Journal Storage is a digital library created by the Andrew W. Mellon Foundation in 1995, well known as JSTOR. The JSTOR home page is www.jstor.org. The main language is English, it also includes content in other languages. The owner of JSTOR is now ITHAKA, a non-profit organization founded in 2003 that has the mission of incubating promising new projects that support the use of technology to benefit higher education. It is built to hold digitized academic journals. Now also includes books, primary sources, and current journal issues. The identification and description of JSTORJSTOR was initiated in seven different libraries and originally included ten economics and history journals. It was originally conceived to be a solution to one of the problems faced by libraries due to the growing number of academic journals in existence, especially academic libraries. Because most libraries found it expensive to maintain a complete collection of journals. By digitizing journals, JSTOR could allow libraries to outsource the storage of these journals so that they remain available in the long term. JSTOR provides full text searches of nearly 2,000 journals. More than 8,000 institutions in more than 160 countries have access to JSTOR; most access is via subscription, but some older public domain content is freely available to anyone. JSTOR improves its access based on feedback from its initial websites and has become a fully searchable index accessible from any regular web browser. To make the images and graphs clear and readable, special software has been implemented. In 2012, JSTOR launched a program that provides individual scholars and researchers who register with it with a limited, free...... half of the paper......st Journals on JSTOR are controlled by a "moving wall ", i.e. an agreed delay between the current volume of the journal and the last volume available on JSTOR. This time period is specified by the agreement between JSTOR and the publisher and is usually between three and five years. Publishers can request the period to be changed or request termination of coverage. Previously publishers could also request that the "moving wall" be changed to a "fixed wall" - a specific date after which JSTOR would not add new volumes to its database. Therefore users may not be able to find current articles. And that's the limitation of JSTOR. I really like the interface of JSTOR, especially the fonts, symbols and images. The layout is very welcome. It's clean and useful. There are tutorials and search tools that guide users on how to use it. So I think it's a good academic digital library.
