There is a pocket lexicon of new testament Greek. As far as I can tell, this is the only dictionary available at Textkit.
There are some really in-depth dictionaries that are out of copyright. I’d really like to see things like this.
I would also like some concordances.
There is no need to reinvent the wheel, friend:

In principle I would too, but Benissimus has a point. In particular, dictionaries are used differently from textbooks in that the part of interest is a fraction of a page, which does not lend itself well to browsing the pages of a .pdf file unless you have the ability to perform a word search. Making files like that involves much more than just scanning images. And, of course, the really in-depth dictionaries I’d like to see are generally longer than 1,000 pages.
On the other hand, if anyone has an edition of Forcellini, I’d love to see that scanned, just because of its rarity.

How about a useful rarity? Gallica has Du Cange (almost complete) and Maigne d’Arnis. Generally, they have a ton of stuff. I am trying to download what I can, this free of charge business can’t last forever.
Any suggestions?
I know Lewis & Short should be out of copyright. Sure, it’s nice to search it online, but I would not mind having a PDF. The problem is that OUP is still publishing L&S and in case their army of lawyers fails to prove that their copyright is permanent an unfortunate automobile accident would promptly take care of whoever decided to play hard ball with them.
I’m not strictly opposed to dictionaries but there are already so many dictionary resources on the Internet that I think our time is spent best with other types of content.
Also, a dictionary is something that’s most useful in book form so that one can flip through the pages quickly.

I know, Those PDF files are SO hard to flip through! 
And you can use a good dictionary to prop up a car while replacing a tire. PDF file in the same situation? Forget it!
I have printed out almost every book that I felt like flip through. 
Just to revive this dictionary subject - I would still like to see something like Whittaker’s “Words” program for Greek. The online dictionery at Perseus is great, but if you are working away from internet access it is not much help. Also I sometimes find the Perseus site slow or not working properly, especially when trying to use the “input in Greek characters” section. I wouldn’t mind paying for a look-up etext edition of Lewis & Short or similar, providing it wasn’t ridiculously expensive.
This might fall into the “ridiculously expensive” category, but I have seen that Logos Software is selling preorders on an electronic version of the OLD:
Sorry “edonnelly” - missed your post as I haven’t been near the computer much for the past 2 weeks. Yes, I’d love to have the dictionery but at about $200 Australian it might be a bit expensive! But it sounds great!
