1) What is the GDEA?
The GDEA seeks to be the main repository for publications on Graph Drawing. The GDEA will provide easy access to deposited materials for users, and serves as a permanent archive for their retention. The server is used by academics, researchers, and students. Normally an author used to prepare multiple copies of a new manuscript and mail it to the community for their information and for response. As a registered member of the GDEA an author submits his documents to this archive. The advantages of this service:

- Greater circulation can be achieved by deposting on the GDEA at no cost to the author.

- A subscription service gives the possibility to receive regular email updates of papers deposited to the archive in areas of interest every day, week or month.

2) What is the subject area of materials on the GDEA?
Materials must deal with some aspect of the topic of Graph Drawing.

3) Who can submit materials to the GDEA?
Anyone can submit materials to the GDEA; there are no formal restrictions. However, all persons submitting materials must register and materials submitted must meet certain academic requirements. For registration send an email to with the following information:

Given and Family Name, Organisation, Adress, and the Email address

The Archive staff will then create your account and email the details to you.

4) Will posting on the GDEA affect subsequent attempts to publish in a journal?
This is a matter for the individual journals to decide. Our impression is that these policies are in flux with the trend towards greater tolerance. Take a look to the strong precedent of the physicists' enormous LANL archive. Papers posted there routinely proceed to refereed journals.

5) If I post a preprint on the GDEA and then publish it in a journal or volume, can I leave the preprint on the GDEA?
Individual journal policies vary on this question. Whatever the policy, the authoritative document is the copyright agreement you sign with the publisher. If that agreement requires you to remove the deposited preprint, you should. Not all agreements require this. For example the current copyright agreement used by Elsevier for the journals:

"...Posting of a preprint version of this work on an electronic public server is permitted. Posting of the published article on a secure network (not accessible to the public) within the author's institution is permitted. However, posting of the published article on an electronic public server can only be done with Elsevier's written permission."

6) May we submit material to the archive that has appeared elsewhere?
The GDEA does not require or expect that material has not appeared elsewhere. However, if it has appeared elsewhere, the author must determine whether copyright was transferred from the author and whether the copyright agreement allows posting on the GDEA. While the GDEA does not object to duplication, the other source may.

7) Can I remove a title once it is posted?
Yes. Papers can be removed. Unfortunately the ePrint software does not allow you to remove papers automatically. Removal is initiated with a removal request, accessible through the links "Deposit Papers" --> "Review your documents in the archive". Archive staff will then remove the paper as quickly as possible. All requests for removal will be honored, although we encourage you to leave preprints posted for stability of the archive's contents.

8) Do the GDEA accept non-English submissions?
The GDEA accepts papers in any language. However, abstract must be in English.

9) Will the GDEA editorial staff revise or edit submitted materials?
The GDEA staff check only the Metadata (like title, abstract etc) with regard to the right spelling. Under no conditions will the staff make any changes or revisions to contents submitted. Contents will be either accepted or rejected as submitted.

10) Are there any quality control checks?
Incoming submissions do not go straight into the archive; initially they are placed in a "buffer". The papers in this buffer are then reviewed by the GDEA staff and only those with content suitable for the archive are installed. This prevents the archive becoming clogged up with unsuitable material.

11) Must I register on the GDEA to view or download materials there?
No. You need to register only if you want to deposit materials or if you want to receive regularly scheduled e-mail notification of new submissions to the archive.
