References for the list

I have been asked what references I used when compiling this list.

The first port of call was my friend Betsi's list, which is her adaptation of a number of other lists.

I altered it according to my own ideas to make it more international and include more contemporary works. I also discussed it with people on the BookCrossing forum who gave me lots of ideas.

I had a look at the BBC Big Read but this was not particularly useful for my purposes as it is a) based on popularity with the general public and b) for all time not just the twentieth century.

The Folio Society's books of the 20th century is worth a look but it's not all fiction. Maybe that's one for another project?

There are also the following lists:

• Time magazine
  
• Random House
  
• The Obsever (but again, this is a list of all time not the twentieth century)
  
• There is even a list of lists
