Perceptions of libraries, 2010 “Whencomparinglibrariestosearchengines,overwhelmingly,Americansconsidersearchenginestobemoreconvenient,faster,morereliableandeasier‐to‐use.Americansconsiderlibrariestobemoretrustworthyandmoreaccurate.
WhileAmericansrankedlibrariesaheadofsearchenginesintrustworthinessandaccuracy,thisdisDncDonevaporateswhenaskedabouttheinforma(onthatisprovidedbysearchenginesandlibraries.MostAmericans(69%)believetheinformaDontheyfindusingsearchenginesisjustastrustworthyastheywouldfindfromtheirlibrary.”

Next generation discovery services Commercial• AquaBrowserLibrary• BiblioCommons
• EbscoDiscoveryServices• Encore(InnovaDveInterfaces)• PrimoCentral(ExLibris)
• SirsiDynixEnterprise• Summon(SerialsSoluDons)
• Visualizer(VTLS)• WorldCatLocal(OCLC)
Opensource• Blacklight• Fac‐Back‐OPAC(Kochief)• LibraryFind• Rapi• Scriblio(WPopac)
• SOPAC(SocialOpac)• VuFind(Breeding,2010;Yang&Wagner,2010)
Desired features of discovery services • Singlesearch/pointofentry− foralllibrarymaterials
• State‐of‐the‐artwebinterface• Enrichedcontent
e.g.bookcoverimages,userinput
• FacetednavigaDonofresultse.g.dates,formats,locaDon
• Simplekeywordsearchbox− oneverypage
• Relevancyrankinge.g.influencedbycirculaDondata
• Didyoumean...?− spell‐checkingmechanism
• RecommendaDons
• UsercontribuDonse.g.summaries,reviews,raDng,tagging,folksonomies
• RSSfeeds• IntegraDonwithsocial
networkingsites
• Persistentlinks(Yang&Wagner,2010)
Web scale discovery – the story so far • Combiningnext‐generaDoncatalogueswithfederatedsearch− integraDngprintanddigital,localandremote,recordsandcontent
• Providingaccesstolibraryresourceswithinuserworkflows− searchfromlibraryhomepage,LibGuide,uniportal,Blackboard,etc
• AllowinglibrariestocreatemulDpleprofilesforcommuniDes− subjectsubsetsofdiscoveryresourcestoavoidoverwhelmingusers
• EarlyreportsofdramaDcimpactonuseoflicensedresources− studentsabletofindthingseasily,butnotabletointerpretresults
• ImplicaDonsforinformaDonliteracyandreferencesupport− fromdatabasesearchingtounderstandingandevaluaDnginformaDon
