CSS Tutorial:

-Allows the user to get a very basic feel for the usage and application of CSS in HTML formats
-Tutors on basic tasks such as adding a specific format, color, style, or links
-Shows that with CSS it really streamlines the HTML writing process, allowing simple substitutions and saving time
-Because it provides a template sample, this can serve as a jumping off point when beginning a CSS project
-Provides examples of issues that are encountered and their basic root and solutions
-A very useful tool in beginning to understand CSS and it's relationship to HTML

Cascading Style Sheets Chapter 2:

-CSS allows HTML to mark up in terms of their formatting
-Makes the whole process more user friendly
-CSS pages can be created using style sheets, or built in software by web developers
-Style sheets function as rules, creating a template for CSS creation
-In design, CSS is based around the concept of speed and brevity
-In the past, CSS required browser support, however currently nearly all web browsers include  CSS support
-The top down management system in CSS is referred to as a tree
-Branches are indented to represent physical items in the page
-Most items will be inherited, or after entered once will repeat to save time
-Color and background are the most common aspects used for CSS
-Other common tasks include font style and margins
-Compared to most other web building CSS gives a defined structure allowing venture web builders an easier interface to use

Reading 2: http://www.w3schools.com/HTML/html_intro.asp

-Stands for HyperText Markup Language
-Structured around series of markup tags
-Usually tags are structured in pairs to open and close, or begin or end
-Web Browsers read and translate HTML into graphical interface
-On 5th Generation of HTML although it isn't in heavy use
-<!DOCTYPE> is tag which allows decoding of reading of page
-HTML can be edited with third party software from companies such as Microsoft and Adobe
-An HTML element is everything from the start tag to the end tag including displayed information
-HTML can have empty elements
-Attributes are additional information included in tags during creation process
-Attributes are always contained in the start tag and should always be in quotes
-Headings are defined by <h1> and are numbered in order of priority
-Paragraphs are defined by <p> and may also contain line breaks
-Formatting is used to make text alterations such as bold <b> or italics <i>
-Hyperlinking is defined by <a> and often contains additional attributes
-Cascading Style Sheets are used to emphasize syntax within a production
-Images are defined with <img> and often come from internet resources
-Tables are created with <table> or <tr>
-Lists can be created with structure or not <ul> or <sl>
-Layouts of HTML webpages are a collection of the previously mentioned tags ordered through <div> tags
-Colors are coded though RGB codes
-These codes are separated by name or code value
-URL is the link to an HTML page

Reading 3: http://books.google.com/books?id=l_MFZYMv3YgC&pg=PA15&lpg=PA15&dq=introduction+to+html+pratter&source=bl&ots=nXRgMFYZHz&sig=muV0UY1c_ePZO1pcdu8_V_IdbwQ&hl=en&sa=X&ei=Mvs4ULG9O4Gf6QG8h4GICw&ved=0CC0Q6AEwAA#v=onepage&q=introduction%20to%20html%20pratter&f=false

This chapter of Web Development with SAS by Example expands on the basic topics in the previous reading, giving an in-depth explanation of the processing and in-depth examples and templates of how an HTML production should look during creation.  Provided as well are graphical outputs showing how the actual code and tags connects to the visual interface of the web browser, giving the student/user a good look at how to effectively encode an HTML page.  Also explained within are the differences between XHTML and HTML and their uses and procedures, as well as the effectiveness of various media formats, such as .gif, .png, .wmv within the interface.  Again, coupled with the previous resource, these are the foundation for understanding and implementing HTML.

Reading 4: 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.

T    This text examines the usage of HTML within Content Management Libraries through a series of case studies.  Starting with pre-HTML, low security library systems, the article goes on to analyze the benefits of HTML in such a system.  In building a CMS, it will focus on managing the day to day activities of reference in the library web guide, including titles, subjects, authors, etc.  The main question presented is whether to use a commercial structure or an in-house production.  The benefits of commercial CMS are their efficiency, but the main drawback are high costs for third party software and IT managers.  For in-house productions, the costs are much lower, however there is a less refined feel and understanding when it comes to the final production.  The case study focused on in this article is the implementation of a HTML CMS at Georgia State University, starting in 2002.  They focus on their use of proprietary Microsoft MySQL Software which provides an intricate networking of programming and code that makes up their CMS.  The example of GSU provides a template, the case study states, showing the development and evolution of the program, going from a relatively basic structure to an intricate system of reference management with a complex virtual interface.  The authors contend that this model can be used for other, less funded institutions to create their own CMS without ridiculous expenditures.

Will the incorporation of internet browser plug-ins effectively spell the end of the software era, if all programs can be integrated to work within a browser format?

In the development of internet networking, mainly the switch to TCP/IP networking, were there more efficient systems that fell to the wayside due to costs of maintenance and upkeep?

Reading 1 - http://en.wikipedia.org/wiki/Local_Area_Network

-Local Area Networking interconnects computers within a limited area (home, school, etc)
-Characteristics are high-speed transfer, small geographic area, and leased telecommunication lines
-Ethernet and Wi-Fi are most common distributors
-Developed in Professional World (Xerox and Chase Bank) in the 1970s
-With Personal Computers, LAN grew to meet standards of saving storage space and to communicate
-TCP/IP has become LAN standard
-Originally cables were Coaxial but evolved into Fiber Optics

Reading 3 - Coyle, K. (2005). Management of RFID in libraries. Journal of Academic Librarianship, 31(5), 486-489.

-RFID - Radio Frequency Identifier - consists of computer chip and antenna printed on a medium
-Unlike barcodes, does not have to be visible to be read
-RFID isn't a single technology, there are hundreds of different products on the market
-Used in drug production and to prevent online piracy
-Excels in economic market, still developing in the library trade
-Hard to apply to Library Science because of perceived "throw away" nature
-Security issues also create issues for practical use
-There are positives, allows for quicker and easier scanning of multiple items
-Provides exact calculations of use and timing
-Libraries rarely see return on investment, making it tough to apply because of it's high-tech expensive nature
-Only practical application would be self-checkout removing reference aspects needed in the library
-Tough to apply to delicate materials such as pamphlets and magazines
-Also has problems reading on digital media such as magnetic or metal disks
-If technology can adapt to be changed without reapplication, it is very viable
-Conclusion: developing, yet potential is wide ranging for library field
