Is it just me, or does everyone spend aaages reading a textbook because of going off on tangents from other references.

I am trying to read a book just now, and the author has made mention of another book .. one I haven't read. So, I have just had to order the book from the library or I won't really know or appreciate the point my current author is making.

No wonder it takes me so long to trawl thru non-fiction.

There is so much that I don't know. :|
