I am currently working my way through Foundations of AJAX (Books for Professionals by Professionals) by Ryan Asleson and Nathaniel T. Schutta.
Although this is the only Ajax book I have read even part of, so far, I would thoroughly recommend it as an introduction to Ajax.
Previously I most recently completed reading Λεξικο Νεοελληνικηζ Γλωσσας - which is hard going - It's a Greek dictionary, and is written entirely in Greek.
I continue referring to it from time to time for explanations of things, but as friend of mine in Greece once said: "You won't find the Greek word for "Friday" in the book, because if you are capable of reading a dictionary, you already know how important Friday is!"
It is true that "Friday" (or Παρασκευή as it is in Greek) is not in this dictionary. Every other day is!
ISBN 960-460-279-9 is available from bookshops in Greece for around €11.70 euros - but does not appear to be available from Amazon.
I rarely make enough time to read actual books nowadays - as most of what I read is I.T. related, and online, but some of the books i have read are here:
• Foundations of Ajax - by Ryan Asleson & Nathaniel T. Schutta - the only Ajax book I have read, but I would thoroughly recommend it.
• Dirk Gently's Holistic Detective Agency - by the author of Hitch-Hiker's Guide to The Galaxy
• The Hacker's Handbook III (amazon link) by "Hugo Cornwall" - one of the first I.T. security books i read (way back in the 1980's). From this book I learnt the term "social engineering"
- and I would go as far as to say that this should be REQUIRED reading for any individual intending on using I.T. in business or in their career."
