arXiv created a Systems and Control category eess.SY that will merge with cs.SY. We also merged the existing Numerical Analysis categories math.NA/cs.NA

Two changes to arXiv categories were made today.

The category for Systems and Control is making the move from computer science to electrical engineering and systems science, where it is a better fit. Users can still submit and search for cs.SY, however the canonical display will be eess.SY. The full description for Systems and Control eess.SY is at https://arxiv.org/archive/eess.

arXiv is also merging the math and computer science categories for Numerical Analysis. The category description is: Numerical algorithms for problems in analysis and algebra, scientific computation. The merge will setup math.NA to be the canonical category for cs.NA.

Thank you to arXiv moderators, subject advisory committees, and scientific advisory board members who provided leadership and input on these changes. Special thanks to our math.NA and cs.NA moderators for putting in extra effort over the past two month to pilot this move.

arXiv looks to the future with move to Cornell CIS

We are pleased to announce that arXiv will move from the Cornell University Library (CUL) to Cornell Computing and Information Science (CIS) in January 2019. As far as researchers and arXiv users are concerned, the stewardship transition will be seamless and unnoticeable. Although the arXiv team is currently housed at the Library, the operation is independent of the Library's organizational, technical, and financial infrastructure. We have decided that CIS is better positioned to move arXiv forward into the next phase of the service's development after a careful assessment process. See press release and transition FAQ for more information.

DONATE to arXiv

arXiv will run an online fundraising campaign for one week, from February 26 to March 4, 2017, to help raise additional funds (see Donations to arXiv. The baseline maintenance costs are sponsored by the 206 member organizations, the Simons Foundation, and Cornell University Library. This online campaign aims to garner additional resources from the program's active and supportive user base.

Stewardship of resources such as arXiv involves not only covering the operational costs but also continuing to enhance their value based on the needs of the user community and the evolving patterns and modes of scholarly communication. It is essential to raise additional funds in order to fund new initiatives that are beyond the routine operational work, and to robustly support arXiv's Open Access mission. Donations to arXiv are tax deductible, eligible for employer matches, and easy to schedule. Donations can be made here. We thank you for your support.

Attention Submitters: Submission Freeze Time is Changing

Beginning January 2, 2017, the freeze time will change to 14:00 US Eastern time (EST/EDT).

The freeze time is the daily submission deadline. As of January 2, 2017, submissions received before 14:00 EST will be scheduled for the forthcoming announcement (usually the same day) and submissions received after 14:00 EST will be scheduled for the subsequent announcement. The reason for this change is the rising number of daily submissions and the need to give volunteer moderators and administrator staff time to complete their work.

Submissions to arXiv are normally announced Sunday - Thursday, with no announcments Friday - Saturday.

23 Feb 2012

American Physical Society and Australian mirrors discontinued: We are reducing the size of the arXiv mirror network to better focus available administrative effort. It is our goal to keep a handful of mirrors with wide geographic spread to help with network outage and disaster tolerance. However, current internet topology means that mirrors are no longer an effective way to improve arXiv access.

The American Physical Society mirror (aps.arXiv.org) has been discontinued. We are grateful for the longstanding and continuing support of the APS, and for help at critical junctures including using the mirror as primary backup during the fires that threatened Los Alamos in 2000.

The Australian mirror (au.arXiv.org) has been discontinued. We thank the CSSM at the University of Adelaide and the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP) for their support of arXiv.

New Submission System: We are pleased to announce that arXiv has a new submission system. We hope that this will improve the submission process for users and streamline administrative operations to help us keep pace with the ever increasing submission rate.

Note that with the new submission system permanent identifiers are assigned only at the time articles are publicly announced. Submitters may edit, delay or remove submissions up until that point but this may affect the announcement order. Those interested in the announcement order should be aware that policies have changes such that:

An update before announcement will reset any article's position in the queue. Announcement order is based on the last "Submit" action.

An update after 16:00 EST/EDT will delay an article to the next day.

