Editing with ebooks
A good way to work around this limitation is to use the eliterature converter to make your ebooks and keep a copy of the original text (txt) file to copy and paste from.
When reading an ebook formatted for Plucker, bookmark a search term and use this to search in the corresponding text file for the text you want to copy and paste.
Use sunrise to send your html files to Plucker on you palm, and Documents to Go to send your text files.
Shortly I will make available a new version of the converter for Gutenberg texts, which can make both html files for Plucker and text files without manual line break. These are more favorably presented on your palm without unnecessary white space.
This approach is preferable to dowloading already formatted texts which can only be read in specific applications and cannot be edited.
Using the eliterature formatter with original Gutenberg texts, you keep maximum control over you texts and independence.
One other advantage of etexts over paper books occurred to me. You can read them in the dark. Ideal for insomniacs who share a bed, or for those who like to read outside at night.
