>The problem with these lab books is that they're often the personal property of the scientists and, as such, almost a sort of diary
Further complicating things, individual researchers don't actually own the books. Often, an institution or the lab owns the rights to the book. This can make individuals who are otherwise keen on "open science" hesitant to place copies of this information in a publicly accessible place.
See page 4 of this manual from the NIH (National Institutes of Health) about the ownership of notebooks.
Everything on that page is stuff you're going to find in a grad student's lab books, which are their property. This document is basically a primer for people transitioning into paid research where the lab-books become lab property. A huge proportion of research, especially in less commercializable areas of fundamental science research, is done by students (because they're cheap). This means the kind of lab-book described in your link is probably less common that you might expect!
