1. books project
- making a development plan
    - user-facing program vs. code-facing module/class/function/...
    - how does this code look from the CALLER's perspective?
    - top down? bottom up? both and meet in the middle?
    - separate books.py or main program in booksdatasource.py?
    - stubs
    - iterative development with very small iterations

- command-line argument parsing

- parsing CSV files with and without the csv module

- BooksDataSource
    - why have it at all?
    - do you want to preload the CSV file contents
        or just remember the file name and parse it in
        books, authors, books_by_year?

- the "with" construction in Python

- special methods in Python: __eq__, __lt__, etc.

- pay attention to the stuff in my repository
    https://github.com/ondich/cs257_2022_fall

    (books2.csv, authors2.csv, books_authors2.csv will
     be relevant in a couple days)
