 MTS Workshop Proceedings

In May 2014 Don Boettner made his hardcopy collection of proceedings from the 18 workshops held from 1974 to 1993 available. By late June 2014 scanned and OCRed versions of the table of contents materials (schedules, list of papers, list of attendees) were available online as PDFs for viewing or download. And earlier today scanned and OCRed versions for all 18 of the full proceedings (papers and session summaries) were completed and made available online (roughly 13,700 pages in all). Links to the PDFs are available from the "Documents section" of the MTS Archive site (this site). The physical paper copies are destined for the U-M's Bentley Historical Library. I would like to thank Don for saving the proceedings and for making them available.

Don also had a copy of Kari Gluski's trip report for the Community Workshop held in 1994 in Edinburgh. 1994 was the last year a workshop was held. We don't have proceedings for the 1994 workshop and we aren't entirely sure that proceedings were produced. If anyone remembers more details about the 1994 workshop or has a copy of any proceedings, please let us know by sending a note to mts-comments@umich.edu.

I hope to gather more information about the "western workshops" and include that in the MTS Arcive site. I'd welcome any materials or recollections that people may have about these workshops.

I also hope to produce a combined index to the papers and session summaries for all of the workshops, but I'm not sure how long that will take to complete.

There is an MTS Workshops item in the discussion section of this web site that is being used to gather information about the workshops.
