News From ACM



ACM released its 2012 Academic Consortium Pricing early this week. Consistent with ACM's educational and scientific mission to provide high quality information resources to the scholarly community at an affordable price, ACM's average price increase for 2012 is once again in the 3-4% range for the vast majority of ACM's subscribers. Many institutions are feeling the pinch during these difficult economic times and ACM is making every effort to ease the burden on our subscribers by keeping price increases low, despite adding new titles and content, and continuing to innovate with several exciting new features and functionality for the DL platform in 2011 & 2012.

One of the main themes for 2012 is making sure institutions continue to get good value out of the DL. Whether that means providing the resource to a small but vital department with only a handful of faculty and students who need access to a select list of ACM publications and access to the complete Guide to Computing Literature or to a large department with hundreds of students and faculty members who are making significant daily use out of all ACM and affiliated publications, it is important that each institution appreciates the value they are getting out of the ACM DL. One way to assess this value is by examining usage. Over the past few months, ACM has been carefully evaluating the number of full-text downloads and searches conducted across the DL platform. This is the first time such a comprehensive analysis has been done in the age of COUNTER statistics, which provide us some assurance that we are comparing apples to apples across the nearly 3,000 institutions who regularly access the DL from around the world. What we have learned is that while some institutions are downloading hundreds of important articles each year from the DL, there are those who are now downloading tens of thousands. Many of our smaller subscribers get excellent value out of the DL, but their usage tends to remain relatively flat from year to year, while for the largest research institutions usage continues to grow at rapidly increasing rates. This growing disparity between those select "heavy users" within ACM's usage-based tier structure has highlighted the need for us to make some incremental changes to the tier structure itself.

As from January 1, 2012, ACM has modified its existing 5 Tier structure and added two new tiers on the high end. The following is the existing tier structure prior to the change:

2011 Usage-Based Tiering

Tiers# Full Text Downloads
Tier 12 Year Institutions (usage not evaluated)
Tier 20 - 400
Tier 3401 - 1,700
Tier 41,701 - 5,400
Tier 55,401+

Going forward, the following structure will apply:

2012 Usage-Based Tiering

ACM TiersUnited States Pricing International Pricing
Carnegie ClassificationUsageUsage
Tier 11 -14n/a2 Year Colleges
Tier 221 - 33n/a0 - 400
Tier 318 - 20n/a401 - 1,700
Tier 416 & 17n/a1,701 - 5,400
Tier 515n/a5,401 - 10,000
Tier 6Usage Based 10,001 - 25,00010,001 - 25,000
Tier 7Usage Based25,001+25,000+

The main change is the division of Tier 5 into three new tiers (5-7), which provides some additional granularity on usage. There is no change to the usage bands for Tiers 1-4 and no financial impact whatsoever for subscribers in these tiers, other than that these subscribers will receive a slightly lower rate of increase in pricing for 2012 and subsequent years to start to address the disparity in pricing with the largest tiers.

For a variety of reasons, we believe this approach is the fairest possible way of addressing the usage and pricing disparity between our smallest institutions and the heaviest users of our resources. Price increases for all tiers remains well within what is generally accepted by the market, and overall ACM continues to be one of the best value-for-money publishers in the industry today with the least aggressive increases in the academic market. The following chart highlights the 2012 pricing, including percentage (%) increases over 2011 list prices.

Tiers2012 Academic List Prices (US$)

% increase
from 2011-2012

Tier 1 $2,0000%
Tier 2$13,6892%
Tier 3$15,0733%
Tier 4$15,9354%
Tier 5$16,8225%
Tier 6$17,1427% over Tier 5
Tier 7$17,4629% over Tier 5

* Discounts based on ACM consortium discount policy, but typically range between 40-60%

