(1) Using PDQ Explore Software to Mine
Public Use Microfdata Samples

Grace York, the first featured speaker at the Godort of Michigan Spring Meeting held at the Library of Michigan on May 6th, demonstrated how to use PDQ Explore Software to work with Public Use Microdata Samples (PUMS). Public Use Microdata are the raw data from the original census questionnaires with all identifying information edited out. For those willing to learn, you can create your own customized tabulations.

PDQ Explore software is available free to academics and librarians by contacting info@pdq.com. Tell them Grace York sent you! Don't forget to ask for the id and password while you are at it.

Grace also explained where to get Public Use Microdata Sample data for manipulation and passed out a guide and an alphabetical list of housing and population variables to those who attended.

Grace (graceyor@umich.edu) also mentioned that she is available for assistance when you are starting out, as is JoAnne Dionne, Numeric and Spatial Data Services Librarian (jdionne@umich.edu) at the University of Michigan Library. More complex questions may require contacting Lisa Neidert at the Population Studies Center (lisan@umich.edu).

(2) Michigan Center for Geographic Information

Laurie Prange-Gregory (517/373-7910) from the Michigan Center for Geographic Information next gave us an overview of some of the services offered by her agency and provided an online tour of her department's web page at http://www.michigan.gov/cgi.

The mission of her unit, part of the Michigan Department of Information Technology, is to link all available data to geographic location so that state agency personnel and the citizens of Michigan can make more informed decisions on public policy issues. Before the Center was created, various state agencies and other organizations spent lots of time, effort, and money creating their own geographic information tools and data without communicating very much. Now the Center is heavily involved with working with these various entities to pool resources and get the biggest bank for the buck.

In short, the Center for Geographic Information is now responsible for maintaining the statewide GIS base map, or Geographic Framework. This single mapping system contains spatial information on all of the themes most commonly used in applications including transportation, hydrography, government boundaries, pubic land survey sections and geodetic control. For a description of the various versions, see http://www.michigan.gov/cgi/0,1607,7-158--50182--,00.html.

Overwhelmed? Don't despair. Try Map Michigan.

Map Michigan offers a variety of geographic search options. Information that can be displayed ranges from specified addresses, planning a route, street intersections, coordinates, zip codes, points of interest and specialized maps. Points of Interest maps are user-specified features, such as business services, education locations, governmental facilities, travel and recreation locations, and more. Specialized maps consist of items such as schools, boat launches and waterfalls. Check it out at http://www.mcgi.state.mi.us/mapmichigan/home.asp.

Another interesting feature found on the CGI web page includes 1998 Series USGS Digital Orthophoto Quadrangles (DOQ) for each county in the state. So if you want to see what your part of the state looks like from the air, take a look at the Orthophoto Quadrangles.

Other interesting options include:

The Center for Geographic Information is also working on numerous other projects in tandem with other state agencies. For example, some day it will be possible to pull up a map showing where Threatened and Endangered Species are located so that developers won't have any excuse for bulldozing the last known habitat of some exotic creature or plant! Some day it will also be possible to search by community to come up with a list, descriptions, and locations of Historic Sites Online. A Department of Transportation Asset Management System is scheduled for release next year.

For those interested in viewing images of historical maps linked from the Center for Geographic Information web page, take a look at:

Another historical feature linked from the CGI web page is Paper Trails: The Michigan Highway Map, an article by LeRoy Burnett from the Nov/Dec. 1999 Michigan History Magazine.

(3) Map Librarianship

Kathleen Weessies, Maps/GIS Librarian for the Michigan State University Libraries Map Library, next provided an overview of the nuts and bolts of Map Librarianship.

The MSU Map Library collects a wide array of maps on its own as well as housing maps for the Library of Michigan Regional Depository Library. Figuring out the best way to arrange, classify, and post information about them in the MSU Library Catalog and on the web is a real challenge.

For more details, review the powerpoint copy of her Map Librarianship Presentation.

(5) Spring Depository Library Council Meeting,
April 18-21, St Louis, MO

Following the election, the various librarians and staff attending the Spring Godort of Michigan meeting shared comments on the recent Spring Depository Library Council Meeting and other topics before adjourning. Since the Red Tape Editor was filling the effects of three trips through the fabulous buffet line arranged by Shawn Nicholson, our program coordinator, his notes are covered by mustard sauce and various other food stains, making them virtually indecipherable, so he has decided to substitute the following review of the Spring Depository Library Council Meeting provided by Hui Hua Chua, U.S. Government Documents Librarian at Michigan State University, for the sake of accuracy.

"The Depository Library Council is a group appointed to provide advice on policy matters regarding the U.S. federal depository program to the Public Printer. This biennial meeting provides an opportunity for the Council, Public Printer and depository librarians to discuss issues and policy relating to the depository system. MSU Libraries has been a federal depository since 1907.

The depository system has been in flux for several years, largely due to the increasing trend towards web publication of government information. This biennial meeting was particularly interesting as the Public Printer and Government Printing Office laid out plans for the future of the depository system and sought reactions and comment.

GPO proposals and related documents:

Reactions to these proposals ranged from skepticism regarding the costs and estimated number of pages to be digitized to concern that more emphasis should be placed on preserving born-digital documents, which are more likely to be lost than historical paper/fiche collections. Proposals described above are open for comment, and are strongly encouraged.

With the prospect of an all-electronic depository collection and system within the next 5-10 years, a major theme was the role and relevance of a depository library in the all-electronic future.

Some interesting suggestions included:

In a separate meeting, there was a suggestion that the current depository library system would end in the next 2-10 years, and that different types of government information products and services might be provided for a fee.

This was a busy and intense meeting, with many other issues discussed. If you have further questions, feel free to contact: Hui Hua Chua, U.S. Documents Librarian, 100 Library, Michigan State University, East Lansing, MI 48824-1048; Telephone: 517-432-6123 ext. 109; Fax: 517-432-1192; Email: chua@mail.lib.msu.edu."

Bernadette Bartlett from the Library of Michigan also offered to provide more information since she was able to attend the conference as well due to Ann Sander's emergency appendectomy the day before the conference started!

At the conclusion, all Godort of Michigan members and other guests attending the meeting congratulated the speakers and Shawn Nicholson for putting together an awesome program.
