Internet
Through Google search engine I've found a another great website that supports my theme of lifelong learning called Ageless Learner: Curious For Life! (http://agelesslearner.com/). This is an educational website &

Citation Pearl-Growing Search in ASC
Database: Academic Search Complete (ASC)
Strategy: From a previous search using "Lifelong Learning" and "Librar*" as my initial search terms I found an article that's particularly pertinent to my topic, so I use it as my "pearl" and look up its record to see what descriptors may be useful to to retrieve more articles like it.
Title:
Authors:
Barber, Peggy
Source: Reference & User Services Quarterly; Fall2002, Vol. 42 Issue 1, p66, 10p
Subject Terms:
Abstract:
So I added "literacy" to my next search and retrieved 28 hits, with my "pearl" as hit #22:
Evaluation: This strategy greatly improves recall, and that's why it's also called the "snowballing approach." The search terms can be modified along the way depending on the retrieved results. For example from record #23 above there are subject terms that may be incorporated in the next search to retrieve more pertinent results in this particular database:
- Subject Terms:
- *PUBLIC libraries
*INFORMATION literacy
From doing these search excercises I find that each search strategy is best suited for a particular information need, and oftentimes a combination of strategies yields the best results. For instance if the search topic is fairly narrow, then one may start out with the most specific facet first, then if necessary modify the search by the citation pearl-growing approach to improve recall. If the search topic is broad, then either the successive fractions or the building block approach is a more appropriate starting point.

Successive Fractions Search in Project MUSE
Strategy: Start with the broadest concept, "programs"--> 17365 hits, then search "public libra*" within results ---> 4123 hits, then search "lifelong learning" within results ---> 237 hits
Below is the record of a good hit:
You searched for: programs in All Fields w/Text AND public AND librar* in All Fields w/Text AND lifelong AND learning in All Fields w/Text
Search Within Results: | | | |

Evaluation: This strategy is similar to the building block search, except that one starts the search with the broadest concept, then narrows it down successively using Boolean limiters. For this particular topic and this database, it does not seem to matter what order the other concepts are searched within the results from the starting broadest concept. For instance, after getting 17365 hits for "program," I can search for "public libra*" within results and get 4123 hits as above, or I can search for "lifelong learning" within results and get a lot less, 481 hits; either way, when I search within results for the remaining concept, the outcome is exactly the same: 237 hits, same documents, same order of relevancy! Logically, even if there are a million concepts to search through successively, the order of the last two concepts can be switched and the end results would still be the same...neat!
Specific Facet Search in LibLit
My search topic is lifelong learning/resources/ in public libraries. This search starts with the topic's most specific facet which is “lifelong learning.” To increase my chances of finding relevant hits I also include a related term, “continuous education.” I search Library Literature (LibLit) since my next specific facet, “public libraries,” would be partly covered by this database for library literature. Below is the record of a good hit:
Search Results: |
1776 Records found for (lifelong learning) |

Evaluation: This is an efficient way to start a search, especially in a topic with more than two concepts (facets), provided the user knows which concept is most specific in the search topic. Otherwise one can search each facet individually to find the most specific facet, i.e. the one that yields the lowest number of hits. In this case the more specific facet is quite evident without having to actually conduct individual searches for each facet. The initial 1776 hits obviously needs to be narrowed down to a manageable number, and Boolean limiters (e.g. AND, WITH) may be used to incorporate the remaining facets in the search topic (in this case "public libraries" and "resources/programs"). In other words, a building block search is the next logical step here. Non-subject limiters such as language, document type, and year of publication can also be applied to further narrow down the search.

Building Block Search in ERIC
Database: Education Resources Information Center (ERIC)
Search strategy: Building block S1 + S2 + S3 --> results
S1 - lifelong learning or continuing education
S2 - public librar*[-y,-ies] or community librar*[-y,-ies]
S3 - resource*[-s] or program*[-s]
Search Criteria in ERIC:
((Keywords:lifelong and Keywords:learning or Keywords:continuing and Keywords:education) and (Keywords:public and Keywords:librar* or Keywords:community and Keywords:librar*) and (Keywords:resource* or Keywords:program*))
My search retrieves 826 hits. Below is the record of first hit:
| |||||||||||||
| |||||||||||||
Descriptors: Abstract: Full-Text Availability Options: |
Evaluation: Due to the broad nature of my topic, the number of retrieved documents is rather high. Because the records are displayed in order of decreasing revelancy, I am able to assess that the retrieval precision is relatively low, dropping off sharply after the first 100 hits or so. To increase the precision I can start the search with the most specific facet in my topic (lifelong learning), then narrow down the results further using Boolean operators (AND public libraries AND resource or program NOT statistics). Non-subjects attributes can also be used to limit the search, for example document type (full-text), language (English), and publication year (after 1999).

The second RSS feed is from the Public Library Association (PLA) weblog at http://plablog.org/. This feed provides regular automatic updtates of public library-related events and topics, supporting my interest in ways public libraries can serve as a platform for lifelong learning and recreation.

My Introductory Post
Today I've created my first weblog ever and it' s for my graduate training in library and information science (LIS). In this blog I will post all my competency requirements for the information storage and retrieval (ISAR) course. My main area of interest is lifelong learning and recreation (hence the title of my blog) and how the public library can be a wellspring of information and resources for this endeavor. I look forward to your feedback/comments. DD
P.S. Below is the link and a sample entry from a related blog, For Greater Knowledge, found through Blog Search Engine. This blog engages library staff and patrons in exercises on the internet including finding websites of learning/recreational value to them. (I chose this particular entry also due to identification with the author's initial reluctance in blogging :o)

Thing #24 - Learning 2.0 Thoughts
Wow! That was a lot to learn in what seems like a very short period of time. I get excited thinking about all the possibilities of using what I've gleaned from these exercises. I knew from the beginning that I would enjoy the discoveries but was a bit apprehensive about the public blog. Despite originally initiating this as an anonymous blog, most of you fellow LPLS bloggers have determined my identity and that's fine. It just seemed less intimidating to begin behind a mask. I have found that I like blogging. The other exercises that I like and know that I will continue to access are:- Flickr mashups and 3rd party sites, especially FD Toys
- Tennessee Virtual Archive (TeVA) and the Nashville Public Library Digital Collection
- LibraryThing
- LPLS staff wiki
- Zoho Writer and Google Docs
- YouTube
