I added a book for you. I like the idea and design. I think there should be another column that stores the location to the book. I think that the homepage should just be the link to the book's website. Maybe an upload option to add the pdf or a link to the direct download.
I'm thinking of adding an "Additional notes" box to the book profile for that sort of thing. Recent events made me shy away from any sort of hosting, but I definitely see the value in direct download links. I saw your submission :) Thanks for trying it out. Hope you'll find it useful.
