Cloud Computing - multiple definitions: 1. an updated version of utility computing (virtual servers available over the internet) 2. anything you consume outside the firewall (including conventional outsourcing)
Types of Cloud Computing:
SaaS - ex. salesforce.com - delivers a single app through a browser to customers using a multitenant architecture. No upfront investment required of customers; low cost for providers.
Utility Computing - offers storage and virtual servers that can be accessed on demand. (I don't really understand the difference between this and SaaS).
Web services in the cloud
Platform as a service - you can build your own apps that run on the providers infrastructure.
Managed Service Providers - an app exposed to IT rather than to end users (ex. virus scanning service for email).
Service Commerce Platforms - hybrid of SaaS and MSP
Internet Integration - ex. OpSource - serves SaaS providers

I don't know about this "ultimate form" of communcation the author is pondering. This article seems a bit of a mess to me. It is interesting to conceptualize books as a form of technology with a limited life span, but their life span has obviously been vast thus far and even despite the multitude of benefits of technology to information seeking, books have their place... even if that means the definition of book has to be re-thought.

Cloud computing permits individual usersto access files from any device and allows businesses to lower the cost of investment in storage space.
Closely associated with web 2.0 - emergence of apps - SaaS (software as a service) - google docs is an example.
HaaS (hardware as a service) - Amazon has elastic compute cloud, Google has app engine
Cloud computing may allow centralization of information.

Week 14 Reading Notes
http://www.noplacetohide.net/
None of this is new to me, really, but it is such a daunting thing that it is easy to ignore. As O'Harrow puts it, "where one effort ends, another begins, often with the same technology and aims." Its hard to keep track of the numerous ways information is being collected about us every second. I have always felt that many of America's post-9/11 'security' efforts have been reactionary and inefficient, and this 1984-like world we live in now is just another example. Its like a bad relationship with no boundaries. If you are completely open with your significant other, give them your bank records, email and facebook password, etc., even the most secure foundations of trust will become shaky, and your partner will find whatever it is they want to find - whether it actually exists or not.
http://epic.org/privacy/profiling/tia/
The first thing I notice is that most of this stuff is from 2005 or earlier - is there nothing more recent?
http://greatlibrarynews.blogspot.com/2008/09/myturn-protecting-privacy-rights-in.html
This sounds like a sticky situation - it comes back to knowing the laws and your library's policies, but also understanding the basic rights afforded to citizens (and children, who seem easy to overlook in terms of rights).
I feel like this blog would be more useful with some context (for this class).

Week 13 Reading Notes
https://courseweb.pitt.edu/bbcswebdav/courses/2124_UPITT_LIS_2600_SEC1090/Blossom_Content_Nation_7_Secrets_Social_Media.pdf
Social Media defined as "anything that helps individuals to publish influentially;" "any highly scalable and accessible communications technology or technique that enables any individual to influence groups of other individuals easily."
Interesting points about social media not eliminating human nature - collaboration will not necessarily be easy just because the tools and circumstances under which we can collaborate are easier to manage. This is definitely true of online learning!
I also found secret #5 to be quite interesting:
"SOCIAL MEDIA SECRET #5: Social media has a production model, but its goal is
not mass production from a handful of huge factories, but mass contextualizalion
in millions of small factories to create and aggregate content again and again in
constantly renewable and useful contexts."

This is a nice look at wikis - I use a wiki at my library and found many parallels between our processes. We have delegated sections to maintain, and it is helpful especially because we all work at different locations. Now, users across town can have access to the same resources I know about for children, and my users can get more thorough resume help from the expert in Germantown. It is very useful as a resource.
One problem I have is that formatting is very limited. For a kid's site, I'd like it to be able to be more interactive, but it is very hard to integrate text and graphics in a cohesive way on a wiki.

Social Tagging sites:
de.li.cious - http://delicious.com/
tags.library.upenn.edu/
www.connotea.org/
www.citeulike.org/
Particularly useful paragraph:
"Del.icio.us allows you to forward links to another user, meaning that a curator who created his or her own account can forward links to the main library site. This requires a Webmaster who can then move these links onto the librarys del.icio.us homepage. Alternatively, you can give subject specialists the password for the librarys account. If librarians without specific subject knowledge have the responsibility to choose and tag resources, they can mine sites like the Librarians Internet Index (lii.org) or the C&RL News Internet Resources columns These sites provide quick ways to fill out your site with quality Web sites to get the program off the ground and show its value to the library community. There are, of course, a few risks and issues to consider when implementing social tagging in your library, especially if the site is open for all library patrons to update. One is the wonderfully named spagging, or spam tagging. Users with bad intentions can tag unsuitable sites for their own profit or simply to create havoc. Another issue is the inevitable variation in tags and the varied degree of user understanding of how to choose keywords. Is it englishliterature, englishliterature, english, literature, or books?"
http://www.ted.com/talks/jimmy_wales_on_the_birth_of_wikipedia.html
neutral POV policy - social concept of cooperation surrounding neutrality. Doesn't use the word "truth" because it is too subjective. Keeps the info quality up.
Edits by "anonymous" users - controversial because credentials can't be checked, but only 18% of posts are anonymous, and it hasn't posed much of a problem to quality thus far.
I will be excited to hear more about "freely licensed text books" alluded to at the end of the video.

