allisbns 0.1.3

Works with Anna's Archive's ISBN code files

allisbns

allisbns is a Python package to work with the packed ISBN codes from Anna's Archive. It helps you to examine, manipulate, and plot such data that represent the largest fully open list of all known ISBNs.

Introduction

Anna's Archive, besides books and datasets, provides a large amount of metadata from different sources (including WorldCat, Google Books, the Chinese collections, and many others). Such an extensive collection presumably represents the largest openly available metadata about all known ISBNs ever published (see the figure below).

The derived metadata, periodically published by Anna and the team, includes the packed ISBN codes, a very compact representation of all ISBNs with distinction of original data sources: it can tell you what ISBNs are available in a dataset.

After the visualization contest, the beautiful interactive viewer exists to explore all ISBNs. However, sometimes you need more imperative control over the available data: check many ISBNs at once, analyze selected regions, compare different dumps, plot custom images, etc.

Installation

The package is available on PyPI:

pip install allisbns

To include optional plotting support, install it as:

pip install allisbns[plotting]

Quickstart

Download data

The package works with datasets provided as bencoded files named as aa_isbn13_codes_*.benc.zst. Such files are located in the codes_benc directory within the aa_derived_mirror_metadata torrents. One file contains ISBN codes for all datasets (collections). See here for more info about codes.

Work with datasets

Create a dataset from the downloaded file with ISBN codes:

    >>> from allisbns.dataset import CodeDataset
    >>> md5 = CodeDataset.from_file(
    ...     source="aa_isbn13_codes_20251118T170842Z.benc.zst",
    ...     collection="md5",
    ... )
    >>> md5
    CodeDataset(array([    6,     1,     9, ...,     1, 91739,     1],
      shape=(14737375,), dtype=int32), bounds=(978000000000, 979999468900))

The md5 collection represents files available in Anna's Archive. All available collections are:

'airitibooks', 'bloomsbury', 'cadal_ssno', 'cerlalc', 'chinese_architecture',
'duxiu_ssid', 'edsebk', 'gbooks', 'goodreads', 'hathi', 'huawen_library', 'ia',
'isbndb', 'isbngrp', 'kulturpass', 'libby', 'md5', 'nexusstc',
'nexusstc_download', 'oclc', 'ol', 'ptpress', 'rgb', 'sciencereading', 'shukui',
'sklib', 'trantor', 'wanfang', 'zjjd'

Query one ISBN:

    >>> md5.query_isbn(978_2_36590_117)
    QueryResult(is_streak=True, segment_index=8652142, position_in_segment=0)

Check many ISBNs:

    >>> md5.check_isbns(range(978_2_36590_000, 978_2_36590_999 + 1))
    array([ True, False, False, ..., False, False, False], shape=(1000,))

Get all filled ISBNs:

    >>> md5.get_filled_isbns()
    array([978000000000, 978000000001, 978000000002, ..., 979999377030,
       979999377160, 979999468900], shape=(16916212,))

Crop the dataset to some ISBN region:

    >>> from allisbns.isbn import get_prefix_bounds
    >>> start_isbn, end_isbn = get_prefix_bounds("978")
    >>> md5.reframe(start_isbn, end_isbn)
    CodeDataset(array([6, 1, 9, ..., 1, 2, 2],
       shape=(14503001,), dtype=int32), bounds=(978000000000, 978999999999))
