greywether's spreadsheet is excellent. All the info you could want at a glance -

Especially good for me as I have all the books that are referenced on the spreadsheet. Good work! And a very valuable resource whilst there I'll wager!

So, these 59 on the list are the recognisable 'Recumbent circles'. I see Burl has 67 listed as 'destroyed or unrecognisable' and 11 or 'dubious' origin.

My 'hit list' must therefore be based on this 59. The '59 Stone Circles In Aberdeenshire' of Chapter 8 of TMA.

Bring it on! (and other such youthful phrases someone of 38 shouldn't say)
