Workshop: Exploring the Early Digital, Jan 2017

Title: Exploring the Early Digital
Venue: Siegen University, Germany
Dates: January 12-14, 2017
Organizers: Thomas Haigh & Sebastian Gießmann

Following the successful June 2016 workshop “Beyond ENIAC: Early Digital Platforms & Practices” the iSchool of Siegen University is holding a followup event to lay the groundwork for a book with the provisional title Exploring the Early Digital. The book, intended as a reader suitable for classroom use and as an introduction to research in the field, will be a mixture of accessible new work by leading scholars and reprints/excerpts from existing works.

Most of the workshop will therefore be spent reviewing and discussing drafts/position papers circulated in advance by invited contributors to the book. There will also be two public lectures by scholars visiting from the United States, a panel discussion featuring the authors of the most influential overview histories of computing, and sessions spent planning out the content and structure of the book.

The workshop is open to all interested participants. To gain access to the precirculated documents, email

Location: All events will be held in Herrengarten 3, 57072 Siegen. This is in the city center, very close to the main train station and restaurants, rather than in the main university campus.  Unless noted otherwise, all events take place in room 210/11. Scroll to the bottom of this page for maps and logistics.

Format: The authors of drafts will have up to ten minutes to introduce their material. This introduction should give context, flag challenges, and identify areas in which input would be particularly useful. Authors should not try to present their drafts as talks. All participants should have read the drafts prior to the meeting, but one or two are identified as “lead discussants” for each draft. The lead discussants should read with particular care, identify questions for the authors, and be prepared to step in if discussion seems to be fading or moving in an unproductive direction. Lead discussants may speak for up to five minutes each immediately after the initial statements by the author of the draft. Lead discussants should make notes during the session with suggestions and comments based on the discussion and forward these to Thomas Haigh for distribution to the author(s) of the draft.

Logistics. This map shows the pedestrian route to Herrengarten 3 from Siegen train station, a very short walk though the central shopping area. The driving route from the city center motorway exit is also visible.


There are several shopping complexes with large parking garages very close to the venue. The Parkhaus Reichwalds Ecke has been recommended to me as the most convenient place to park (map link).

Getting to the venue from the Ramada hotel is a slightly longer walk – just over 1 kilometer straight down Sandstrasse to the city center.


Sponsors: This workshop is supported by

  • the Siegen University iSchool and
  • the SFB “Media of Cooperation” initiative, as part of project A01: Digitally networked media between specialization and universalization.
