Download a book as PDF from https://www.hanser-elibrary.com/
Project description
hanser-py-library 
This tool downloads a book from https://www.hanser-elibrary.com saves them to a PDF File called -.pdf. If the book's title contains characters that aren't allowed in a filename it will be saved as -.pdf. If files with that name already exist the number of existing files will be appended to the chosen file name like this (#).
By default the merged book will be saved in the directory from which the program was called, but you can provide a custom output directory.
If a complete book pdf is available, the tool will preferably download that file, otherwise it will download each individual chapter and merge them into a single file before saving. Unfortunately, this leads to links within the merged book (e.g. chapter references) being broken.
The tool will check whether you are authorized to access the book before downloading anything. If you are unauthorized, the book will be skipped.
