Just uploaded Herbert Croft's emotional letter (shown below) regarding his visit to the room in Brooke Street where Chatterton died.
There are 344 pages, including the index, in Croft's 1786 fifth edition of Love and Madness. Around 150 of the pages are dedicated to the Chatterton story. These pages, along with the pages from the 1780 edition, will be uploaded within the next few days.
In case you were wondering, and you probably weren't, the little paws holding the pages flat when I photograph documents for the website, belong to Leo my ancient wooden lion.
