LibDNB

This project is heavily inspired by calibre-dnb

About

I needed a way to fetch basic book metadata from the German National Libraries "API", I found calibre-dnb, but it is not suitable for my usage case, so I modified it. You can visit the portal here: portal.dnb.de.

Get started

Obtain Token

You need to apply for an API-Key at schnittstellen-service@dnb.de in order to get access to the catalogue. This library uses the SRU-API, you need a SRU Access Token.

Installation

pip install libdnb

Usage

Code Example:

import libdnb

dnbclient = libdnb.LibDNB("Your-SRU-Access-Token-Here")
result = dnbclient.lookup("9783346111098") # ISDN, Title, or any other metadata to search for here
if result: # Result might be None if nothing was found
    print(result["title"])
