The Kindle doesn't support multiple page browsing. The Kindle however does 'save' the last page you visited, which you can read by loading the web browser, which can work offline with that page.
Another way to save a webpage is to email the Amazon conversion tool (firstname.lastname@example.org) which converts it and either sends it to you through wireless or 3G.
Do you mean on the Kindle, or your desktop? I just started to play with that today.
Calibre is a desktop program, which includes tools you can use from the command line if you want.
Yes, that's all a bummer. I'm pleased you can at least open text files and pdfs on it. There are lots of texts on Project Gutenburg that could be used on Kindle, I suppose.
Thanks for your post, Hal9k. Very interesting info.
There is a Oxford and American dictionary included in the Kindle, which I use fairly frequently. It is especially useful for looking up proper names for characters from mythology.
Using various tools you can also get foreign language dictionaries from other websites, such as Mobipocket working on the Kindle. German speakers are also lucky as the entire range of fantastic PONS dictionaries are available. E-Readers will probably kill off those expensive single-function translator devices.
The search function on the Kindle is very fast and is especially handy looking up the names of characters. This is probably true of most E-Readers. The search results can be flipped through and a click of the 'back' button takes you to the point where you were reading. The 'back' button also allows you to read the place in the book where the character first appeared, then easily jump back to the search results, then back to where you were first reading.
