Manybooks.net

Manybooks.net has all the Gutenberg texts available in various formats for most mobile devices. This is the place to get Gutenberg texts which do not need to be converted at all. Thanks to Dick Tracy at Mobile Read Networks for the tip.

MobileRead Networks
MobileRead Networks is a forum for people who use mobile ebooks. I read there about how to cut and paste from a plucker document on a Palm. Use View > Export to Memo which saves the current screen as a memo.
Depending on your needs this would be a simpler procedure than converting both an html and a text version of a Gutenberg text when just a short piece of text needs to be quoted (as suggested in a previous entry).
