One of the first comments I received after the first edition of Guide to the Building Regulations was published back in 2010 was that it would be very useful to have the book available in an electronic format, so it could be used on site. Back then, an ebook edition didn’t seem feasible: the book has so many large tables and illustrations that putting it out on something like a kindle or nook was impractical.
But the technology advances and RIBA Publications have issued a number of their books as ebooks, in PDF format using Adobe Digital Editions. One of the first books available in the new format is the third edition of Guide to the Building Regulations, making it easy to take the book on site.
Also, at the time of writing, there is a 20% discount on the ebook edition.
