27th International Meeting of Collectors and Researchers
|when & where||
Due to the COVID pandemic the IM2021 cannot be held as a
classical physical conference, but will be held as
teleconference via the Internet on
We will use the Zoom system.
This web site https://www.im2021.org
was set up to provide you with all necessary information
about the conference.
It has been enhanced with some more details, in particular
the theme, the call for papers, and the schedule.
More will follow later, like the way we intend to handle
the distribution of proceedings to you.
Right now we need you: (a) express your intention to participate to help our planning, (b) your feedback on the theme, and (c) papers!

This year's motto / theme will be
Presentations and discussions at IMs tend to be object centric. Participants are generally interested in details of specific slide rules / instruments, their scales, construction details, mathematical, technological or application background, and more the like. We certainly will have many of such contributions this time again; actually the majority of IM talks traditionally is of this nature. So, if you have a contribution of that kind, you are most welcome, and we urge you to submit a paper and give a talk!
But next to that we propose a session or two about the process of collecting and researching such items. There are many aspects to that, often of very practical nature, and many of these are generally not well documented. Many of these like cleaning, repairing, preserving, storing, documenting, catalogueing slide rules or other instruments are more or less independent of the current situation, excecpt that we might have more time for these activities while we are at home in lockdown or even quarantine. Each of these activities deserves to be a subject of this IM; just two examples: (a) making really good photos of slide rules, which is harder than it seems at first glance, and (b) making and maintaining a proper inventory / catalogue of your collection.
Other aspects are heavily affected by the limits imposed on us by the pandemic, like the acquisition of items, as we do not have personal meetings, antique shops are closed, there are not live auctions, nor flee markets, nor boot or garage sales. Research became difficult, as libraries and archives are closed, and travel became restricted or even impossible. For these and other aspects we would like to have talks, papers and discussions about your experiences, both your happy moments before COVID-19 and now, using electronic communication like this teleconference. How much changed the Internet the collection of things like slide rules, (mechanical) calculators, and other mathematical instruments?
And then is one final issue, after collecting, the disposal of a collection. Degrading health with the inability to take care of a collection and ultimately death were always with us. A pandemic like COVID-19 significantly raised the probability of a sudden stop of our active life. Nearly all of the IM participants have private collections, not institutional ones where other people will take care of things in the future. So, what kind of arrangements have we made? What will happen to our collections? What are the items to preserve to posterity, what about the others? What about literature and often unique documents? What about electronic records on our computers and what about our web sites? It's not an easy subject, both with respect to practicality and even more so for our conscience. Nevertheless we should avoid avoiding the subject, COVID is here. Please contact the IM organizer and editor with your ideas on how we address the subject at the conference; he will be even more pleased to get some papers and presentations on this issue.

The conference proceedings will be published as a book in the same style and manner as IM2013 and IM2017. Details will follow later, in particular about its distribution to participants. We intent to have the proceedings ready and in your hands in time for the conference.
In order to get everything ready in time, please notify us (email@example.com) as soon as possible, if you intend to make a presentation, and please submit your paper as early as possible.
16.05.2021 deadline for the submission
of your paper

Furthermore we ask you to notify us ASAP by an email to firstname.lastname@example.org with your name, location/country and email address if you intend (no obligation) to participate. This will help us to get a feel for the number of probable participants for the planning and organization of the conference, and will help sending out reminders for the your formal registration, which will come later. So even if you are undecided or perhaps unsure if nearer the day you may have conflicting commitments, please at least indicate your interest with an email.
The International Meeting is a yearly event for
collectors and researchers of slide rules and
other mathematical instruments.
The 2021 meeting will be the 27th in this series.
The IM is traditionally
organized by volunteers from the four national
RST from Germany / German speaking countries,
KRING from The Netherlands,
UKSRC from the United Kingdom, and the
Oughtred Society mainly from the USA
(although the OS is an international society)
on a rotational basis.
The style of our meetings is informal and non-profit,
in the best tradition of both amateurs in the classical sense
and serious researchers.
More about the IM series of conferences is available on our IM history web page.
