Clever internet search automation

Due to my late father being somewhat of a book worm I have around 1700 books that need to be ‘sorted’

Some are simple novels, worth ‘nothing’, some are historical history on various subjects. Some are worth quite a bit, as are some of the ‘old’ novels.

I have Author Title information typed up, what I figure I need to do is find a ‘quick and dirty’ way to get an estimate of value, whether by a programmed internet search, or what.

Any ideas?

I’ve visited and sent this list to quite a few bookshops, some of which knew him by name, but none have responded. Seems they are all full to the rafters, post covid and are not in a position to buy any more stock at the moment.

Python eg would make it pretty easy to automatically submit info to this search …
