Computability (the journal of the association CiE) invites submission of full papers of highest quality on all research topics related to computability. Computability accepts only submissions of original research papers that have not been published previously and that are not currently submitted elsewhere. Full versions of papers that have already been published in conference proceedings are eligible only if the conference version is clearly cited and the full version enhances the conference version significantly. Authors are requested to submit PDF manuscripts electronically via this online submission system. Authors can indicate non-binding wishes regarding Editorial Board Members who should handle their submission (please indicate this in the "Cover Letter" below). Final versions of accepted papers have to be prepared using the journal style file and they need to be submitted together with all source files. Authors submitting a manuscript do so on the understanding that they have read and agreed to the terms of the IOS Press Author Copyright Agreement and that all persons listed as authors have given their approval for the submission of the paper. To submit a manuscript, fill in the following form and click the Submit button. The manuscript file should not be open on your desktop. All tables, figures and other graphics should be contained within the manuscript itself. Please use the form below also for the re-submission of a revised version of a paper and mention the manuscript number and the fact that this is a re-submission in the cover letter.
