New York--R.R. Donnelley & Sons, Chicago, and Microsoft Corp., Redmond, Wash., have partnered to make it easier to read long text documents on computers. Initially aimed at spurring growth of the eBook industry, Donnelley said the effort will reach into catalog publishing, longer corporate marketing materials and corporate communications. Initially, Donnelley plans to produce digital documents based on the Open eBook specification, maintain the digital document repository and distribute books to readers with special reading software from Microsoft. Donnelley said Microsoft technology called Microsoft Reader, which features ClearType font technology, improves resolution of printed words on computer screens--something that's needed to make longer computer text documents more accessible to readers.
