User Population °Carnegie I—Research Extensive/ Hispanic Serving ° 15, 000 enrollment °Doctoral degrees in 5 colleges: Agriculture, Arts & Sciences, Business, Education, Engineering

Methodology: Data collection ° Apache server log extraction n n 7 two hour intervals over 3 month period Various times: am, pm, weekends ° Created Library IP address map ° Charted search locations by IP address: n n Campus (NMSU domain) Off campus (non-NMSU domain) Staff Zuhl & Branson public service areas
Methodology: Data treatment I °Text files imported to spreadsheet °Imported three columns only n IP address, Date/Time, Search Query °Mapped IP’s to library locations °Selected only unmediated, remote locations to review °Divided spreadsheet into 3 worksheets n All, Unmediated, Staff
Methodology: Data Treatment II Search_Code = TALL replaced with Search=Title Search_Code = JALL replaced with Search=Journal Title Search_Code = FT*& replaced with Search=Keyword Search_Code=NAME replaced with Search=Author Search_Code=SUBJECT replaced with Search=Subject Search_Code=CALL replaced with Search=Call Number %2 B = replaced with + %3 A = replaced with : %27 = replaced with ‘ %3 F = replaced with ? %2 C= replaced with , %22 = replaced with “

Data Analysis °After coding all discrete searches, we then re-coded those searches based on repair types.
Search Repair Levels °Word Repairs occur at word level °Concept Repairs involve the concept(s) searched. A concept is typically multi-word or a phrase. It can be multi-concept °Search Repairs show knowledge of search types or knowledge of formatting within search types
Word Level Repairs Spelling (WS) multi-meter multimeter 18 th eighteenth Plural/Singular (WP) duns dun groups group Capitalization (WC) Doll doll
Word Level Example °GETSearch_Arg=bertrand russel& Search=Keyword °GETSearch_Arg=bertrand russell& Search=Keyword °GET Search_Arg=raceism in unimployment &Search=Keyword & °GET Search_Arg=racism in imployment &Search=Keyword
Concept Level Repairs Punctuation: Add/drop city of ladies “city of ladies” christine pisan punctuation (CP) pisan, christine Broaden: Drop concept/word (CB) How to use a digital multimeters Pregnancy—week by week Pregnancy Change to another concept (CC) English Men & Manners in the Eighteenth Century 18 th Century British Women Decline and Fall of Rome Edward Gibbon Narrow: Add concept/word (CN) “puerto rico” “English” pizan city of ladies Rephrase (CR) English Society in the 18 th Century Daily Life in Eighteenth Century England Ireland travel Ireland guidebook
Concept Level Example ° GETSearch_Arg=Patton&Search=Keyword ° GETSearch_Arg=General Georgo Patton &Search =Keyword (CN) ° GETSearch_Arg=Leadership&Search=Subject (CC) ° GETSearch_Arg=Military Leadership& Search =Subject (CN, ST ° GETSearch_Arg=General Patton leadership& Search=Subject (CN) ° GETSearch_Arg=George Patton leadership& Search=Subject (CR) ° GETSearch_Arg=Leadership style of George Patton& Search=Subject (CR, CN)
Search Level Repairs Invert words/names (SI) Edward Gibbon, Edward Add/drop article (SA) A Doll House Switch search type (ST) A Doll House (Subject) A Doll House (Title) Limit search (SL) Home care home care (limited to specific library location or format or language, etc. ) tf 140 s 73 (Keyword) tf 140 s 73 (Call Number)
Search Level Example I ° GET Search_Arg=child abuse laws&Search=Keyword ° GET Search_Arg=child abuse laws& Search=Subject ° GET Search_Arg=Troy Boone&Search=Author ° GET Search_Arg=Boone, Troy&Search=Author ° GET Search_Arg=A Doll House&Search=Title ° GET Search_Arg=Doll House&Search=Title
Search Level Example II ° GET Search_Arg=Babylonian Mathematics and the Plimpton 322&Search= Keyword ° GET Search_Arg=Babylonian Mathematics and the Plimpton 322&Search= Subject ° GET Search_Arg=Babylonian Mathematics and the Plimpton 322&Search= Title … 2 minutes pass… ° ° GET Search_Arg=History of Babylonian Mathematics&Search=Title GET Search_Arg=History of Babylonian Mathematics&Search=Journal Title GET Search_Arg=History of Babylonian Mathematics&Search=Subject GET Search_Arg=History of Babylonian Mathematics& Search= Keyword
Preliminary findings: Search types °Although no specific search type emerges as an obvious favorite Keyword Subject Title 28% 19% 16% Jrnl Title 15% Author 10% Boolean 9% Call # 3% ° 44% of all searches are for known items (title, journal title, author & call number)
Preliminary findings: Word level repairs
Preliminary findings: Concept level repairs
Preliminary findings: Search level repairs
Preliminary findings: Overall repairs
Preliminary findings °Over 50% catalog uses are non-staff n n Unassisted user searches. ……………. 56% Staff/Mediated user searches………. . 44% °Higher incidence of concept level repairs than word and search level °Preferred repair strategy is to switch search types °High incidence of retyping exact search
Further study °Extend data collection time periods °Increase # of data collection sessions °Include different user population °Extend analysis to include n n n Length of time spent repairing search Search types leading to more repairs Number of repairs made per search
