Frequently Asked Questions

0. The essentials.
The proceedings of STACS are now electronic and freely accessible. They will be accessible through a variety of gateways, among which stacs-conf.org, HAL, and Dagstuhl's DROPS. The sites HAL and DROPS are managed by academic institutions, they guarantee permanent conservation of, and access to, the proceedings. They also guarantee indexing in DBLP and Google Scholar.
1. How is the scholarly quality of the conference upheld now that the proceedings are electronic?
Nothing is changed in this regard, that is, the acceptance process for papers submitted to the conference is not modified. A Program Committee (PC) is named each year by the Steering Committee. Each paper is examined by three PC members at least, possibly with the help of subreferees.
2. Accessing and using papers published in the proceedings of STACS
2.1. How do I access a paper published in the proceedings of STACS?
The proceedings of the STACS conferences from 2008 on are available on www.stacs-conf.org. They are also accessible on the open access repositories HAL and the Dagstuhl publication server DROPS. They are published by the Leibniz Center for Informatics in the open access series Leibniz International Proceedings in Informatics (LIPIcs). Authors may allow or disallow publication of an accepted paper to arXiv (note that publication of a latex generated file to arXiv requires the latex source to be made available).
All STACS proceedings are also indexed by LEABib and by DBLP. From 1984 until 2007, they were published by Springer, in the LNCS series.
2.2. What can I do with a paper published in the electronic proceedings of STACS?
You can read it, online or offline. You can use it: quote parts of it, add it to a course pack, an anthology or a web site. You can print it and give it to colleagues and students. The only constraint is that you must credit the original author and source; see the license and question 2.4.
2.3. Who has the copyright?
The copyright is retained by the author(s). They are requested to sign a license agreement making the uses mentioned in question 2.2 legal. As an example, here is the copyright form that was used for STACS 2008.
2.4. How do I cite a paper published in the proceedings of STACS?
The proper way of citing the paper "This is the long title", written by "A. Uthors", published in the proceedings of STACS yyyy (say, yyyy = 2008) is in the following form:
	      A. Uthors. This is the long title, 
	      in Proceedings of STACS yyyy  
	      (Ed One, Ed Two eds.), reference.
              Available from http://stacs-conf.org.
where reference is either the oai number or the urn provided with the paper on www.stacs-conf.org, HAL, DROPS, and, upon agreement of the authors, on arXiv. See question 3.1. Examples of such identifiers are:
2.5. Are there any charges for the authors or the readers and users?
The electronic proceedings are entirely open-access: access is free, under a Creative Commons License, and there are no page charges for authors or readers. A printed volume of the proceedings may be proposed to the participants of the conference, at an additional fee requested during registration.
2.6. Can I change or resubmit a paper published in the proceedings of STACS?
Passing to electronic proceedings does not change anything in this respect: a paper accepted at STACS and published in the proceedings is an official publication and may not be changed or published again in the same form.
3. Electronic publishing of the proceedings.
3.1. How does the electronic publishing of the proceedings work?
The papers accepted at STACS are uploaded by the Program Committee chairs onto the open access repository HAL, which is managed by the main agencies for public research in France, and onto the Dagstuhl online publication server DROPS. HAL is located in France, DROPS is located in Germany, but both are freely accessible by anyone and from anywhere. In addition, if authors permit it, papers are also deposited on the CoRR (Computing Research Repository), a part of arXiv, established under the auspices of the ACM and Cornell University.

The different volumes of STACS Proceedings, corresponding to the different years, are made available as separate pages on the stacs-conf.org site. They are also constituted as overlays of HAL and DROPS.
Each paper deposited in HAL, arXiv and DROPS receives a unique and permanent URL, as well as a unique identifier which can be used to view the paper and to cite it (see question 2.4). The identifiers attributed by HAL and arXiv conform to the OAI standard (Open Archives Initiative) and those attributed by DROPS to the URN standard (Universal Resource Names). In both cases, identifiers are persistent throughout time and space; they remain fixed, even though the object's web page may change.
3.2. What are open access repositories?
An open access repository is a site, managed by an established academic or scientific institution, on which authors can deposit their publications to make them widely and freely available. The repository expects the papers deposited in it to conform to academic usage and quality, but it does not provide an evaluation of these papers.
STACS relies on an open access repository, namely HAL, which is managed by the main agencies for public research in France; and on the Dagstuhl online publication server DROPS. In addition, upon agreement of the authors, papers are also deposited on the CoRR (Computing Research Repository), a part of arXiv, established under the auspices of the ACM and Cornell University.
3.3. How quickly are papers published?
The set of papers accepted at a given STACS conference will be published electronically ideally in the very last days before the start of the conference. They will definitely be available on the first day of the conference.
3.4. How permanent are these electronic proceedings?
The proceedings volumes are published as overlays of well-established open access repositories: DROPS and HAL. These repositories are managed by stable institutions, in close connection with the research and academic community, and their aim is to guarantee that archived articles are available forever, independent of software development.
3.5. Is there a hardcopy?
A hardcopy of the proceedings may be made available for the conference participants, possibly at an extra fee. It is not planned to print it in much larger quantities than required by the conference attendance.
3.6. Is there an ISBN?
The hardcopy of the proceedings made available to the participants to the conference will have an ISBN, which can be found on the DROPS server (see the online publications for the URLs).
3.7. Are the electronic proceedings indexed by bibliographical bases?
Yes, the repositories HAL and DROPS guarantee in particular indexing in DBLP and Google Scholar. The proceedings of STACS 2008 are being indexed by EI (Engineering Index).