Week 12 Reading Notes
Current developments and future trends for the OAI Protocol for Metadata Harvesting
Mission of OAI – “to develop and promote interoperability standards that aim to faciliatet the efficient dissemination of content.”
- Developed the Protocol for Metadata Harvesting – a tool that “facilitates interoperability between disparate and diverse collections of metadata through a relatively simple protocol based on common standards.”
OAI world = data providers and repositories – they make their metadata available through the protocol.
Mission of Open Language Archives Community (OLAC) is to create “a worldwide virtual library of language resources through development of community-based standards for archiving and interoperability and a network of interoperable repositories.”
- Uses OAI Protocol to provide access to metadata harvested from 27 data providers
Sheet Music Consortium – group of 4 academic libraries (UCLA, Johns Hopkins, Indiana, Duke) that are building a freely available collection of digitized sheet music.
National Science Digital Library (NSDL) provides access to collections of science-based learning objects.
- Again, OAI protocol is primary means of aggregating the metadata describing this content.
Comprehensive, searchable registry of OAI repositories being developed by UIUC
ERRoLs = Extensible Repository Resource Locators – ERRoL Resolution service automatically extends features to any OIA repository in the UIUC registry instead having to change repository by repository.
Web Search Engines: Part 1
Hundreds of thousands or servers needed for larger search engines.
I never really understood how spamming worked until I read this. Really interesting that spammers create invisible content.
Web Search Engines: Part 2
Inverted file = a concatenation of the postings lists for each distinct term. Two phases to creation – scanning and inversion.
Search engines assign a popularity score to pages based on frequency of clicks and other factors.
Avg query length 2.3 words
BrightPlanet is the only search technology that can make dozens of direct queries simultaneously – ie can organize and retrieve both “deep” and “surface” web content.
Deep web sites tend to be narrower with deeper content than surface sites.
95% of deep web is publicly accessible.
Search engines w/largest # of websites indexed (Google, Northern Light, etc) index no more than 16% of the surface web!
Deep web is 500x larger than surface web
“These observations suggest a splitting within the Internet information search market: search directories that offer hand-picked information chosen from the surface Web to meet popular search needs; search engines for more robust surface-level searches; and server-side content-aggregation vertical "infohubs" for deep Web information to provide answers where comprehensiveness and quality are imperative.”

Week 11 Lab
For Web of Knowledge, I used the following query:
"digital library" in topic AND virtual reference in topic AND 2008-2012 in year published, or Topic=("digital library") AND Topic=(virtual reference) AND Year Published=(2008-2012).
"digital library" in topic AND virtual reference in topic AND 2008-2012 in year published, or Topic=("digital library") AND Topic=(virtual reference) AND Year Published=(2008-2012).
For Google Scholar, I used the following query:
virtual OR reference "digital library" between 2008 and 2012.

Week 11 Reading Notes
“there is a huge difference between providing access to discrete sets of digital collections and providing digital library services.”
I find it interesting how Google fits into all this – I personally think Google, for general search on the web, lacks a real competitor (I would never use anything else). I find Google scholar to be quite cumbersome, however. I wonder if this has to do with something in this article which I didn’t understand: “metadata searching vs. full-text searching.”
- Does this simply mean the searching of metadata vs. the searching of metadata + the rest of the information source in full?
- Does Google Scholar perform a metadata search or full-text?
1994 National Science Foundation launched Digital Libraries Initiative.
Brought together librarians and computer scientists
“While information accession now rests on a highly technical infrastructure, the core function of librarianship remains. The information must be organized, collated, and presented.”
Interesting that Computer Scientists now seem to count on librarians for publishing and organizing of their scholarly material, and that this may be the road for other disciplines.
“The development of free,
publicly accessible journal article collections in disciplines such as high-energy
physics has demonstrated ways in which the network can change scholarly
communication by altering dissemination and access patterns; separately, the
development of a series of extraordinary digital works had at least suggested
the potential of creative authorship specifically for the digital medium to
transform the presentation and transmission of scholarship.”
DSpace is a model institutional repository system
This is exciting to me as a student and library professional in general, but I wonder how it applies to public libraries…
