Bookshelf DataBase   (+3, -1)  [vote for, against]

The purpose is to identify the most popular books on the planet.

A person takes a photo(s) of their book shelf and uploads it into an online database (anonymously if so desired). Text recognition software reads the book titles on the spines and enters them into a database.

EDIT: Apparently the rest of this is already fully baked... so my invention ends with the Scanning of the Bookshelf.

A person could search for the most popular books. Or, the most popular books containing a keyword ("auto", "cooking", "zebra" etc). One could also use this for recommended books - 150832 people who read "the black stallion" also read "black beauty".

Cross referencing with other databases can add meta-tags to books ("fiction", "non-fiction", "space travel" etc.) - see link for halfbaked database idea (minus bookshelf component)

In recent years, similar information can be gathered from book store sales data - but computerized information of older book sales does not exist. Also, discarded books (firewood) will be eliminated from this database.

List and review your books [colorclocks, Mar 16 2009]

I like it - I've a feeling there's may have been something discussed here before to to with analysing the contents of a photo of someone's bookshelves - and we must be on the cusp of it being an available web-utility (upload your bookcase, and we'll tell you what you've got type deal) which would attract millions.

Baked. LibraryThing doesn't have the text recognition from photo thing, but it has everything else.
