A reader has just emailed me today to tell me that it is possible to link to my listings on Alibris. Very kind of you, Matthew! (Sorry you couldn't leave a comment here. Hopefully I've repaired that now.)
So, if you were of a mind to do so, just click here and it'll take you to the books I have for sale on that site.
In fact, it's interesting to come into the Alibris site in such a way. It's not a page I've ever seen before. It divides up your product into categories, and gives you a better way to browse. Just goes to show what's available!
