Week 8: Reading Notes
1) W3 School Cascading Style Sheet Tutorial: http://www.w3schools.com/css/
CSS = Cascading Style Sheets
CSS was created to solve the problem of formatting tags, like font tags, to create style on an HTML page.
Styles are saved in external .css files, allowing the web developer to change the appearance or all the pages in a web site by editing only one file.
CSS declarations end with a semicolon and are grouped with curly brackets.
{color:green;
text-align:center;}
Comments are used to explain codes. They begin with /* and end with */.
External Style Sheets are ideal for many pages.
Internal Style Sheets are ideal for single documents.
2) CSS tutorial: starting with HTML + CSS http://www.w3.org/Style/Examples/011/firstcss
While the first tutorial is extremely in-depth, from basic to advanced CSS coding, I enjoyed this CSS tutorial more. Its step-by-step process involves the user more in actual coding rather than standard explanations with multiple chapter pages.
3) chapter 2 of the book Cascading Style Sheets, designing for the Web, by Håkon Wium Lie and Bert Bos (2nd edition, 1999, Addison Wesley, ISBN 0-201-59625-3)http://www.w3.org/Style/LieBos2e/enter/
Rule - a statement about one stylistic aspect of one or more elements
Style sheet - a set of one or more rules that apply to an HTML document
A rule contains two parts: selector and declaration. Selector is before the curly brackets, the declaration is within the brackets.
The selector specifies which part of the HTML document will be affected by the declaration, while the declaration is the rule that includes the effect, such as color.
h1 {color: red}
Fonts:
h1 {color: red;
font: 36pt serif}
or
h1 {font-style: italic;
font-weight: bold}
Fonts:
h1 {color: red;
font: 36pt serif}
or
h1 {font-style: italic;
font-weight: bold}

Week 7: Reading Notes
1) W3schools HTML Tutorial: http://www.w3schools.com/HTML/
I already know basic HTML, but this tutorial was a nice review of paragraphs, headings, start tags and end tags. As the tutorial became more in-depth in basic formats, I appreciated the refresher course on more difficult codes like frames, which I would always need to look up in the past.
<html>
<frameset rows="25%,50%,25%">
<frame src="frame_a.htm" />
<frame src="frame_b.htm" />
<frame src="frame_c.htm" />
</frameset>
</html>
The advanced, media, XHTML (or XML), and reference sections are great resources for future reference!
2) HTML Cheatsheet http://www.wired.com/images/multimedia/webmonkeycheatsheet_full.pdf
This cheatsheet is also a good reference, but I would prefer looking up codes in the previous tutorial, as you could easily see how they work (and quickly test them) all within one or two pages.
3) Goans, D., Leach, G., & Vogel, T. M. (2006). Beyond HTML: Developing and re-imagining library web guides in a content management system. Library Hi Tech, 24(1), 29-53.
Options:
-FrontPage
-Open source
-In-house
I understand databases are used to keep track of updating library web guides, but how they connect to formatting is still a difficult concept for me. Whether one uses the content management system itself, or code in FrontPage or another format, is up to the librarian/library. I would probably better understand how the transition occurs in a real-time process, or shadowing someone like a web development librarian, a title referenced in the article.

