Washington, DC--The Association of Research Libraries (ARL) has published the ARL Preservation Statistics 2006-2007, a compilation of data on the levels of preservation efforts in ARL libraries throughout North America.

Highlights from the report suggest that the patterns of preservation activities may be changing, with digitization increasing and microfilming declining. 112 ARL libraries reported expenditures of $108,278,519 in 2006-2007 with a total 1,149.13 library-wide preservation staff engaged in preservation duties.

"Also on the site is a link to the draft, "How to Start Building a SUSHI Service." This work in progress by Tommy Barker, Software Engineer, IT and Digital Development at the University of Pennsylvania Library, is a valuable tool for those interested in getting started with building a client.

"I am thrilled we no longer have to download spreadsheets to retrieve Counter data," said Barker. "With SUSHI, we can conveniently automate data processing since it adheres to a common web service standard. Additionally, standardization could create a general solution to COUNTER data harvesting, which in turn encourages sharable solutions within the SUSHI community.""

Same sex and unmarried partner household data are collected for those households where the householder and his or her partner are not married, but are living in a close personal relationship. An unmarried partner can be of the same sex or opposite sex of the householder.

An unmarried partner, in an unmarried partner household, is an adult who is unrelated to the householder, but shares living quarters and has a close personal relationship with the householder. This relationship is based on the self-identification of respondents.

Here are some sources for your use:

• The American FactFinder contains two sources:
•  
  • American Community Survey   Table B11009, shows "Unmarried Partner Households by Sex of Partner."
  • Census 2000, Summary File (SF) 1 Table PCT14, "Unmarried Partner Households by Sex of Partner" is available for the nation, state, metropolitan statistical area, city/place, county, and various other geographies.
  • Additionally, same-sex unmarried partner household data were collected in the 1990 Census. The Technical Note on Same-Sex Unmarried Partner Data From the 1990 and 2000 Censuses provides guidance on comparing these data.
• The Census 2000 special reports include:
  • Married-Couple and Unmarried Partner Households: 2000 and
  • Population and Housing Table, PHC-T-19, Hispanic Origin and Race of Coupled Households provides race and gender for unmarried partner households for the U.S.
• The Census Bureau also collects data for same sex and unmarried partner households in ongoing survey programs, but does not regularly produce tabulations on this topic. For more information and special studies on the subjects of same gender couples and unmarried partner households based on the Census Bureau's survey programs, visit the Population Division Working Papers:
•  
  • No. 34, Unbinding the Ties: Edit Effects of Marital Status on Same Gender Couples.
  • No. 35, Racial-Ethnic and Gender Differences in Returns to Cohabitation and Marriage: Evidence for the Current Population Survey.
  • No. 36, How Does POSSLQ Measure Up? Historical Estimates of Cohabitation.

Google maps mashup includes data on population, housing cost, housing market, schools, safety, health, climate, income/work, and age ethnicity for the continental US.

annoyingly, their "explains" don't say where the data comes from, so it's hard to know how up to date it is. However, it's neat.

Digitization has the potential to transform scholarly use of data found in print statistical publications. While presenting images of statistical tables in a digital library environment may be desirable, the full potential of such material can be realized only if the resulting digital objects are easy to search and manipulate and are accompanied by sufficient metadata to support extraction of numbers from tables and comparison of numbers across tables.
