A sizeable portion of famed astronomer Sir John Herschel's library has turned up in Toronto! Thanks to the dedicated sleuthing of RASC historian Peter Broughton, hundreds of volumes from William Herschels' son's Collingwood library have been identified in the University of Toronto library system. Many of the volumes contain Sir John's own annotations. For a popular exposition of Peter's discoveries, an account of how the books ended up in Canada, and some of the implications of Sir John's annotations, see this recent article.