Week 6: Reading Notes
1) Tyson, Jeff. http://computer.howstuffworks.com/internet-infrastructure.htm/printable
-No one owns the Internet.
-The Internet grew from four host computers in 1969 to tens of millions computers today.
-The Internet Society formed in 1992 to develop policies and protocols to define our actions online.
-Computer Network Hierarchy
-Domain Name System (DNS) was created by University of Wisconsin in 1983 to map text names to IP addresses, so a user only needs to remember the website name--not its IP address.
-URL: Uniform Resource Locator
-HTTP: Hypertext Transfer Protocol
2) Andrew K. Pace “Dismantling Integrated Library Systems” Library Journal, vol 129 Issue 2, p34-36. 2/1/2004 http://www.libraryjournal.com/article/CA374953.html
-Competitive ILSs
-Starting over, comparing moderate user levels to servicing thousands over the web
-ILS versus "Internet-savvy end users"
-Open Source Software (OSS) as solution?
-"Library systems are changing because library assets are changing..." - Verne Coppi, Endeavor's VP for development
3) Sergey Brin and Larry Page: Inside the Google machine. http://www.ted.com/index.php/talks/sergey_brin_and_larry_page_on_google.html
-"Pretty much everywhere there's power, there's the Internet." - on why there are so many Google queries around the globe, although they need to work on Africa.
-Algorithms are not perfect or smart.
-Everyone has access all around the world? (Noted earlier in lecture that Africa needs help...but so do countries with censorship issues since lecture was made in 2004. Does Google need to update this lecture with digital divide issues?)
-Responsibility to provide people with the right information.
-Never accepts payment for search results, just makes money from advertising.
-Thinks like a "newspaper."
-Tremendous impact on the world.

4) A Few Thoughts on the Google Books Library Project http://www.educause.edu/EDUCAUSE+Quarterly/EDUCAUSEQuarterlyMagazineVolum/AFewThoughtsontheGoogleBooksLi/162510
-The author marvels at the prospect of having so much digital information at our disposal.
-Author's main argument: "Google's initiative will not make books obsolete; it will make the information in them more widely accessible."
-Fascinating, if not true, concept: "Once users have become accustomed to typing in queries, they want to know why they can't find everything in a like manner."

Week 4 Lab
Task 1:
-Find journal impact factor for Annu Rev Inform Sci in the year 2007.
-MySQL command: SELECT * FROM isi_jcr_report_isls WHERE j_abbr = 'ANNU REV INFORM SCI' AND jcr_year = 2007
-Answer: Impact Factor is 1.936
Task 2:
-Find all journals with impact factor > 1 in year 2008.
-MySQL command: SELECT j_abbr, j_if FROM isi_jcr_report_isls WHERE jcr_year = 2008 and j_if > 1
-Answer: See figure below.

Week 5: Reading Notes
1) Local Area Network: http://en.wikipedia.org/wiki/Local_Area_Network
-Local Area Network = LAN
-Connects computers in a limited area, such as a home, school, or office
-Early LANs used coaxial cables, later models used wi-fi, as less cabling was needed and it was more essential for mobile laptops and phones
-LANs might also be classified as a Metropolitan Area Network (MAN) or Wide Area Network (WAN) depending on distance involved and how connections are established
2) Computer network: http://en.wikipedia.org/wiki/Computer_network
-Computer network: refers to hardware components and communication channels which share information
-Communication protocols: define rules and data formats for exchanging information
Computer network properties:
-faciliate communications
-permit sharing of files, data, and other types of information
-share network and computing resources
-may be insecure
-may interfere with other technologies
-may be difficult to set up
-wired technologies v. wireless technologies v. exotic technologies
Communications protocols:
-Ethernet
-Internet Protocol Suite (or, TCP/IP)
-SONET/SDH
-Asynchronous Transfer Mode
-Network programming
Scale examples:
-Personal Area Network
-Local Area Network
-Storage Area Network
-Campus network
Network topology: layout of the network
Network performance: service quality
3) Coyle, K. (2005). Management of RFID in libraries. Journal of Academic Librarianship, 31(5), 486-489.
"Briefly, the RF in RFID stands for “radio frequency”; the “ID” means “identifier.” The tag itself consists of a computer chip and an antenna, often printed on paper or some other flexible medium. The shortest metaphor is that RFID is like a barcode but is read with an electromagnetic field rather than by a laser beam. The similarity ends there. RFID is an advanced technology compared to barcodes" (486)
-hundreds of different RFID tags on the market today, not a singular technology
*card swipes
*farm animal trackers
Should libraries used RFID?
-Privacy is a large concern
-Technology isn't highly secure
-Best to debate pros and cons and develop policies should RFID becomes a technological standard in the future
