If Stanford does not currently have data that you need, you should check
the
ICPSR Data Archive
which houses approximately 5,000 titles. ICPSR data is restricted to the
Stanford faculty, staff, and students and is for use in research and instruction.
Stanford University is a member of the Consortium's ICPSR Direct Program,
so ICPSR data can be downloaded directly from any computer within Stanford's
central campus network or via Stanford's
proxy server.
Search the
ICPSR Data Archive
by title, study number, investigator, or subject term. View study descriptions
or related literature. You will be prompted for your Stanford email address
in order to download any data at ICPSR.
If you prefer to have SSDS load your data on our disk space in the Leland
Systems, then complete and submit our
SSDS ICPSR Dataset Request Form
.
You will need a SUNet ID to
make a request. Complete one form per ICPSR study with the dataset's title
and study number from your ICPSR Data Archive search. In general, data
requests will be available on our Leland Systems disk space within one
working day.
To find out how to access your ICPSR data once it is available, see
Getting and Using Data on SSDS Disk Space.
Almost all ICPSR studies have electronic format codebooks (pdf, text,
or Word documents) that can be downloaded directly. Some codebooks are
only available in printed format. Stanford users can check the online
catalog Socrates
for availability or request that the Library order a printed copy using
our
SSDS ICPSR Dataset Request Form
.
A quick way to see if the library owns a printed copy of an ICPSR codebook
is to do a 'Keyword' search with 'ICPSR' and the ICPSR study number (e.g.,
'ICPSR 7937'). The call number and location of any printed copies of the
codebook will be listed in the 'Long' record for that dataset title. Generally,
printed codebooks take 1-2 weeks to arrive from ICPSR. The requestor has
first crack at these printed codebooks. They will then be added to the
Stanford University Libraries collection and cataloged in Socrates.
In addition to the codebook and data files, some ICPSR studies will also
come with SPSS or SAS file definition (syntax) code, which can be modified
and run to load the raw text (ASCII) data file into that statistical package.
Some ICPSR studies come with the data already formatted for a statistical
package (e.g., SPSS portable or SAS transport files). These files can be
directly imported into the corresponding statistical package. A few ICPSR
studies come with Stata 'do' and dictionary files, which can be used to
input the raw data into Stata. Finally, some older ICPSR studies come with
OSIRIS data and dictionary files (an old IBM mainframe statistical package).
OSIRIS files from ICPSR can be converted to other statistical packages using
the utility Stat/Transfer. Contact us
for help with modifying your downloaded files, with Stat/Transfer or with
any of the statistical packages mentioned.
ICPSR hosts a variety of special topic archives, including: Health and
Medical Care Archive (HMCA), International Archive of Education Data (IAED),
National Archive of Computerized Data on Aging (NACDA), National Archive
of Criminal Justice Data (NACJD), Substance Abuse & Mental Health Data
Archive (SAMHDA), Data Documentation Initiative (DDI), and Census 2000
at ICPSR. A link to the Special Topic Archives is on the
ICPSR Web site.
If you cannot find the data that you need at ICPSR, then check out the
other selections under '
