There are some normalization transforms which allow you to ASCII sort call numbers.  A quick search gives me:

The Alma system (from Ex Libris) has a normalization algorithm for their analytics, described at https://knowledge.exlibrisgroup.com/Alma/Community_Knowledge/Understanding_Normalized_Call_Numbers_in_Analytics.

A program lccnorm, https://metacpan.org/pod/distribution/Biblio-LCC/script/lccnorm.

A ruby gem, lcsort:  https://github.com/pulibrary/lcsort

I also see modules for Perl, Python, and others.

Subject: [CODE4LIB] compare LC call number

Is there any good existing scripts of comparing LC call numbers to determine which one should come first? Javascript or PHP.





Thanks a lot
