Have you noticed this?
Books are steadily increasing in size, according to a survey that has found the average number of pages has grown by 25% over the last 15 years.
I have to agree but as the article in The Guardian conjectures, this may have something to do with the growth of electronic readers and digital editions. About ten years ago I experienced a painful strained wrist and coincidentally read The Tale of Genji: do you suspect there was a connection?
I have always treated big fat books differently from the more manageable volumes. Until fairly recently the size of the book was involved in my decision whether I bought the book or whether I requested it at the local library. Big books took longer to read, so to avoid those exorbitant library fines, I often would simply buy the book and take my time reading it.
