Preliminary Authority Records

I've set up a poll on old preliminary records. Just for fun or to vent.

Off Topic - Gaming

Well, those gaming librarians have recruited me. I've always thought libraries should have games. Why not? They have romance novels, DVDs, CDs, all sorts of popular materials. But I never had any interest in games. I'd tried Pong and Space Invaders and a couple of others over the years but they didn't appeal to me. Then we gave a home to two kids and last Christmas got a Wii for the family. These games weren't your parent's games. Super Mario Galaxy and Lego Star Wars: The Complete Saga were both imaginative and engaging. My TV time, never too much, disappeared for months.

Recently for my birthday I received a Nintendo DS Lite. Nice graphics, fast enough, small enough to enjoy. I started playing Brain Age: Train Your Brain in Minutes a Day!. But soon I also picked up Hotel Dusk: Room 215 and Lego Indiana Jones: The Original Adventures. If you haven't tried video games in a dozen years, you will be surprised at just how more enjoyable they have become. Since I'm new to this I'm open to suggestion from any more knowledgeable sources.

Preliminary Authority Records

I'm bothered by authority records at remaining as preliminary for 25 years or so. Seems like we should be wary of using preliminary things. If a piece of software is marketed as preliminary or beta, I'd only use it in controlled situations. Yet some of these preliminary headings have been used to create name/title authority records. Just how many are there? Well, in our small library here are the headings marked as preliminary in our catalog.

Will some of these no longer be preliminary when death dates are added? Not necessarily. Many of these have been updated over the years as a look at the 005 will show, yet they are still preliminary. /rant


The proposals and discussion papers discussed at the Midwinter 2009 MARBI meetings have been updated to include brief summaries of discussions and decisions made.

Document Summarization using Wikipedia

Document Summarization using Wikipedia by Krishnan Ramanathan, Yogesh Sankarasubramaniam, Nidhi Mathur, and Ajay Gupta is a recent HP Technical Report. It seems the small screens used by mobile devices are creating a demand for document summarization.
Although most of the developing world is likely to first access the Internet through mobile phones, mobile devices are constrained by screen space, bandwidth and limited attention span. Single document summarization techniques have the potential to simplify information consumption on mobile phones by presenting only the most relevant information contained in the document. In this paper we present a language independent single-document summarization method. We map document sentences to semantic concepts in Wikipedia and select sentences for the summary based on the frequency of the mapped-to concepts. Our evaluation on English documents using the ROUGE package indicates our summarization method is competitive with the state of the art in single document summarization.

Google, Yahoo and MSN Agree on the Canonical Link Tag

Google, Yahoo and MSN Agree on the Canonical Link Tag. Nice and simple.
The latest news coming from the the three major search engines is a major improvement to how Websites are indexed by search engines. The idea of the Canonical Link Tag is that a website owner can specify a preferred version of a particular URL. What does that mean? If your site has identical or similar content (accessible through several different URLs), the Canonical link tag helps search engines calculate the most preferred URL. How Does it Operate? The tag is part of the HTML header on a web page, the same section you’d find the Title attribute and Meta Description tag. In fact, this tag isn’t new, but like nofollow, simply uses a new rel parameter. For example:

link rel="canonical" href=""

This would tell Yahoo!, MSN or Google that this page, where you place the tag will be treated as Therefore all links, as well as content metrics a search engine would apply should tie back to that URL as though it were one and the same.

Metadata Remediation Tools

Future Directions in Metadata Remediation for Metadata Aggregators by Greta de Groat describes tools used by digital libraries on metadata aggregations.
This report will detail the current state of the art of remediation efforts, describe the additional services that aggregators could offer if the metadata were there to support them, and identify the types of tools that are needed to remediate the metadata in order to achieve the desired level of service. The report is aimed toward designers of metadata aggregations, including programmers, project planners, and metadata specialists. Knowledge domains such as computer science, informatics, information retrieval, information science, and library science are within the scope of the report. It is assumed that remediation efforts will be focused on working with the metadata itself, as many aggregators do not have access to the raw digital item.
