Current Status of the Machine Cancel Society Social Media and Electronic Document Projects

Updated January 28, 2020

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 Facebook Page, 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.

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" format. The following links will allow you to download some of the Machine Cancel Society documents in formats other than PDF.

Articles

The website has many articles from past issues of the Machine Cancel Forum. These files are old HTML, and are not very readable on phones and tablets.

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 webpage.

Auctions

A number of recent auction lot listings are available in electronic formats beyond PDF. Here is an example, an EPUB file of a recent Society Auction. Machine Cancel Society Auction, Closing November 12, 2019 (EPUB).

[For information on downloading and reading EPUB files see this webpage on how to download and view EPUB files.]

For users of Amazon Kindle (tm), the same recent Society Auction listing can be downloaded as a MOBI file, readable on the Kindle device. Machine Cancel Society Auction, Closed November 12, 2019 (AZW3 or MOBI).

[For information on downloading and reading MOBI and AZW3 files see this webpage on how to download and view MOBI and AZW3 files.]

For more information on this auction, see the auction description page.

For information on all Society Auctions, see Machine Cancel Society auction information.

Exhibits

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: Mike Ellingson's Special U. S. Machine Cancel Overview Exhibit from the NYC2016 Show.

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 files see this webpage on how to download and view PDF files, and reading and extracting from ZIP files, see this webpage on how to download and extract from ZIP files.]

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. See: 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). Try: Special Edition Garfield-Perry Machine Cancel Forum ["narrow margin version", 8MB PDF file].

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: spreadsheet with all known usage dates of American flag cancellations of U.S. domestic military facilities of the First World War.
