The Notebook by Roland Allen review – notes on living by [[Sukhdev Sandhu]]

Not so much of a review as the dumping out of most of the reviewer's highlights from the book. I get the impression that he at least read it and paid attention, but what did he actually think of it?

While I love a great notebook as much as (more than?) the next person, a lot of the notes I take are specifically for filing into either my zettelkasten or index card-based commonplace book for later re-use. Sadly there's not a lot out there in the 4 x 6" format, so I've been able to use some book binder's glue to fashion my own "index card notebooks" which are dissemble-able for filing into my card files for cross indexing. The best part is that I can choose the paper and what's printed on it (blank, lined, grid, etc.) for use with my favorite writing media including fountain pens. I've been doing this for a while and it's working out pretty well. More details: https://boffosocko.com/2022/12/01/index-card-accessories-for-note-taking-on-the-go/

Custom made notebook comprised of 4 x 6" index cards glued at the top with book adhesive surrounded by the binder clips and Lineco glue and paint brush used to make/bind the notebook. Arrayed around the "notebook" are a Lochby pen wallet and carrying case.

I've recently begun adding a chipboard backing to have a firmer writing surface while on the go as well as for inserting into a custom made journal cover/case/wallet in the future, though I've yet to find something off-the-shelf for this. Maybe an A6 cover with some extra margin for error in the size difference?

Has anyone else done this? Suggestions for improvement?
