The MTA is looking for volunteers to help making all articles from M Computing available "on the web".
It is possible to use scanning techniques to make old articles available, or to re-type the texts from the published journals. We have learned that the scanning software is getting better at every release, but is still not flawless. The effort of re-typing an article would depend on the typing skills of the volunteer, and we have learned the hard wat that the effort of correcting typos (scan-o's?) in a scanned page takes only slightly less time than retyping...
If you are interested in volunteering to help making more articles available on the web, please e-mail Kate Schell.
