10 Things You Should Know About JSTOR
1. JSTOR is a not-for-profit organization, founded to help academic libraries and p...ublishers.
JSTOR is a shared digital library created in 1995 to help university and college libraries free up space on their shelves, save costs, and provide greater levels of access to more content than ever before. More generally, by digitizing content to high standards and supporting its long-term preservation, we also aim to help libraries and academic publishers transition their activities from print to digital operations. Our aim is to expand access to scholarly content around the world and to preserve it for future generations. We provide access to some or all of the content free of charge when we believe we can do so while still meeting our long-term obligations.
JSTOR currently includes more than 2,000 academic journals, dating back to the first volume ever published, along with thousands of monographs and other materials relevant for education. We have digitized more than 50 million pages and continue to digitize approximately 3 million pages annually. Our activities, our fee structure, and the way we manage the service and its resources reflect our historical commitment to serve colleges and universities as a trusted digital archive, and our responsibility to publishers as stewards of their content. This underlying philosophy at JSTOR remains the core of our service even as we continue to seek ways to expand access to people beyond academic institutions.
2. JSTOR is not a publisher, and we do not ask for exclusive rights to the content on the platform.
We do not hold the copyright to any of the content we make available. We obtain licenses to preserve and make published content available digitally from publishers, most of whom are not-for-profit scholarly societies and university presses. Our ability to provide access to others is dependent of the rights publishers hold and those they provide to us.
Our licenses from publishers are non-exclusive, meaning that the publishers are free to license their content to others to digitize or make it available in any way they might wish.
3. Fees are charged to cover our costs.
JSTOR digitizes millions of pages of scholarly content each year, provides reliable 24/7 access to people in 160+ countries, invests in new technologies to support the use of this content, provides outreach and support for our constituents, pays license fees to content owners, and ensures the preservation of the content over time. We do this with funds provided by thousands of libraries and institutions, all of whom are our partners in disseminating access around the globe.
4. JSTOR offers great economic value for libraries.
Our fee models are designed to provide the broadest possible access to scholarship while also ensuring that access is reliable and that it will be available for future generations. Fees for JSTOR collections have remained unchanged since 1997. There have been no annual or cost of living increases, even though additional content is added each year with the “moving wall”. Fees for access vary based on the type of institution. Research universities contribute much higher fees than small colleges. Community colleges, public libraries and high schools pay much less for access to the same content and service. Many institutions even have free access (see point #6).
5. JSTOR is widely available to walk-in library users.
Every library in our network of more than 8,400 institutions worldwide is authorized to provide access to the content on JSTOR for walk-in users for free. Public libraries, such as Boston Public or the San Francisco Public, may provide off-site access to library card holders. Libraries may also utilize JSTOR for electronic inter-library loan, providing a way for people to gain access even if their local libraries are not among those that participate in JSTOR.
6. JSTOR provides free or low cost access to more than 1,300 institutions in 69 countries.
Nearly 900 institutions in Africa and other developing nations receive access to JSTOR free of charge. An additional 450 institutions in developing nations receive access for steeply reduced fees. This is made possible through a combination of philanthropic support and the fees paid by libraries in other countries around the world, as well as publishers’ eagerness to support this work. More information is available about our African Access Initiative and Developing Nations Access Initiative programs.
7. JSTOR provides free access to hundreds of thousands of articles in the public domain, and our work does not impact the copyright status of this content.
While the majority of journal content preserved by and made available through JSTOR is licensed from publishers, some is in the public domain. In September 2011, we released Early Journal Content, which made nearly 500,000 public domain articles from more than 200 journals freely available to the public on the JSTOR platform. Early Journal Content includes U.S. content published before 1923 and non-U.S. content published prior to 1870.
The public domain content we preserve and make available remains in the public domain. This means that people can freely undertake their own digitization of these works and distribute them in any way they may wish. Google, for example, has digitized and makes available some of the same public domain content also available from JSTOR. People may also redistribute the Early Journal Content files from JSTOR for non-commercial purposes.
We are able to make the Early Journal Content freely available because it is in the public domain and because JSTOR continues to charge fees for access to some content in order to cover costs of providing access to and preserving the entire library for the long-term.
8. Research articles on the JSTOR platform are largely from the social sciences and the humanities, and generally were not “taxpayer funded.”
Some assume that the content included on the JSTOR platform has been funded by taxpayers and therefore should be freely accessible to all. Although there is no way to know how many of the millions of articles published over many years may have received government support in whole or in part, the content on JSTOR comes from a broad range of disciplines, predominantly in the humanities, social sciences, and field sciences. Unlike in the medical and other bench sciences, these disciplines are not generally supported by government research grants. The societies responsible for publishing most of the journals in JSTOR are non-governmental not-for-profit enterprises. Even if the research in these titles had been taxpayer funded, that would not eliminate the costs associated with digitizing the print journals, organizing the digitized content, making it conveniently searchable and accessible on the web, and preserving it for the long-term.