4 Mar 2010

Scheduled outage 5 Mar: The arXiv submission system will be disabled at 16:00 EST Fri, 5 Mar 2010 to allow software and hardware changes. The submission system and other facilities requiring login are expected to remain down for a few hours. Browsing will be supported at the main site for most of this time, and on our mirrors throughout.

Delayed announcements 8 Mar: On Mon, 8 Mar 2010 we will delay the publication of new listings and the mailing of email alerts for new submissions from 20:00 EST to approximately 22:00 EST to allow software upgrades to be tested.

Jul 2009

9 Jul 2009

No new papers or announcements for 9 Jul 2009. arXiv administrators spent much of 8 Jul recovering from a problem with the main server (a corrupted database caused by human error on the evening of 7 Jul). During this time users were redirected to mirrors and submissions were not possible. We have thus deferred announcements of new submissions according to the following schedule:

Articles received from 16:00 EDT Tue 7 Jul 2009 through 16:00 EDT Thu 9 Jul 2009 will be announced at 20:00 EDT Thu 9 Jul 2009.

8 Apr 2009

Public author identifiers have been introduced. If you are an author of articles on arXiv, you may opt-in to create a public author identifier which supports interaction with Facebook, a myarticles widget to allow dynamic inclusion of a list of your articles in web pages, and provides HTML and Atom feeds of your arXiv papers.

Mar 2009

31 Mar 2009

A new Quantum Gases (cond-mat.quant-gas) subject area has been added:

cond-mat.quant-gas - Quantum Gases

Ultracold atomic and molecular gases, Bose-Einstein condensation, Feshbach resonances, spinor condensates, optical lattices, quantum simulation with cold atoms and molecules, macroscopic interference phenomena

For more information, see the complete list of cond-mat subcategory descriptions. To subscribe to the daily e-mail notifications for cond-mat.quant-gas or a set of subcategories of cond-mat, you should first cancel your existing subscription, and then subscribe only to the subcategories of interest via physics.

By popular request, the Astrophysics (astro-ph) archive has been split into six subcategories:

astro-ph.CO - Cosmology and Extragalactic Astrophysics

- Cosmology and Extragalactic Astrophysics astro-ph.EP - Earth and Planetary Astrophysics

- Earth and Planetary Astrophysics astro-ph.GA - Galaxy Astrophysics

- Galaxy Astrophysics astro-ph.HE - High Energy Astrophysical Phenomena

- High Energy Astrophysical Phenomena astro-ph.IM - Instrumentation and Methods for Astrophysics

- Instrumentation and Methods for Astrophysics astro-ph.SR - Solar and Stellar Astrophysics

For more information, see the subcategory descriptions (including links to subdivided new and recent listings). This split should make announcements of new papers more manageable for those interested only in subsets of astro-ph. New astro-ph submissions must be assigned one or more subcategories. (Existing astro-ph articles will be machine-classified according to the new scheme when enough training data has been collected.)

To subscribe to the daily e-mail notifications for only a set of subcategories, you should first cancel your existing subscription (either to astro-ph or physics), and then subscribe only to the subcategories of interest via physics.

Dec 2008

4 Dec 2008

A new "Quantitative Finance" (q-fin) archive has been launched. For more information, see the announcement. It is partitioned into 7 subject categories and e-mail subscriptions can be made to any combination of subject categories. It has been "preseeded" with roughly 1700 relevant cross-listings and reclassification of articles from existing subject categories.

arXiv passes half-million article milestone: The 262 new submissions received between Wednesday 1 Oct and Thursday 2 Oct, announced Friday 3 Oct 2008, brought the total number of articles on arXiv past 500,000 -- all openly accessible. There are also more than 200,000 old versions of articles which record all public revisions since 1997. If the linear increase in submission rate continues, arXiv will pass the one million article mark in 2015. See press release for more details.

Jun 2008

26 Jun 2008

June 1997

30 Jun

Frequent complaints re multipart and gzipped files, see nota bene (link removed).

30 Jun

Added information on the latest postscript drivers for Macintosh. These eliminate junk from the Macintosh postscript output. See the psjunk FAQ for details.

30 Jun

Added a user-supplied .com file for automatically viewing compressed postscript on VMS (link removed).

