Note that the above information except for mirrors is fecthed as is from Libgen and it is up to the uploader of the books to include the metadata of the books.

Optionaly a destination Path can be passed with the url using dest_folder argument. The output of the download method is a Path to the downloaded file.

async def download():
    q = 'japan history'
    result = await lg.search(q)
    download_location = []
    path = Path('Downloads')
    for item in result:
        file_path = await lg.download(result[item]['mirrors']['main'],
                                      dest_folder=path,
                                      progress=progress,
                                      progress_args=[
                                          result[item]['title']
                                      ])
        download_location.append(file_path)