9. JSTOR steadily has made progress expanding access options for individuals.
JSTOR was created as a resource for the academic community, but as digital technology has become more ubiquitous in society, there is increased awareness of and interest in this content from the general public. As early as 1999 we established a program through which more than 110 publishers now provide access to the complete contents of their 350 journals on JSTOR directly to individuals, some as a benefit of society membership and some for a fee.
In 2006, we made arrangements for Google to index the full-text content in JSTOR. This facilitated access for students and faculty using Google for search but also introduced JSTOR to millions of people around the world. The relationships we had established with publishers, libraries and researchers in JSTOR’s first phase did not take into account this new worldwide demand from individuals not affiliated with institutions. We have therefore taken steps, working with publishers that own the content, to meet this new demand.
We established a publisher sales service that enables publishers, at their discretion, to make individual articles available for sale through JSTOR; approximately 850 journals are now part of that program. The price for purchasing individual articles is set by each publisher and includes a flat fee to cover JSTOR’s costs for providing the service.
In March 2012, we launched Register & Read, an experimental program to offer free, read-online limited use access to anyone who registers for a MyJSTOR account. The program was greatly expanded in late 2012 and currently makes more than 1,300 journals available for online reading with a free account.
Most recently, in September 2013 we launched JPASS, our latest effort to make JSTOR available to people beyond universities, colleges, and high schools. With JPASS, individuals can choose a monthly or annual pass that provides access to more than 1,500 journals from JSTOR's archive collection.
10. JSTOR supports data and text mining.
JSTOR first started thinking about data and text mining back in 1999, when we learned that Fred Shapiro was using JSTOR to find the earliest known uses of words that pre-dated the record of first uses of terms from the Oxford English Dictionary. In 2008, JSTOR introduced the “Data for Research” (DfR) service, a free data mining tool for journal content on JSTOR, available to the public. DfR provides the ability to obtain data sets via bulk downloads, and includes a powerful faceted search interface, online viewing of document-level data, downloadable datasets (including word frequencies, citations, key terms, and ngrams). More than 700 data sets have been downloaded annually since the service launched. We also receive many special requests for access to even larger-scale datasets for research of various kinds and we work with researchers to tailor datasets to their needs.

Economagic.com: Economic Time Series Page
This page is meant to be a comprehensive site of free, eas...ily available economic time series data useful for economic research, in particular economic forecasting. This site (set of web pages) was started in 1996 to help students in anApplied Forecasting class. The idea was to give students easy access to large amounts of data, and to be able to quickly get charts of that data. This is also useful during class, so that when we use the computer and overhead projector facility in class, we can quickly retrieve series and do manipulations in class.
At this time, there are more than 200,000 time series for which data and custom charts can be retrieved. Though the greatest utility of this site is the vast number of economic time series, and the easily modified charts of that same data, an overlooked facility of great utility is the availability of Excel files for all series.
The majority of the data is USA data. The core data sets involve US macroeconomic data (that is, for the whole US), but the bulk of the data is employment data by local area -- state, county, MSA, and many cities and towns.

The Centre provides common services for its researchers and for the users of its research, and it obtains funding f...or the activities it develops. In particular, CEPR:
Develops projects and obtains funding for them: The Centre’s Research Fellows approach CEPR with ideas for research initiatives and projects, for which funding is required. The Centre’s staff work with the Research Fellows to develop the project, both in terms of its scientific content, administrative arrangements and budget. CEPR then approaches potential funders, who range from charitable foundations to government departments and central banks.
Administers and executes the projects: Once funding has been obtained for the project, the Centre administers the grant on behalf of the Research Fellow(s) concerned, and takes responsibility for reporting to the donors on the activities undertaken and expenditures incurred under the grant. In order to carry out the research, it is often necessary for the researchers concerned to meet with other members of the project in order to discuss and compare their research results. CEPR therefore organizes over 50 research workshops and conferences annually, for its Research Fellows in order to advance the research. The Centre also distributes the results of this research in the first instance through its Discussion Paper series. These Discussion Papers are circulated widely to other specialists in the research community so that the results of the research receive prompt and thorough professional scrutiny. The Centre produces about 280 Discussion Papers each year. The key results in each are also reported in the quarterly CEPR Bulletin, which circulates to members of the academic and policy communities.
Disseminates the results of the research: Once the research nears completion, the Centre also disseminates the key results of the research to a wide audience in the private sector and the policy community. This dissemination takes place both through publications and meetings. Highlights of the Centre’s research are disseminated through the Centre’s bi-monthly newsletter,European Economic Perspectives, which is distributed to individuals in the private sector and the policy community. CEPR also produces a wide range of reports, books and conference volumes each year. Research results are also presented at public meetings. The Centre organize over 20 lunchtime meetings and briefings a year, predominantly in London, but also in other major European cities such as Bonn, Brussels, Edinburgh, Frankfurt, Paris, Prague, Stockholm and Vienna.
