liblibrary-callnumber-lc-perl
utility functions to deal with Library-of-Congress call numbers
Description
Library::CallNumber::LC is mostly designed to do call number normalization, with the following goals: * The normalized call numbers are comparable with each other, for proper
sorting
* The normalized call number is a short as possible, so left-anchored
wildcard searches are possible (e.g., searching on "A11*" should give you
all the A11 call numbers)
* A range defined by start_of_range and end_of_range should be correct,
assuming that the string given for the end of the range is, in fact, a
left prefix
That last point needs some explanation. The idea is that if someone gives a
range of, say, A-AZ, what they really mean is A - AZ9999.99. The end_of_range
method pads the given call number out to three cutters if need be. There is no
attempt to make end_of_range normalization correspond to anything in real life.Upload more screenshots
