The Denbigh Commercial Ruled Book was a steady presence in Edinburgh for over 100 years.. but this collection is sadly no longer in production.
The books are described as "traditional strong well-made books with section-sewn pages printed with faint blue rullings on quality opaque paper and bound into rigid case-bound covers." We would add that the lines are actually a very beautiful blue-green and that the books have a speckled blue edging (varying in brightness from piece to piece). Also, due to the binding technique, the books open fully flat.
