The International Machine Cancel Society -- Electronic Document and Social Media Projects
The Society recognizes that it needs to maintain a presence
in current electronic environments, including social media systems. To
this end, the Society has a
and is experimenting with
a machine cancel discussion group on 'groups.io'.
Of course, the website for the Society remains a central source of information and
documentation regarding machine cancels. The website is now an
extensive source of
from Forum articles to award-winning exhibits.
The website is now facing a major challenge: search engines are ceasing to
scan websites that do not work well with portable devices, such
as phones and tablets. If a web page does not pass muster, it will
not be searchable. The Society has made a major effort to update
web pages for all devices, but many of the older content is still
of the design standards of the year 2000, not of 2020. The effort to
support phones, and to get on the search engines is ongoing.
Electronic Formats for Machine Cancel Documents
Some of the Society resources available on-line have been
converted to portable reader formats, to allow our members
to view the documents on their iPad's, Nook's, Amazon Kindle
(tm) devices, and mobile smart phones.
Currently, most of the Society's documents
are stored on the website in PDF format, which is readable on
some of these devices. Unfortunately, PDF files
are not optimized for reading on many of the
smaller devices, such as smartphones.
The iPad, Nook, and others, ideally read a format called EPUB.
The Kindle can read the propietary "MOBI" (or AZW3) format.
The following links will allow you to download
some of the Machine Cancel Society
documents in formats other than PDF.
For instance, the website has many articles from past issues
of the Machine Cancel Forum. These files are
being updated from
old HTML. It is hoped that they will be more readable on phones and
tablets. For instance, recent work has taken place with the
Milam and Holmes machine history article from the 2007 Forum,
written by A. J. Savakis. The article is now available
in Kindle (AZW3), EPUB, PDF (original), and as a
Many more recent auction listings have been converted
to e-document formats, such as Kindle, web, and EPUB.
Links to these listings can be found on the
items web page. Auctions are listed in
reverse order, the most recent first.

Our members have created a number of award-winning
exhibits. These are available in both PDF format, and
as web-based files. The web-based files can be viewed online
and can be downloaded for offline reading. See:
Machine Cancel Society Award-Winning Exhibits by Members
for links to each of the exhibits.
In particular, note that Mike Ellingson's special 2016 machine cancel
exhibit is available in several formats. See:

Special Editions of The Machine Cancel Forum
We are proud to report that more than one
special edition of the Machine Cancel Forum is available
on our website in multiple formats.
For instance, a special edition of the Forum was generated for
the 2009 APS Stampshow by our Forum editor. Electronic copies of this special edition have
been previously made available as PDF files, including:
the entire Forum as a single PDF file [9 megabytes]
and individual PDF files for each article in the special Forum edition [9 megabytes].
[For information on downloading and reading PDF

and reading and extracting from ZIP files, see

This special edition of the Forum is also available in the "MOBI" format, which
is compatible with the Amazon Kindle (tm), and mobile "smart" phones. Interested Kindle
and phone owners
should try downloading the
Special Edition 2009 Stampshow Machine Cancel Forum [11 megabyte .mobi file].
We have also made this special edition available in the EPUB format at
Special Edition 2009 Stampshow Machine Cancel Forum [1.7 megabyte .epub file].
And that's not all: another special edition of the Forum was created by our very-busy
editor for the Garfield-Perry Show in 2010.
Special Edition Garfield-Perry Machine Cancel Forum.
The Garfield-Perry special edition did not convert well to the MOBI format, so
we have created a special version of
its PDF file that reads quite well on the Kindle (especially
when viewed horizontally).

Military Flag Census
Our webmaster, Bob Swanson, has made available online,
his spreadsheet of the current census of American
Flag Cancels of Military Facilities. This file is stored
on Google Documents, so does not require any
special reader software. It should be readable by any
web browser. The file has a Copyright
statement, but the data is free to use for personal
and research use. The original information for this census
came from Page 61 of the previous edition of the Flag Cancel Encyclopedia by
the late Frederick Langford. Bob maintains this listing of every
reported date, and has enhanced the historical data by adding
more dates and cancellations to the listing
over the years. You can view the spreadsheet at:
