Installing

Python 3 (OS Agnostic)

Check that you have Python 3 installed and available on your shell. The following command should return something like Python 3.8.5.

python -V

Windows users: Make sure to enable the "Add to PATH" option when installing Python.

Now you can install using pip with the following command.

pip install hathitrust-downloader

Which allows you to interact with the downloader from the command line:

hathitrust-downloader --help

Windows Executable

There are also Windows executables available. Download the downloader.zip from releases and extract it. Then open a shell, e.g. cmd or powershell, to the directory where the ZIP is extracted. The easiest way to do this is by opening the folder in Explorer and right click while holding shift, now select the option "Open PowerShell Window Here".

The executable is bundled with Python and all other dependencies, hence you do not need to have anything installed. Now the tool can be used like:

.\downloader.exe --help

The help should give some instructions on how to use the tool:

Troubleshooting

No Progess / Progress Bar is Stuck

Make sure that you can access books on HathiTrust. Try to open a book in your browser to see if everything is working fine. HathiTrust can require you to connect from an American IP. In addition, they limit the amount of pages you can download to 15 every 5 minutes. When you hit that limit you will need to wait, the tool will automatically wait and resume when the timeout is finished.
