My Thoughts
This chapter has described in great detail the evolution and development of computer typesetting, text formatting and printing. Technology that was once unimaginable has created an industry where vast amounts of documents and information can be stored, searched and retrieved. It is overwhelming to think (and read!) about the amount of technology that has developed to achieve documents available in the digital form that are able to be printed, stored, searched for or are even just viewable! It is hard to think of a time when information was just not available from a desktop and this article has given me an appreciation of all the work that has gone on to create the way documents and information are available digitally.
