The ever-so useful Pocket reference, Review of HTML5 Pocket Reference by Jennifer Niederst Robbins is in it's fifth revision, and not a lot to say about it. it's a consistently neat dictionary reference of the HTML5 tags and attributes, that I personally find handy to have by my side when I do HTML stuff, as do the seasoned HTML programming monkeys. Whilst it has no bells and whistles, the book has the precise structural flow of element, description, usage, attributes and example, so you know exactly what each element does, both in definition as well as contextually.
The book is under 200 pages, easy to read and find and extremely concise, as you would want any dedicated reference book. And I prefer having such books as ebooks because it makes searching for specific elements a lot quicker, by clicking or pressing an element in the index, or Command & F'ing the specific element I am after.
Prior Knowledge: HTML knowledge is assumed, as this is a reference book, although it would suite the novice as well as seasoned HTML programmers just as well.
