Pls and the public library national data collection process
PLS and the Public Library National Data Collection Process

  • PLS relies on the joint efforts of IMLS, Census, and the states.

  • PLS collection is based on standard items and definitions.

  • Guidance is provided by the Library Statistics Working Group (LSWG).

  • PLS process assures data is submitted electronically in a standard format.

  • The WebPLUS User’s Guide contains data definitions and filing instructions

Input of data to webplus
Input of Data to WebPLUS

  • Data can be entered directly into the software viewing screens

    • This is most often done to correct or update data for a limited number of items

  • Data can be imported (more than once!)

    • Administrative Entities and Outlets data imported separately

  • Importing reduces keying errors

Pls data files
PLS Data Files

State Characteristics File

  • Fiscal Year Reported

  • Population Totals

Population of legal service area

  • Two types of data edit checks

    • Current-year checks

    • Historical checks (based on comparisons of current-year with prior-year data)

  • State data coordinators must provide explanations for the edit flags and file an annotated edit report with the data submission

Survey submission
Survey Submission

  • State submission and IMLS file acceptance is final

    • Census may request additional information during the Edit Follow-up process

  • Public library information from all the states is merged for that year’s data file

  • Missing data is imputed

Why pls
Why PLS?

  • To collect accurate US public library data, we need data that is

    • Valid

    • Reliable

    • Timely

  • “Valid” means we’re reporting what we all agree to report (PLS definitions)

  • “Reliable” means measurement methods are consistent (Edit checks help confirm consistency)

  • “Timely” means within timelines and by due date

  • PLS is the only source of comprehensive national public library data, a voluntary, collaborative effort

Imputed data
Imputed Data

  • Missing data (-1) are imputed for national totals and state ranking purposes

  • Imputed data are included in the national database

    • Imputed data are flagged on the library’s PLS record

    • Imputed data are not displayed on the public library peer comparison tool

  • Rules for imputation differ according to the data (See technical notes)
