You can download the dataset directly from internet archive using pip install internetarchive && ia configure && ia download --search 'collection:deutscherbundestag' --glob '*.pdf'. This takes quite a while - let it run over night.
If you are impatient, here's a compressed version of the files. This download comes directly from my server and may be slow if many people are using it. I also don't guarantee that it will stay up, or up-to-date. Each of the .tar.gz archives below contains the documents of a single election period (1-18).01.tar.gz
Reminder: Get your own copy of the dataset directly from the official source using pdok-mirror. Please also read and understand the information given at the details page on the internet archive, as it also contains some legal information on what you can and cannot do with the data.
