English language subject headings in the catalog of the National Library of Israel Elhanan Adler elhanana@savion.huji.ac.il
Background • Subject retrieval at the NLI has traditionally been based on a classified catalog using a system which is a mixture of Dewey Classification, Scholem Classification (expansion of Dewey for Judaica), UDC and descriptive text (including many synonyms) • This system is unique to the NLI. Much effort was expended in its upkeep. • Most Israeli libraries use alphabetic subject headings (either LCSH or Hebrew) • The stacks of the NLI (closed) are arranged by inventory number. Reading rooms have unique shelving systems.
Examples of the current system 001.091.767.1(08) Knowledge (History, description, critical appraisal of intellectual activity in general) - Muslim, Islamic, Arab countries - Collections, congresses 616(01)(09)(P) Human pathology; Clinical medicine; Diseases; Illnesses - Works of historic value; Sources 296.52 Halakha and poseqim before Moshe ben Maimon (Maimonides), Geonic literature and responsa, tshuvot ha-geonim 296.562.22(42) Shabbat - Halakha - Eruv hatserot (eruv of courtyards), eruv tehumin (eruv of boundaries) - England, Great Britain E114(020.8) Yerushalayim, Jerusalem - History and description - Audiovisual treatment including video cassettes
The major problems • The system is not known or understood outside the Library • Today, most users of the NLI catalog are remote users • Other libraries cannot use this data in their cataloging • The NLI cannot make use of subject data from other libraries • High maintenance cost
The logical conclusion • The NLI should switch to a subject retrieval system understandable to all users, particularly remote users • A widely used system which does not require local development should be used • The system chosen should allow transfer of subject data to and from the NLI
Why LCSH? • Most widely used system in Israeli academic libraries • Most widely used system in academic libraries in the English speaking world • Scholars worldwide are familiar with the system • Use of LCSH will enable the NLI to receive and provide usable subject data
Why not Hebrew? • Creation of a Hebrew subject thesaurus for a large research library (even based on existing thesauri) is a major, expensive professional task and would take years • It is unlikely other Israeli academic libraries would adopt it (another unique system!) • It would not serve non-Hebrew speaking scholars (the Library has a universal mission) • But there is still a need for Hebrew subject access – particularly for the non-academic segment of the NLI’s local user community
Isn’t LCSH passé? • Calhoun report (2006): “Abandon the attempt to do comprehensive subject analysis manually with LCSH in favor of subject keywords; urge LC to dismantle LCSH” • But LC has decided to continue LCSH with some simplifications: “Following the Calhoun report, LC did an analysis and determined we would continue with pre-coordinated subject strings (and LCSH for the foreseeable future) complemented by social tagging when that becomes feasible in our firewall environment.” (communication from Barbara Tillett, Feb. 2010) • When change does come, presumably there will be LCSH based conversion tools • The NLI can lead Israeli libraries into future systems only if it starts out together with them
How do we get from here to there? • Matching NLI records against LC MARC database (to 2006) held by the MALMAD Consortium [after 2006 MALMAD ceased purchasing LC data and joined OCLC] • Matching NLI records against Israel ULI Union List records from LCSH-using libraries • Creating conversion tables from NLI classification to LCSH • 80+% of incoming data from major card conversion project (outsourced to Backstage Library Works) contains LCSH • Not uniform but… • “Quick and dirty” with ongoing cleanup procedures
Example of conversion table $$a296(07) = 650 $$aJudaism$$xStudy and teaching $$a296.01 = 650 $$aJudaism$$xBibliography $$a296.01(020.8) = 650 $$aJudaism$$xBibliography @@ 655 $$aAudio-visual $$a296.01(04) = 650 $$aJudaism$$xBibliography $$a296.01(05) = 650 $$aJudaism$$xBibliography$$vPeriodicals $$a296.01(06) = 650 $$aJudaism$$xBibliography$$xSocieties, etc. $$a296.01(07) = 650 $$aJudaism$$xBibliography$$xStudy and teaching $$a296.01(08) = 650 $$aJudaism$$xBibliography $$a296.01(09) = 650 $$aJudaism$$xBibliography$$xHistory $$a296.012[100] = 650 $$aJewish philosophy$$vBibliography @@ 650 $$aJewish philosophers$$vBibliography $$a296.012[400] = 650 $$aJewish linguists$$vBibliography $$a296.012[530] = 650 $$aJewish scientists$$vBibliography @@ 650 $$aPhysicists$$vBibliography $$a296.012[574] = 650 $$aJewish scientists$$vBibliography @@ 650 $$aBiologists$$vBibliography $$a296.012[800] = 650 $$aJewish authors$$vBibliography $$a296.012[933.09] = 650 $$aJewish historians$$vBibliography $$a296.014 = 650 $$aAnonyms and pseudonyms, Hebrew @@ 650 $$aAnonyms and pseudonyms, Jewish
Progress in 1.5 years • Jan. 2010 – 50,000 NLI records with LCSH • June 2010 – 500,000 NLI records with LCSH (over 50% of relevant records) • June 2011 – 1,127,000 NLI records with LCSH (over 90% of relevant records)
Authority control • NLI purchased the retrospective LCSH authority file (370,000 records) from LC • Set up as a separate ALEPH authority file controlling the NLIs subject headings • General policy – make minimal changes and only in the NLIs core collection areas (Judaica & Israel) • Add xrefs from more common (in Israel) term • Prefer Israeli standard term • Add specific terms (kosher and/or ‘kosher-style’) • Quantity of records being processed precluded going through SACO, etc.
