Primal Blueprint

[[deleted user]]

The Primal Blueprint has been revised and expanded in a new release, and normally I'd say this is clearly just a new edition of the same book. However, in this case, the title has been changed to The New Primal Blueprint. I'm not sure whether to add this as a new edition to The Primal Blueprint or to make it a separate book due to it having a slightly different title.

Can anybody clear this up for me?

Title of the book is irrelevant. It is the content that matters. How much was it expanded?

If it is more than say 10% then it would be a new book. And if so it would need a librarian note so that another librarian doesn't combine it in the future.

10% is pretty low, actually, and not enough. But in this case, it seems to have gone from about 300 pages to over 500.

How much do you think it needs to change to be considered a different book? Inquiring minds need to know :)

There is no hard and fast rule. It depends on a lot of factors.

OK. I'll keep it in mind.
