The Book book

Or ‘The book Book’.  Either way, a brilliantly simple idea, thanks B. 

Instead of – or rather as well as – keeping a notepad beside you, on which anything from possibly-to-be-used-in-future-blog-post-quotes-from-newspapers, via debugging instructions or memorable song lyrics or transient phone numbers to data concerning books can be jotted, instead you can maintain a separate notebook (it should preferably be hard covered, A4) in which you write anything you like or dislike about books you’ve read, recently or in the past, or want to read in the future, or feel you should read, the main rule being that there are no rules, at least I think that’s how it’s meant to work (there may be a few others about inordinate punctuation and sentence length, also about the importance of strictly confining the scope to books, resisting the temptation to extend it to music, films, and other media –  otherwise running the risk of going full circle and ending up with a notepad beside you, on which anything from possibly-to-be-used-in-future-blog-post-quotes-from-newspapers, via debugging instructions or memorable song lyrics or transient phone numbers can be jotted, or even data concerning books), but I'm not sure about that, a bit more analysis might be needed, so don't wait up. 

Like I said, brilliantly simple.
