BHL Ingest Criteria Review

Summary for the IC

Collections & Ingest Committee: Bianca Lipscomb, Don Wheeler, Grace Duke, Suzanne Pilsk, Connie Rinaldo, Christine Giannoni, Becky Morin, Judy Warnement, Matt Person
The ongoing ingest of IA “non-biodiversity” collections, i.e. materials brought in as a result of non-BHL member scanning, has resulted in the acquisition of both relevant and irrelevant materials. The BHL Collections Committee has reviewed some of these materials and has identified the following examples of irrelevant content:

Irrelevant Material	Suspected Ingest Criterion	Recommendation
Materials ingested from the Joint Committee on Taxation ~ 70+ titles	gov't doc nos. in 099 field read as LC call nos. for Agriculture ex. "S. Prt. Vol. 674-0007"	Do not match to call nos. in 099 field
Validation of ice skating protocol to predict aerobic power in hockey players / by Nicholas J. Petrella.	Respiration as subject heading	"Respiration" irrelevant term, remove from Ingest Criteria
A measure of meter conservation in music, based on Piaget's theory / by Mary Louise Serafine.	"S483m" in 099 read as LC call no. for Agriculture	Do not match to call nos. in 099 field
Keeping the body in health, by M. V. O'Shea and J. H. Kellogg	Physiology as subject heading	"Physiology" too broad a term, remove from Ingest Criteria
An abridgment of the hygienic physiology : with special reference to alcoholic drinks and narcotics. For the use of junior classes and common schools / by Joel Dorman Steele.	Physiology as subject heading	"Physiology" too broad a term, remove from Ingest Criteria

More examples: Relevance and Collections

There is a need to review the Ingest Criteria, a series of LCSH terms and call nos. used to match against the IA corpus, and refine the list to include only those terms and call nos. that yield the highest return of relevant content. The Committee has implemented 4 strategies for review:

Relevant Files for Review

1. IAAnalysisSubjectsAndCategories.xls (ca. November 2009)
   1. Sheet 1: List of LCSH ‘650 a’ used as part of Ingest Criteria; List of LCSH ‘650 v/x’ used to exclude certain titles from the Ingest; List of LC call nos. used as part of the Ingest Criteria
   2. Sheet 2: Combined list of…
      1. BHL LCSH 650s (= “BHL” in ‘desrip’ column; ‘Notes’ column indicates where term is 650 z) and counts indicating how often these terms occur in the BHL collection
      2. LCSH ‘650 a’ terms used as part of Ingest Criteria (= “used” in descrip column)
2. Subjects in BHL - 2010-04-16.xls
   1. Sheet 1 = BHL Member Subjects – list of all 650 a LCSH which occur 5 or more times in the BHL collection for BHL member contributed titles only
   2. Sheet 2 = Non-BHL Member Subjects – list of all 650 a LCSH which occur 5 or more times in the BHL collection for Ingested titles only
   3. Sheet 3 = Combined List – lists from Sheet 1 and 2 combined with the list of 650 a terms used as part of the Ingest Criteria (see also above)

Review BHL Terms [Don, Matt]

• Look at the list of BHL subject keywords, derived from the ‘650 a’, and identify terms that are:
  • “IN” – LSCH terms that we want to match against the ‘650 a’s for “non-biodiversity” titles in the IA corpus
  • “OUT” – LSCH terms that, while relevant to biodiversity, we will not use because they are too broad in scope and result in a questionable ROI for the BHL collection.
    • For example: BHL should NOT include the LCSH terms “Physiology” and “Reproduction” as part of the Ingest Criteria
  • Note: To be on the safe side, Suzanne and I found that it was better to recommend exact LCSH terms and not wildcard-ed terms like “Bears*” (pulls “Bears on postage stamps”…[yes, a real LCSH]) or “*Ecology” (pulls Gynecology).

Identify Good Ingest Terms [Connie, Judy]

• What terms are we bringing in as a result of the Ingest completed to date that are NOT already BHL terms and would be good additions to the Ingest Criteria?
  • “Wilderness areas” and “Wildlife management” for example

Identify Bad Ingest Terms [Christine, Grace]

• What terms are we bringing in as a result of the Ingest completed to date that are LCSH terms that we absolutely do not want as part of our criteria? This is an ALL OR NOTHING approach -- these terms would override any other terms also associated with the record.
  • For example: BHL should exclude all records with the LCSH term = “God” from the Ingest pool.

Call nos. [Suzanne, Becky]

• What are the MARC tags, subfields, and indicators that we want to use for the Ingest Criteria? Suggested (indicators unknown):
  • 050 a
  • 090 a
  • 082 a
  • 092 a
  • 852 j/h
  • 099
• What Dewey nos. do we want to use? Dewey Analysis - BHL Member Libraries.xls
  • Decision: Match Deweys to LC subclasses below
• Should/How can we refine the list of LC call nos. we are currently using as part of our Ingest Criteria?
  • GC (Oceanograpy)
  • Q [no other letter] (general science) -- Need to refine?!
  • QH (natural history)
  • QK (botany)
  • QL (zoology)
  • QR (microbiology) -- Do we want this one? - lipscombb May 10, 2010
  • S [no other letter] (agriculture) -- Need to refine?!
  • SB (plant culture)
  • SD (forestry)
  • SF (animal culture)
  • SH (fisheries and related)
  • QE 700-999 (Paleontology) -- All QE NOT relevant

Review Excluded subject subdivisions [any volunteers?]

• Are there additional subdivisions that we want to exclude? – REMEMBER: the ALL OR NOTHING approach applies here too
• Are there any subdivisions that we would always want regardless of the ‘650 a’? Would it ever be the case that one of these subdivisions would NOT have a ‘650 a’ that’s already part of our criteria?
  • For ex.: v “Pre-Linnean”
