Okay, I changed the layout again (less work this time, the backend code stayed the same
), the text is now the same size as before or slightly larger and instead the cards as a whole are larger.
The added/published text is now the same size it was before the first change, but I dont think it is necessary to make it larger still as most of the time this can be considered background information. I think the slight benefit in visibility would be outweighed by the increased book card size, as this would mean fewer books would be visible at one time.
