Data, data everywhere

Data, data everywhere
WHEN the Sloan Digital Sky Survey started work in 2000, its telescope in New Mexico collected more data in its first few weeks than had been amassed in the entire history of astronomy. Now, a decade later, its archive contains a whopping 140 terabytes of information. A successor, the Large Synoptic Survey Telescope, due to come on stream in Chile in 2016, will acquire that quantity of data every five days. Such astronomical amounts of information can be found closer to Earth too. Wal-Mart, a retail giant, handles more than 1m customer transactions every hour, feeding databases estimated at more than 2.5 petabytes—the equivalent of 167 times the books in America's Library of Congress (see article for an explanation of how data are quantified). Facebook, a social-networking website, is home to 40 billion photos. All these examples tell the same story: that the world contains an unimaginably vast amount of digital information which is getting ever vaster ever more rapidly. Dross into gold

10 best book and library infographics of 2015 In the list below, you’ll find the most spectacular and engaging infographics about books, libraries, and reading, that were created in 2015. Infographics are still one of the greatest and most appealing ways of sharing facts, numbers, mechanisms, and ideas. When it comes to books, libraries, and everything related to writing and reading, it was a good year. And very well documented in numerous charts, infographics, and other visuals. One big trend to observe in 2015 was about highlighting characters, objects, props, or quotes from the works of literature. We’ve seen memorable literary animals, plants, or monsters.

10 Tips for (journalists) Designing Infographics This article was originally published on “Digital Newsgathering”, a class blog for Journalism 226 at San Francisco State University, Instructor: Staci Baird. I wrote this post as a guest author, and with permission I am republishing it here. Assuming you’re not working for a media corporation with huge graphics and statistics departments at your disposal, you may want to create some infographics for your own articles. With today’s flood of information, infographics allow readers to quickly digest and understand complex data. PREMIS: Preservation Metadata Maintenance Activity The PREMIS Data Dictionary for Preservation Metadata is the international standard for metadata to support the preservation of digital objects and ensure their long-term usability. Developed by an international team of experts, PREMIS is implemented in digital preservation projects around the world, and support for PREMIS is incorporated into a number of commercial and open-source digital preservation tools and systems. The PREMIS Editorial Committee coordinates revisions and implementation of the standard, which consists of the Data Dictionary, an XML schema, and supporting documentation.

The Amount of Information in the World According to the latest accounting of how much information capacity there is in the world, the tide of information we have unleashed is rising far faster than anyone expected. The flood of information is now a long-term tsunami. Computing capacity is increasing at 58% annually, telecommunications at 28%, and storage at 23% per year. Lessons of the Victorian data revolution Ken Cukier recently wrote about how useful analogies from the past are in explaining the potential of the current data revolution. Science as we know it was consciously created in the 19th century, and in many ways the current wave of data techniques feels like an echo of that first flood of innovations. It’s fascinating to read histories of the era like “The Philosophical Breakfast Club” and spot the parallels. Take tides for example. You’ve probably never worried about the timing or height of the sea, but for Victorian sailors figuring out the tides was a life or death problem.

So you want to be a Data Visualization Librarian? So you know that you want to be a librarian, but have you thought about specializing in a certain field? Maybe you have an interest in emerging technologies or you want to work with researchers and students across the disciplines? Data visualization is a hot topic in librarianship, and specializations in data analytics and visualization is an exciting area of growth in the profession. I sat down with four visualization specialists who work within the University of Michigan Library system to get an idea of what their jobs entail.

Automation Marketplace 2012: The Complete Survey Data Data collected by Marshall Breeding, Director for Innovative Technology and Research, Vanderbilt University, Nashville The following charts provide the complete statistical report for the 2012 automation marketplace. Note: at the top of each table is a search box that allows you to filter rows in the table that follows. 2011 Sales by Category How much information is there in the world? Abstract How much information is there in the world? This paper makes various estimates and compares the answers with the estimates of disk and tape sales, and size of all human memory. There may be a few thousand petabytes [*] of information all told; and the production of tape and disk will reach that level by the year 2000. So in only a few years, (a) we will be able save everything \- no information will have to be thrown out, and (b) the typical piece of information will never be looked at by a human being. Here is a chart of the current amount of online storage, comparing both commercial servers [Tenopir 1997]. and the Web [Markoff 1997].
