Semantic Scholar Pilot for Computer Science Papers: arXiv is collaborating on a 12-month pilot project with the Allen Institute for Artificial Intelligence (AI2), making the AI-based semanticscholar.org search engine available to the arXiv community.

arXiv exceeds 10,000 submissions for October: Last month was the first time in arXiv history that we exceeded 10,000 new submissions in one month. This milestone was predicted by Paul Ginsparg in 2014 based on historical growth trends and the numbers of weekdays per month. We thank our users for their continued support of arXiv!
Projected and actual submissions ending Oct 31, 2016

We are pleased to share with you the key findings of the arXiv user survey . We were heartened to receive 36,000 responses, representing arXiv's diverse community. We express our deep gratitude to users who provided us with valuable input and thank each of you for making arXiv a part of your scholarship.

DONATE to arXiv: arXiv will run an online fundraising campaign for one week, from June 27 to July 5, 2016, to help raise additional funds (see Donations to arXiv ). The baseline maintenance costs are sponsored by the 190 member organizations, the Simons Foundation, and Cornell University Library. This new GIVE 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. More information about this pilot is available in the arXiv FAQ . We thank you for your support.

Take the arXiv user survey: As an open-access site, arXiv serves people like you all over the world and your opinion counts. Please complete this questionnaire to help us improve arXiv and think of future directions for the service in a way that best serves users like you. The survey has four sections, and will take about 10 minutes to complete. We do not collect any information that can identify you and we will share only a summary of the results. Thank you!

arXiv online fund raising pilot: arXiv will run a brief online fund raising campaign during September 2015 to explore ways to raise additional funds (see donations to arXiv ). As described in arXiv's last annual update , the current business model is working well, sponsoring arXiv's baseline maintenance costs with support from 183 member libraries, the Simons Foundation, and Cornell University Library. This pilot will assess whether a give button placed prominently on arXiv's web pages will 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. More information about this pilot is available in the arXiv FAQ .

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.