Personal and corporate subjects • NLI already has 600 & 610 subjects – but in all 4 scripts, and usually without subdivision • English/romanized 600s and 610s are added when found but this is not a major goal of the current project • Inconsistent romanization (LC vs. Academy of the Hebrew Language) • Future linking of personal and corporate names in various scripts (a separate project) will improve cross-alphabet searching
Uniform title subjects • Follow standard Israeli usage: Uniform Headings in Judaica authority filee.g. Talmud Bavli and Talmud Yerushalmirather thanTalmud and Talmud Yerushalmi

Theological issues - Bible • Bible used for Jewish Bible (Tanakh) • Bible. O.T. changed to Bible • Bible. O.T. Apocrypha changed to Apocrypha • Bible.N.T. changed to stand-alone New Testament • Requires parallel series of subjects : … in the New Testament … $xNew Testament teaching etc.
Other theological issues • B.C./A.D. or B.C.E./C.E.? • Personal subjects: Jesus, Mary, Muhammad, saints, etc.
Political issues: Israel/Palestine • LC policy: • Israel = 1948/1967 borders • Pre-1948 = Palestine • Post-1948 area of British mandate (Israel + West Bank) = Palestine • Palestine not to be used for post-Oslo Palestinian Authority • “680 __ |i Here are entered works on the region on the eastern coast of the Mediterranean Sea that in ancient times was called the Land of Canaan, later the kingdoms of Israel and Judah, and in modern times comprises the entire state of Israel, as well as the various disputed territories. Works on a specific jurisdiction or territory within this region are entered under its respective name”
Existing Israeli solutions • Follow LC • Israel for all periods and all borders (just as Persia = Iran) • Israel (State) vs. Israel • Israel and Eretz Israel (NLI choice) • Problems distinguishing between periods and geographic boundaries • Antiquities • Geography, geology, etc. • Overlapping periods (20th century)
Other geo-political issues • West Bank or “Judea and Samaria” • Jerusalem (Israel) • -- Israel -- Jerusalem • Nablus or Shechem (and other multiple place name issues)
Historical subjects • Israel – History -- War of Independence, 1948-1949not: Israel-Arab War, 1948-1949 • Six Day War, 1967not: Israel-Arab War, 1967 • Yom Kippur War, 1973not: Israel-Arab War, 1973 • Operation Peace for Galilee, 1982-1985not: Lebanon -- History -- Israeli intervention, 1982-1985
Uniquely Israeli topics • Immigrant absorption • Pre-army yeshivot • Yeshivot hesder • Bagrut examinations (Matriculation examinations) • Aliyah/Yeridah (much more than Emigration and immigration), also: • Aliyah, 1st (1882-1903) • Aliyah, 2nd (1904-1914) • Aliyah, 3rd (1919-1923) • Aliyah, 4th (1924-1929) • Aliyah, 5th (1929-1939) • Aliyah Bet (1933-1948)
Extension/expansion of LCSH terms • Judaism – [Moroccan, Tunisian, etc.] rite • [subject] (Jewish law) • Chronological subdivisions under Hasidism, Cabala, Jewish philosophy, etc. • More groups of Hasidim

Problem of subjects which require Jewish + general subject • Jewish … education • Jewish scientists + Physicists, etc.
Standard 667 (internal) notes • Changed to standard Israeli form • Cross references added by NLI • Heading created by NLI • Heading changed by NLI
Use of Genre/Form headings • Primarily in conversion from Dewey literature numbers • 655_7 with $2local • Example: • Polish drama • Polish essays • Polish fiction • Polish letters • Polish poetry • Polish prose literature • Polish wit and humor • Also: Audio-visual, Israeli themes in literature, Jewish themes in literature
Ongoing cleanup • Create initial files of valid main terms ($a) and subfields (vxyz) from LC LCSH file • Add terms & subfields as validated • Run test against all 630/650/651 2nd indicator 0/4 (existing records and new records being added) • Report errors & automatically fix many • Group of programs and data files
