I don't know if this was already known, but just in case it isn't...

I've been looking for the book "Citrus Varieties of the World" by James Saunt for a while at local book shops but without success.

The book can be found on the internet at a fairly high price. Even second hand copies are pretty expensive.

So I contacted the publisher and they told me I could order the book directly from them.

If you're interested in obtaining the book, check this web site...
http://www.sinclair-intl.com/pages/info_pages/citrus_varieties.html
...and send a mail with a request to the address provided at that page.

I'm currently awaiting the arrival of my copy.

James Saunt, the author of the book, is now retired but he still has several boxes of the books at his house.
At one time I was selling them through my website at a considerably reduced price, but I found the process of packing, mailing and arranging for payment was quite time-consuming and tedious. I think I sold 60 copies over a period of two years.
I hope your copy arrived safely and you found it useful.

The book arrived in good shape, shortly after the publisher received my payment.

The contens are actually very similar to information that is written on web sites like http://users.kymp.net/citruspages and http://www.citrusvariety.ucr.edu