Russia users: note the new mirror in Moscow, xxx.itep.ru, at the Institute for Theoretical and Experimental Physics.

Japan users: note the new upgraded mirror in Kyoto, xxx.yukawa.kyoto-u.ac.jp, at the Yukawa Institute for Theoretical Physics. New papers arrive by 13:45 JST (within 1 hour of availability at LANL).

15 May

Minor change in policy (affects only weekend submissions): the deadline for submissions to appear in the Sunday night mailing is moved back to Friday 18:00 LANL time (currently 00:00 GMT). Submissions received during the rest of the weekend will appear with Monday submissions in the Monday night mailing. After consultation with a large segment of the relevant community, it was determined to continue to delay the announcements of papers received on Fridays until Sunday nights (Monday mornings in Europe), rather than shift the Sunday mailing to Friday night. In a related development, responses to any queries received during the weekend may also be deferred until Monday morning (9:00 LANL time = 1500 GMT) -- Note that 99.97% of all e-mail queries are already answered in our comprehensive on-line help pages and frequently asked questions) section. Recall also that any replacements received after the 18:00 LANL time deadline Mon-Fri constitute a new (revised) version. Please note that whether or not your submission makes the deadline on any given weekday is unlikely to alter markedly the future evolution of the cosmos.

11 May

Spain users, there is now a mirror site at the Universidad de Zaragoza, Spain, xxx.unizar.es. Other users see our existing list of mirror sites.

In order to facilitate feeding the european mirrors each night before the transatlantic links become congested, daily mailings and update of the web interface will now commence at 22:00 U.S. Mountain time Sunday through Thursday (currently 04:00 GMT Monday through Friday), i.e. two hours earlier. The deadline for submissions remains 18:00 US Mountain time (i.e., currently 00:00 GMT, and 01:00 GMT during the winter) Sunday through Thursday.

5 Oct

e-mail subscribers to the physics archives: note that by subscribing to the corresponding subject classes of the new "physics" archive, you have the option to receive a single combined daily mailing (e.g. hep-th, gr-qc, and cond-mat). The option to receive separate mailings will of course remain. For further instructions, e-mail To: [email protected], Subject: subscribe

For general information on the new physics archive (partitioned by keyword subject classification), see http://xxx.lanl.gov/new/

24 Sep

Experimental mirror sites are now operating in France, http://xxx.lpthe.jussieu.fr/ (Paris VI) and the U.K., http://xxx.soton.ac.uk/ (Southampton) joining the existing mirrors in Germany ( http://physinfo.uni-augsburg.de/) and Italy ( http://babbage.sissa.it/) and Japan ( xxx.yukawa.kyoto-u.ac.jp). The latter two will soon be upgraded, and additional mirror sites are anticipated within the next few months. The goal is a more robust global server system (to avoid relapse to the medieval days when hardcopy took days, weeks, or months to arrive...).

24 Sep

On 1 Oct '96, a new "physics" archive will go on-line, and is intended to facilitate growth into areas not currently covered. Submissions will be required to have a Subj-class: field that will effectively keyword partition the archive (for subscriptions, listings, and searches). Existing archives will for the most part remain unaffected. A very provisional list of canonical subject-classes be found at http://xxx.lanl.gov/new/physics , and can be modified as needed. Constructive suggestions solicited.

2 Sep

nlin-sys archives (adap-org chao-dyn comp-gas patt-sol solv-int) consolidated from xyz.lanl.gov to xxx.lanl.gov.

August 1996

4 Aug

Minor policy change: the deadline for submissions to appear in the daily mailings has been moved six hours earlier to 18:00 US Mountain time (i.e., currently 00:00 GMT, and 01:00 GMT during the winter) Sunday through Thursday. The mailings will continue to commence (and web interface updated) shortly after midnight on those days (i.e., currently 06:00 GMT Mon-Fri, and 07:00 GMT during winter). Those few submissions received between 18:00 and midnight mountain time will appear in the next day's mailing. For the most part, this change will be invisible (and will primarily affect late night submissions from the US east coast, sparing us all the 2 a.m. typos...).

(See also messages from 1994-1996 and 1991-1994.)
