Join Platy’S Readwise Highlights

You could put a PURL into a catalog record and if the URL it pointed to needed to change you changed the redirect on the PURL server, and all the places that pointed to the PURL didn’t need to change. It was a beautifully simple idea, and has influenced other approaches like DOI and Handle. But this simplicity depends on a commitment to keeping the PURL up to date

ISO 4217 is a standard first published by International Organization for Standardization in 1978, which delineates currency designators, country codes (alpha and numeric), and references to minor units in three tables:
Table A.1 – Current currency & funds code list[1]
Table A.2 – Current funds codes[2]
Table A.3 – List of codes for historic denominations of currencies & funds[3]

Paper had no Back or Close buttons.
We held the belief that early ideation is about always moving forward. This is the “Yes, and…” philosophy that unlocks creative flow. We took this literally and designed a navigational model where you never had to back out of a menu but would simply move on to the next thing.
At a time when most apps relied on nested menus that had you diving in and out (a la iPod), we came up with a spatial navigation model that you moved through with gestures. This meant you always had context of how you arrived and could see where you might go next. To close, a small pinch would take you back to your pages and a big pinch would take you all the way back to your row of journals. One single, interruptible gesture years before iOS’s fluid home swipe gesture.