Whether you are a renewing institution or a potential new subscriber, when evaluating these prices, please keep the following in mind:
  1. 2011 Pricing for Academic institutions remains valid for all orders that are placed and have a subscription start date prior to January 1, 2012.
  2. All orders placed on or after January 1, 2012 will receive the new 2012 pricing.
  3. 2012 Academic List Pricing is valid for all institutions ordering directly through ACM.
  4. Volume-based discounts are available for institutions ordering directly through academic library consortium. This accounts for the overwhelming majority (94%+) of our subscribing institutions. Please see below for more details.
Academic consortium pricing is determined by several factors, including:
  • Annual List Prices
  • Number of Participating Members in the Consortium
  • Economic Discounts based on 2011 World Bank List of Economies
  • Carnegie Classifications and Usage for U.S.-based academic institutions
  • Usage for International-based academic institutions
Additional information regarding the new tiers and pricing for 2012 is posted on our library website at Please do not hesitate to contact us at with any questions you have related to the above information. Thank you.

ACM TECOM[sic] [Should be TEAC] is a new interdisciplinary journal at the intersection of economics and computer science. The past decade has seen a surge of research driven both by necessity and opportunity. As computer systems become more inter-connected, multiple parties must interact in the same environment and compete for scarce resources which necessarily introduce economic phenomena. And in the past, economic mechanisms (such as auctions and exchanges) have been designed to require very limited computing and communication resources, as they would otherwise be impractical. These days, computation and communication pose much less of a constraint, which presents an opportunity to create highly efficient, computationally intensive mechanisms.

ACM TECOM[sic] [Should be TEAC] is led by two distinguished co-EICs, Vincent Conitzer, Assistant Professor of Computer Science and Economics at Duke University, and Preston McAfee, economist, VP and Research Fellow at Yahoo! Research.

Those institutions using Athens or Shibboleth to track their individual patrons’ use of resources, may now be authenticated via these systems for use of the ACM Digital Library.

When a user comes to the ACM DL from an institution that uses one of these two systems (and if ACM has enabled Athens or Shibboleth login for that institution), that user can log in to the DL with the Athens or Shibboleth ID whether or not their institution is already IP-authenticated with ACM.

The individual’s login is tied to their institution and all activity is recorded and attributed to his/her institution.

For those end users who also have ACM web accounts, they can login under their institution’s IP authentication with their ACM web account or under their Athens/Shibboleth account. These two accounts are not tied together right now. So binders created under one will not be joined with binders created under the other. Institutional activity will be properly credited, but individual activity will be split.

The ACM Digital Library eCommerce functions will work with an individual’s Athens or Shibboleth login; they do not require that individual’s ACM web account.

ACM is already a member of Athens and belongs to the largest Shibboleth Federation – the one in the UK with 600 members including affiliated institutions in the Far East (and elsewhere).

Once an institution officially notifies ACM that they wish their patrons to be authenticated via Athens, ACM will enable them. For Shibboleth the same is true UNLESS the institution belongs to one of the other 8 non-UK federations. Then a) that institution must RECOMMEND ACM to the Federation and b) ACM must file and be accepted.

ORCID (Open Researcher and Contributor ID) now has 240 participating organizations from 36 different countries. ORCID incorporated as a not-for-profit in August 2011 with the mission to solve the contributor name ambiguity and resultant attribution problems in scholarly communications by establishing an independent central registry of unique person-identifiers for researchers. ORCID recognizes the existence of other identification systems, some proprietary and others open, and will interact compatibly with these systems. Examples include Author Resolver, InSPIRE, PubMed ID, RePEc, ResearcherID, Scopus Identifier, and VIVO, among others.

By associating unique identifiers with researchers across the world, the process of scientific discovery, impact tracking and the efficiency of research funding and collaboration will be significantly enhanced for all the stakeholders in research – from funders, to publishers, to governments and to researchers.

The ORCID Board of Directors has been selected from 14 organizations from the global scholarly research community; it includes funders, professional societies, universities, and publishers. The ORCID Bylaws require a majority of members from non-profit organizations (10 at present). ORCID is committed to the openness embodied in its ten ORCID Principles which may be found at

ACM sits on the ORCID Board of Directors. ORCID is currently completing the technical specifications of a two-phase development and plans to begin delivering Phase 1 services to the community in early part of 2012. ORCID’s first sponsorship drive raised $250,000. A necessary second drive is underway to reach production goal.
