"The BBC's handbooks were published yearly from 1928 to 1987, apart from a two-year break in 1953-1954. Alongside the Annual Report and Accounts, which the BBC is required to submit to Parliament, these handbooks were intended to be a publicly available report of what it did and why."

This work in progress article is a really good insight into the thinking behind the redesign of the BBC's digital services. I particularly like the detail into the inspiration for the grid system from vintage Penguin book cover grids, the idea of an interwoven vertical and horizontal grid system to weave the eye around the content, the more dramatic use of typography focusing on signposting and articulation and insight into their use of 4 new carousel systems.
