking to store the "normalized" versions of the call numbers
(they're not very pretty to look at) in a spreadsheet, you could use the
method "returnNormLcCall()" ...
loc.returnNormLcCall('DA86 .R52');
"DA0000000.000000086.000000000.R00000000.520000000.000000000.000000000.000000000"
loc.returnNormLcCall('DA506.A2 A4');
"DA0000000.000000506.000000000.A00000000.200000000.A00000000.400000000.000000000"
Let me know if you have any questions about it!
