  • Other collection uses can be done by requesting known items, changing the location of browsing across many titles – it will be done at the pick-up desk rather than at the shelf.

    5. 5. Collection Locations Pre-Renovation • Penrose Library • Built in 1972 • PASCAL • Shared storage facility with University of Colorado System • Campus storage (Mary Reed Building) • Music Library • Law Library
    6. 6. Collection Size – Linear Feet Penrose, 108,502 Mary Reed, 3,187 PASCAL, 27,397
    7. 7. Collection Locations Post-Renovation • Anderson Academic Commons • (The renovated, renamed Penrose Library) • Hampden Center • High-density storage • 10 miles from campus • 3-hour delivery
    8. 8. The Initial Plan (until Spring 2011) • Renovated library • 75% of monographs • Excluding monographs with 0 circulations (post-1997) published before • 1950 (humanities) • 1980-2000 (social sciences, science, technology) • 10% of serials (mostly image-heavy) • New storage facility • 25% of monographs • 90% of serials • 100% of government documents • 100% of microforms • 95% of boxed archival collections
    9. 9. The Big Picture (original plan) Upper level • 25000 sf of books • Perimeter seating Main level • All services and seating • Staff areas Lower level • 25000 sf of books • Some seating Upper level • Seating and staff areas Main level • Seating and service points Lower level • 15K – 20K sf of Collections • Seating Pre-renovation After completion
    10. 10. The Big Picture Upper level • 25000 sf of books • Perimeter seating Main level • All services and seating • Staff areas Lower level • 25000 sf of books • Some seating Upper level • Seating and staff areas Main level • Seating and service points Lower level • 15K – 20K sf of Collections • Seating Pre-renovation After completion
    11. 11. The Library Plan, or How Do You Plan for 20% •Assumptions: • Need recognizable rules • Provide collections for all disciplines • Take usage into account • Require minimal maintenance
    12. 12. Library Recommendation (20%) •Core collection: • Imprint date of 2003 and later in most disciplines • Except those available as e-books. • Five or more circulations since 1997, any imprint date • 2900 LF of the art and art history books and journals • Total: 19,900 LF
    13. 13. A Faculty Committee Charge: to make a data-driven decision about the right mix of seating and collections on the lower level of the renovated library. Representatives from (mostly) humanities and social sciences.
    14. 14. The questions: • What is the purpose of an on-campus collection? • What criteria should be used to shape an on- campus collection? • (Why) should it be larger than 20% of the monographs proposed by the Chancellor and the Board? • Which data should be considered in supporting recommendations?

    30. 30. On-Site Collection Goals? • A starting point for undergraduate research papers • Serendipitous discovery (browsing) that will result in some material • Immediate access for people who can’t wait to get something • Something for everyone across all disciplines, supporting teaching • Something for heaviest users: AHSS • Material to support research when only browsing works
    31. 31. THE SURVEY
    32. 32. Faculty: why do you visit the print collection? • Two dominant browsing patterns for faculty: • A known item search, then find additional material on the shelf • Go directly to “your” shelf location to browse for materials • In addition, it is common (48%) for faculty members to visit in order to look up something specific in a specific title.
    33. 33. Students: Why do you go to the stacks? • 14% do not use the print collection • 6% always use Request It • 67% browse for a course assignment • 44% browse for creative inspiration • 74% are going after a specific book • 41% need to look up a fact or passage in a book • 13% described other reasons • Look for one book and find a lot of others • Reading for pleasure • Personal reading • Practicing language skills • To relax
    34. 34. Faculty: collection use for research • 65% say books are primary research resources. • 68% use books to find specific information • 66% use books to update or refresh knowledge and 80% use books to expand knowledge • Comments illustrate very high levels of concern about these modes of inquiry becoming so inconvenient that inquiry itself will be disrupted, reduced, or even impossible.
    35. 35. How many Linear Feet for assignments? • Clearly, all books in each call number would not be needed, but that’s how we counted. • We did not include responses such as “all collections” or “all literature.” • We added up linear feet for topics specified by respondents. • All areas of the collection are used in teaching. 73,000 LF
    36. 36. Faculty: What (specifically) should be returned to the new library? 70,041 LF • Responses range from “everything” to “all literary criticism” to works by a specific author. • Many responses show the extent to which teaching and research is interdisciplinary: gender studies, race studies, multicultural therapy, history of literacy, or church/art/social history. • We excluded responses such as “all collections” or “all literature.”
    37. 37. Faculty: when is a 3-hour delivery OK (i.e. what can be stored?) • Some respondents said there is nothing for which a 3 hour delivery time is OK; it diminishes browsing. • 49% said we could store anything that had never been checked out. • 49% said low use books were OK to store. • 60% approve storing the paper version of an e-book. • 34% thought we could store the book if the catalog record includes a table of contents online.
    38. 38. Key concepts from comments • For some students and faculty little concern about storing collections. HOWEVER • The vast majority of respondents, both students and faculty, very unhappy, worried, angry, upset, or concerned about the decision to store most of the book collections. • Few worry about turnaround time; most regret loss of browsing.
    39. 39. Key concepts • Some collection uses CANNOT be done by requesting known items. Examples from the survey are: • Image/photo/illustration searching within books (hence our recommendation that we return the art books) • Assessment of degree of difficulty of non-English Language fiction • Choosing older volumes on the basis of presentation (font, format)
    40. 40. THE DISCUSSION
    41. 41. What would a subject collection look like? Discipline Titles Linear Feet Arts & Humanities 439,466 37,290 Cookbooks 7,432 531 Business 36,340 3,028 General 14,873 963 Mathematics 23,497 2,937 Education 50,465 3,509 Natural Sciences 89,738 7,474 Engineering, Computer Science 29,850 2,723 Social Sciences 214,376 17,446 Totals 906,037 75,901 % of Collection 49.1% 0.7% 4.0% 1.3% 3.9% 4.6% 9.8% 3.6% 23.0%
    42. 42. 50% Scenario • Would accommodate 39,500 LF • Subtracting the core collection of 19,900 leaves 19,600 for flexible collections. • Seating loss (compared to the 30% scenario) of about 120 seats. • Which 19,600 LF? What data support this scenario?
    43. 43. Data Points • 80% of circulation = books published in last 30 years • 40% of recent books will circulate 2 or more times • Users of visually-heavy material (especially art history) browse in ways that other disciplines don’t
    44. 44. Recommendation • Books published since 1983, excluding e-books, duplicates, older editions 32,000 LF • Books published before 1983, checked out 2 or more times 4,419 LF • Heavily-illustrated materials, excluding the above two categories 3,000 LF • Total size of on-site collection 39,419 LF • Percentage 50%
    45. 45. 1972 2013
    46. 46. • Finite space, tightly packed • Code records for storage based on criteria • Allows for shifting when needed MANAGING A SMALLER LOCAL COLLECTION
    47. 47. iCode Disposition Action 0 Needs evaluation Periodic review based on criteria 10 Storage Can be stored when needed 12 Academic Commons, but needs review for ebook, edition (could move to storage) Check for ebook availability, newer editions 20 Academic Commons Review on broad criteria (age, circulation) 29 New Book Area Can move to 10, 12, 20 EVERY BOOK IN ITS PLACE
    48. 48. • Easy: When it’s time to shift, search for iCode 10 • Fast: Allows staff to quickly meet space needs • Policy-Driven: Based on established criteria • Flexible: Code and note can be revised based on faculty or selector input PRE-CODING ALLOWS FOR EFFICIENT STACKS MANAGEMENT
