Dr Paul Leyland

No need to stick with your copy except for sentimental reasons.  Second-hand copies are dirt cheap.  I’ve five different editions in the library, none of which cost me more than a few pounds.  The first (1910) edition was was given to me by a friend whose astronomer father had died recently.  It’s been well-used for the last century and ought to be re-bound professionally.

If you wish I can put you in contact with a guy who is down-sizing his library and from whom I bought the Tycho catalogue.  He had a copy of Hans Vehrenberg’s “Photographischer Stern-Atlas” which goes down to mag 14 or so.  Don’t know whether it is still for sale.
