Borrower/Lender

For ILL Analyses a library is identified as either the Borrower or the Lender

Holding Status

For ILL Analyses, this dimension shows how many borrowing requests were submitted for items not owned by your library.

Holding Count

For selected analyses, results may be displayed according to the number of libraries that hold a given title.

Shared By

For WorldCat Comparisons, this dimension shows how widely your library's items are held within WorldCat, that is, whether an item is held uniquely by your library or held by you and one, two, three (and so on) other libraries.

Request Date

For ILL Analyses, this dimension shows the total number of items requested (Borrower) or shipped (Lender). You can view data by annual or quarterly totals.

Request Frequency

For ILL Analyses, this dimension shows how often a request was submitted (Borrower) or shipped (Lender). You can view aggregate or annual totals.

Request Cost

For ILL Analyses, this dimension shows how much your library paid (in ranges of U.S. dollars) for items you borrowed.

Copy vs Loan

For ILL Analyses, this dimension shows how many borrowing requests were submitted for items that the library expects back (such as books or videos) versus items that it does not expect to be returned (such as photocopies).

Types of Analyses

The WorldCat Collection Analysis service provides four types of collection analysis.

Individual Library Analysis.  This analysis presents your library's holdings according to the selected analysis dimensions.

ILL Analyses.  This analysis presents your library's borrowing and lending activity within WorldCat Resource Sharing.

Circulation Analysis. This analysis shows how your library’s collection is used within your local community. Data from your library must be sent to OCLC to activate this analysis.

Authoritative List Comparison. This analysis presents your library’s holdings compared to an authoritative collection development list.

Uniqueness

The Uniqueness view of the WorldCat analysis shows how broadly a given title is shared among the members of a group, that is, how many of a library's titles are:

  • held by it alone
  • held by one other library (Shared by 2)
  • held by two other libraries (Shared by 3)

and so on.

For an Authoritative List Comparison, uniqueness shows how many of the Authoritative List titles are not held by your library.

Collection Analysis Screens

Data to Analyze

The Data to Analyze screen lists all of the analyses available to your library.

Analysis Results

The Analysis Results screen presents the results of an analysis in a spreadsheet-style table. Information viewed on this screen includes:

My Library. This analysis presents your library’s holdings – and only your library’s holdings – according to your selected analysis dimensions..

WorldCat Comparison. This analysis compares your library’s holdings to all of WorldCat, according to your selected analysis dimensions. It shows how many of your holdings are unique to your collection and how many are held by other libraries as well.

My Library as Borrower. This analysis presents all WorldCat Resource Sharing requests submitted by your library, via the staff Workform or the Direct Request Workform.

My Library as Lender. This analysis presents all requested items that are physically or electronically shipped from your library.

Circulation Analysis. This analysis shows how your library’s collection is used within your local community. Data from your library must be sent to OCLC to activate this analysis.

Authoritative List Comparison. This analysis presents your library’s holdings compared to an authoritative collection development list such as Booklist or Publisher’s Weekly.

Graph Display

The Graph View presents the data from a single row as a graph. The default display shows:

  • The Analysis Results column headings as the x-axis
  • The number of titles or holdings as the y-axis
  • The name of the row you selected as the graph title

You can view a graph by selecting the Display Graph Graph icon icon.

Change Analysis

The Change Analysis screen allows you to change the order in which analysis dimensions are applied to an existing analysis. You can:

  • Change the column value
  • Change the order in which analysis dimensions are applied as rows:

Limit Analysis

The Limit Analysis screen allows you to reduce the breadth of an analysis by specifying subsets of one or more analysis dimensions. This enables you to reduce the number of records retrieved and focus information for specific purposes.

You can select subsets of all dimensions. For the OCLC Conspectus, you can select Divisions only; you cannot select down to the level of Category or Subject.
