Spectra CRC In the Press“Library Dynamics . . .has developed the most impressive data-analysis product I saw in the exhibits.
The product analyzes and compares collections for decision support more deeply and thoroughly than any other collection analysis product I have seen. … I am convinced that an all purpose data-mining product has significant limitations, because no generic tool can serve all analytic needs well.
The best products are those that are tailored for very specific types of analysis, because each kind of data analysis requires its own software.
The deeper the developer's understanding of the type of analysis being attempted, the better the product will be. “

Times Up, So?
• These two displays contain the same sample data based on title counts from
– Bryn Mawr, – Haverford, – Swarthmore– the 1st 25 years of titles reviewed in Choice.
• Do either of these presentations stimulate your interest to explore a bit further?
The basics
• Four Levels of Analysis– Library Wide – 22 Categories
– Intermediate –250 Categories
– Precision Level – 6,000 Categories
– Title Level – Full MARC Bibliographic Record• Links to related material (related subject, etc.)
• Links to reviews
• Links to pricing and ordering sources
A funny thing happened on the way to Multi-Library Multi-Source Analysis
• Title Count• % Overlap• % Unique in Base Library• % Unique in Comparison
Library or Source• # of Titles by Publication Date• Title Frequency
• Title Count• % Overlap• % of Uniqueness• Overlap Concentration • Gap Analysis• # of Titles by Publication Date• Title Frequency• Copies / Use Plot• Annualized Use Plot• Annualized Use per Title Plot• Zero Circulation Plot• Uses per Publication Date Plot
Title Count ComparisonCompare visually the numbers of titles in the base & up to 11 other libraries or sources
Immediately grasp the overall size and subject composition of the libraries.
Interact directly with the data clicking on a point to display the category name, the library, library group or source name, and the number of titles in that category.
Facilitate the work of a single individual or a team to drive the analysis most efficiently, concentrating on the signal and not the noise.
Copy, export, past tabular data supporting the graphic analysis easily for further analysis.
Percent of Overlap
Visualize the % (degree) of title overlap of each comparison library or source
Get an immediate sense of overall overlap as well as overlap in broad subject areas
Focus quickly on congruence or divergence in a number of broad subject areas
Test the relative fit of the comparative libraries or sources with the base library
Identify an outlying comparison library or source
Percent of Uniqueness
Visualize the % (degree) of uniqueness of each comparison library or source
Get an immediate sense of overall uniqueness and uniqueness in broad subject areas
Focus quickly on congruence or divergence in a number of broad subject areas
Test the relative fit of the comparative libraries or sources with the base library
Identify an outlying comparison library or source
Overlap Concentration
Concentrate not on individual libraries/sources but the degree to which libraries/source overlap within each subject area (x% of titles in an interval held by y libraries/sources)
Visualize within subject areas degree of overlap between and among all being compared
Focus quickly on areas of high title overlap in individual subject areas
Identify whether the libraries/sources being compared have any common titles
Gap Analysis
Concentrate on the number of titles which 1, 2, 3, or 4 libraries/sources have in common which your library or library consortium lacks
Visualize these gaps across the entire library and in successively more precise subject intervals
Focus quickly on those areas where your library/consortia differs most substantially from the comparison group
Number of Titles by Publication Date
Visualize the relative collection age among all libraries and sources.
See the collection age of the entire collection as a whole at the top level.
See the collection age of increasingly smaller collection subsets at 2nd and 3rd levels.
Annualized Use AnalysisView use as you define it - circulation, in house use, reserves, electronic reserves, & ILL
Learn how combining bibliographic and use information matters
View normalized use for each subject area per the number of years of availability
Grasp the meaning of calculating and summarizing use in each interval by dividing each title’s use by the number of years of the title’s availability
Visualize use across the entire library and within progressively narrower subject intervals
Focus quickly on areas of high title overlap in individual subject areas
Copies versus Use
Conduct this analysis at the second and third tier of Spectra CRC Analysis
Examine the relationship between numbers of copies (supply) and use (demand)
See a scatter plot for a selected interval of each title’s number of copies and aggregate use
Correlate cases of zero use, moderate use, and high use with number of available copies
Use a lasso to select the cases of interest and view the corresponding titles.
Function in place. Currently testing the functionality.
Annualized Use per Title
View use as you define it
View annualized use averaged for each subject interval per title within the interval
Visualize how taking into account the number of titles in each interval accounts for the differential size of collections in each interval
Visualize use across the entire library and within progressively narrower subject intervals
Zero Use Plot
Compare the percentage of titles which have zero (0) use (Y axis) in each category (X axis).
The user may select a point on the line plot and drilldown either to the next level of the subject hierarchy or to a Title List.
Function in place. Currently testing the functionality.
Uses per Publication Date
Visualize counts of use by the publication date of the title
Determine usage patterns for the entire library or subsets of the library
Title Frequency
Concentrate on the relationship among the number of titles held uniquely by each library and the number of titles held by two or more libraries
Visualize your library in terms of its share of the unique titles

Remember that first analysis? Title Count comparison by class?
NEW! Library Dynamics North American Title Count Program
NATCP provides
• title counts by subject category (only one of the analyses provided by Spectra CRC)
• relative strengths of collections based on the number of titles
• reports on 700 broad and mid-level call number ranges
• data from NATCP participating libraries.
Library Dynamics North American Title Count Program does not
• does not allow comparisons beyond the 700 categories
• does not allow comparisons at the title level
• does not include use analysis data or bibliographic source comparisons
• does not provide graphical charts and displays
What is it?
• Library Dynamics North American Title Count Program is a statistical product providing title counts of holdings data in participating library collections in North America.
NEW! Library Dynamics North American Title Count Program (NATCP)
Why is it important?Since 1973 an ALCTS Division of ALA sponsored a NATC program every four years
Title counts in 688 LC Classes.
A basis for collection assessment and comparison based on collection size for participating libraries and others.
Why Library Dynamics?The last NATC was carried out in 2001. Since 2001 ALCTS has refocused its overall program, decided to deploy its financial resources differently in a number of areas, and decided not to undertake the 2005 NATC.
Former NATC participants approached Library Dynamics to outline their needs
It was in the process of working with Spectra CRC clients that the concept of a Library Dynamics NATC evolved.
In addition to making a large title count comparison possible, the library database or “shelflist” data would enhance the functionality of Spectra CRC subscribers by providing a larger comparison base.
NEW! Library Dynamics North American Title Count
How is it Better?
In the past, participants committed large blocks of time to fill out data survey forms.
Library Dynamics receives participant databases (“shelflists”) electronically via ftp
Analyzes the data
Receives updates from the participants and analyzes the data annually
A process in which:
• You send us your shelf list.
• Library Dynamics does the counting.
• Your access is online.
What’s the Difference?
Library Dynamics Spectra CRC
provides in-depth, overview-to-title-level collection analysis capabilities, for both holdings and use data, complete with dynamic graphic visualization for communication of results.
Library Dynamics NATC
is a statistical title-count only comparative program, historically provided by the North American Title Count (NATC)
