Sometimes we definitely want 'items' though, so for example I am in a physical bookstore and see a book I might be interested in, so I buy it, to find out later back home that I already have the very same book - and edition - already. It's a scenario that anyone with some amount of books definitely encountered multiple times, I know I did it myself a few times. :)

Ability of an ISBN search of my collection would have helped me in this case - scanning a barcode is easy enough task to accomplish.

And even if I had a different edition, the resulting title from searching for a different edition would be enough to help me figure out that I should not buy a book I already own.

This reminds me of MusicBrainz, whose database stores "release groups", e.g. the album Nevermind by Nirvana is one, which can have hundreds of "releases", as different media (tape, CD, LP, promo, ...), different countries, later re-issues, etc. [0]

Sometimes these have different catalogue numbers or barcodes to distinguish them, sometimes they don't but they're still different. I've seen releases where the only difference is the label in the centre of the LP, or the back of the CD case has a two-column tracklisting vs a one-column tracklisting. Music publisher uses the same code and says it's identical and yet it's clearly not.

Then there's the "recordings" on an album, which even if they're never re-recorded can still end up chopped up, bleeped or remastered. They're not the same sound. MusicBrainz likes to track when they are exactly the same recording (e.g. the LP recording of a song appearing on a compilation album verbatim) and when they're not (e.g. radio edits of the LP recording). And if we're going beyond recordings by one artist of "their" song, i.e. cover versions, or just plain standards, those are "works", with composers, lyricists, and can be recorded thousands of times by different artists...

I greatly appreciate the pedantry and flexibility for noting down when creative works are the same versus where they differ, in relational database form.

  They actually have a (very new, still alpha, probably not a ton of data yet) database for books:

  https://bookbrainz.org/about

  I haven't looked into what their schema is like, but if it's anything like Musicbrainz it will be pretty comprehensive and easy to pull the data you want out of!

If anyone in the comments is in a similar predicament to the author and would like a book logging app, I will say that I disagree on their judgement of StoryGraph - I've found it a pretty decent interface, the search function is very good, and the (anti)features mentioned in the footnote are incredibly easy to not use, as the creators seem to understand that many of their users have a very strong preference to avoid AI bloat.

I'm not sure we always want 'works'. Sometimes different 'expressions' of the same work are different enough that they don't have the same value.

For example, compare the most recent edition of 'Straight and crooked thinking' with the one published in 1930.

  I don't know that work, but I agree with you in general because of forewords etc. Or even appendices. And translations by different translators.

  I "grew up with" a specific translation of Lord of the Rings into Norwegian, for example. There are two. They are very different. But the editions also differ in whether they include the appendices, whose illustrations are used, and more.

  The most obvious example of this is the innumerable[0] versions of the Christian bible.

  [0] Before anyone says it, I'm sure some bible nerd has numbered them, it's hyperbole.

This also fails to take into account that ISBNs also contain the publisher ID in them. So identical copies of a book could have different ISBNs depending on which markets they are sold in.

  I'm not sure this is the case, I got my ISBN range through my government national library service, I could be wrong but when you let them know what the book is you are publishing they ask for the Publisher name, though I am guessing as the service is free and it only applies to New Zealand books and publications.

  They don't contain the publisher name, but ISBNs are usually purchased in blocks of 10 or 100 or 1000 or whatever by a single entity, which is often a single publisher or corporation.

  However, within the block publishers can assign ISBNs to different imprints.

My state had a reading competition that listed books by ISBN, which was a real challenge for students to track down. Each library had different editions and even different cover art, so if you “found” the book you might not recognise it on the shelf, etc…

I worked on the library systems and one of my innovations was to use the ISBN mapping database of WorldCat to find books with identical content but different ISBNs to help kids find the books on the list.

Over ten years that one SQL join in the code made the kids read an extra million books they wouldn’t have otherwise.

My biggest “bang for buck” in my career!

  That is amazing. For odd reasons I had to get real familiar with ISBN as well. What did that sql command look like if you don’t mind me asking?

If the author sees this comment, https://news.ycombinator.com/item?id=43168838 might be relevant as it relates to catalogue completeness. OpenLibrary is very good, but Anna's Archive is potentially more complete.

The first few para's of https://en.wikipedia.org/wiki/ISBN are a better summary of the issue.

tl;dr; - The ISBN is intended to be a physical Part Number, within the book business. Where "hardcover, or paperback, or trade paperback, or large print, or revised edition, or ..." very much matters.

[flagged]

I read that it's much worse than that, and there are ISBNs that were reused for completely different books.
