About PCC Statistics

This document is a guide to the content of the PCC statistical displays and the schedules used for collecting data. Links on the PCC Statistics page package the record production figures of Program for Cooperative Cataloging (PCC) members in various configurations and schedules:

What reports are in the four columns on the PCC Statistics page?

Annual Column:

The Summary FYXX—displays on one page the totals for each type of record, compared to the number of records contributed in the previous year.
The All Libraries FYXX—displays in a multi-page report every PCC institution’s MARC code and name, grouped according to program, and its record contributions.

Monthly Column:

MONTH XXXX—displays every PCC institution’s MARC code and name, grouped according to program, with data in 10 different record categories (see below). NACO and SACOrecord contributionsare tallied monthly, filling the appropriate record categories columns for those programs. December, March, June, and September monthly reports will include data in the CONSER-related columns, due to the quarterly reporting schedule. March and September monthly reports will include data in the BIBCO column, due to the semiannual reporting schedule.

Funnel Project Summaries Column:

By Project FYXXXX—displays the name of every PCC funnel and one set of record totals for the year or midyear; expressescomposite funnel totals as a percentage of all PCC contributions.
By Library for All Projects—displays a report for each project, showingeach project member’s MARC code, institution name, and record contributions; expresseseachproject’s totals as a percentage of all PCC contributions.

International Partners Column:

FYXXXX—displays the MARC code, name, and record contributions of all non-US PCC member institutions; expresses totals as a percentage of all PCC contributions.

What does it mean when libraries are “grouped according to program” in certain reports?

When the reports were being designed, PCC leadership wanted to sort member institutions by the types of records they produced and their levels of involvement in one or more of the PCC programs. Within each grouping, the members are arranged alphabetically by institution name. The reports use this arrangement: Summary FYXXXX, All Libraries FYXXXX, and MonthXXXX.

BIBCO and CONSER libraries are the first group, presented prominently because generally they produce records for two or more programs.
NACO Institutional members appear in the second group.
NACO Funnel projects are in the third group, called “Multi-library NACO Projects”.
SACO Institutional members appear in the fourth group.
SACO Funnel projects are in the fifth group, called “Multi-library SACO Projects”.
DLC Coop contributions show the records contributed by the Cooperative Programs Section and other designated LC staff in support of the PCC.

What record categories do the ten data columns in the reports represent?

NACOcategories (basic level):

New Names—name authority records added to the LC/NACO authority file
Chg Names—changes/modifications to existing name authority records

NACO categories (advanced level):

New Series—new series authority records
Chg Series—changes/modifications to existing series authority records

BIBCO category

BIBCO--monographic bibliographic records for books, cartographic material, sound recordings, etc. that have been added to a BIBCO-participating database either as a newly created record, or as an existing record updated and coded as a BIBCO record.

CONSER categories for serials (journals, newspapers, etc.):

CONSER Auth—new serial bibliographic record “Authentications”, added to the CONSER database in OCLC
CONSER Maint—Maintenance, or changes to authenticated serial records already in the CONSER database

SACO categories:

New Subject—New topical headings added to the Library of Congress Subject Headings (LCSH) list
Chg Subject—Modifications to existing subject headings in LCSH
New/Ch Cls. nos.—New alpha-numeric classifications and modifications to existing classifications in the Library of Congress Classification schedules. Typically, contributions are modest, so the new and changed records are added together to save space on the spreadsheet.

What does a zero “0” mean?

In the current statistical displays, a zero “0” in any column may indicate any of these conditions:

The participant has not joined the program related to this column.
The participant is a current member in that program, but has sent no records in this category during the reporting period.
Record contributions for the program related to this column are collected and displayed on a schedule that doesnot fall during the reporting period.

LC’s Cooperative Programs Section is working to eliminate this ambiguity.

What comparisons appear in the PCC stats?

Many reports simply list PCC record production for the current and previous fiscal years, giving the current totals as a percentage of the previous year’s totals.

Reports for multiple-library projects, or funnels, present the totals of the specifiedproject, the totals for the entire PCC membership, and the project’s records as a percentage of the total PCC records for the time period.

The Library of Congress is a PCC partner--where are their stats?

CONSER serial record contributions by LC staff appear in the current displays.
BIBCO, NACO, and SACO contributions by LC staff members are not included in the PCC statistics at this time.
