This sounds like a use-case inventaire.io ought to support. I'll try to ask them about it. They use wikidata for filling up book metadata.
Otherwise, as stated elsewhere in this thread, Zotero can usually find books with very little information:ISBN or title. It might be worth trying to set up an OCR with it.
In any case, if you go to the length of taking a picture for each book, you might as well save them and make the dataset public, for OCR training purposes (and a second pass).
There is also the mechanical Turk option if you go this way.
And as someone stated already, you should plan the physical layout in advance.
yep, inventaire.io could help there, to some extent: they could scan books barcode in bulk from the webapp https://inventaire.io/add/scan , which should find data for most books. But then it gets tricky for books without barcode/ISBN has they would probably have to fill the data manually, which can be quite some work for large inventories. No plans to add OCR, yet ;)
