LCC

An attempt at providing Library of Congress Classification information in a machine-readable format.

Data

Formatted data will include:

• classes:
  • symbol
  • description
• subclasses:
  • symbol
• topics:
  • ranges:
    • topic number
    • narrowing letter (if applicable)
    • narrowing number (if applicable)
  • description

Formatted data can be found in 'files/formatted'.

Currently, the only format provided is json data of the form:

{
    CLASS: {
        "description": DESCRIPTION,
        "subclasses": {
            SUBCLASS: [
                {
                    "description": DESCRIPTION,
                    "min_topic": MIN_TOPIC,
                    "min_alphabetic": MIN_ALPHABETIC,
                    "min_numeric": MIN_NUMERIC,
                    "max_topic": MAX_TOPIC,
                    "max_alphabetic": MAX_ALPHABETIC,
                    "max_numeric": MAX_NUMERIC
                },
                ...
            ],
            ...
        }
    },
    ...
}

If you would like data in a different format, contact me and I'll see what I can do.

Parsing

The parser code should work under recent versions of python 2/3. To install its requirements:

pip install -r requirements.txt

To the best of my knowledge, the parser is correctly parsing all files (thanks to many hacks to deal with errors and inconsistencies in the files). It will generate some warnings when it runs because it skips over some lines in the law file.
