Although eBooks are now gaining popularity, they've been around for a long time and in many different formats. Some of those formats are now losing support, and require conversion to current eBook formats for use on the iPad. The IMP format is one of the more challenging systems to convert to a usable formant, but is now possible by extracting the raw text first.
Download and install eBook Publisher from eBook Technologies.
Install a PDF printer driver. Several are available for free online, and are installed as a printer, allowing you to create an Adobe PDF file from almost any document.
Run the eBook Viewer software contained in the eBook Publisher package, and open the IMP-formatted eBook.
Print the IMP eBook using the PDF printer driver, saving the resulting PDF file to your computer.
Load the PDF file into optical character recognition (OCR) software. This will scan the PDF file and extract the text into a raw format such as a TXT file.
Open the text file in Stanza Desktop. Click the "File" menu, then select "Export Book As." Save this using the ePub format.
Drag and drop the ePub-formatted eBook into the iTunes library. Plug in the iPad, go to its "Books" tab and tick the box next to the ePub eBook to sync it to the iPad's iBooks application.
You can also install the Stanza eBook reader application on the iPad, and use the Stanza Desktop software to send eBooks to the device wirelessly. OCR can be performed online using various services, without the need to install any software on your computer.
Formatting can be lost during the OCR process, or when saving as a raw text file.
