Using HTML would seem to make the most sense, that way you do not need any additional software.

You could even have a wap version so you could put it on a card and use it on your phone.

I have started a Technique and Information Binder myself, so I can have the stuff I want with me, but also change and add to it. The 20 or so books I found myself carrying started to get on my nerves. This way, I can have as many plant id photos as I want, but only of Plants I want to id.

Yes, I know, 20 books sounds a lot but once you consider the 5 plant-ish Id books from collins gem and the survival books and the bushcraft books, it starts to get silly. That is not counting the Medical/Herbal books. The problem I found was the good herbal book has bad or no id pictures, and the good plant id books have little or no herbal information or preparetion information.

I really like this idea.
