After finding out that you can now search on FMP on (any) census by birthplace I decided that perhaps it was time to start reading some of their weekly notices and stuff to see what I was missing.
Turns out it was worth my while.

The enumerator summary books images in the 1911 census are now viewable. Plus the household schedule cover, etc. (The latter may have been available for some time, but I've only just found them.)

To view all the 'extras', download the image of the census page, and in the bottom right-hand corner of the screen there's a 'related images' link. Click and it expands for the cover and address of the household schedule (RG14) and then all the enumerator book stuff (RG78).

If anyone has missed the how to 'search by birthplace', you'll find the link at the top of this post.

Sorry, the link doesn't fully work. Scroll down the thread in the link to post #7 by helachau.
