Thanks Frederic, Here are a set of 10 records from the marc import file. The barcode/accession number is the one corresponding to 950 (for example in record 1: "=950 \\$a21193" and =950 \\$a4813) Corresponding to 950a in the database i added the items.barcode field in the "marc_subfield_structure" table. ---------------------------------------------------------------------------------------- =LDR 00333nam 2200169Ia 45e0 =005 120604 =004 D =005 M =010 65-16401 =100 \\$aAndrews$bDonald H. =100 \\$aKokes$bRichard J. =245 \\$aFundamental <Chemistry> =250 2nd ed. =260 \\$aNew York$bJohn Wiley$c1965 =950 \\$a21193 =950 \\$a4813 =952 \\$a540ANDK ---------------------------------------------------------------------------------------- =LDR 00268nam 2200121Ia 45e0 =020 0-06-040805-7 =952 \\$a540BOIE =100 \\$aBoikess$bRobert S. =100 \\$aEdelson$bEdward =245 \\$a<Chemical Principles> =250 3rd Ed. =260 \\$aNew York$bHarper & Row$c1985 =950 \\$a30262 ---------------------------------------------------------------------------------------- =LDR 00311nam 2200145Ia 45e0 =010 84-10798 =020 0-06-040805-7 =100 \\$aBoikess$bRobert S. =100 \\$aEdelson$bEdward =245 \\$a<Chemical principles> =250 2nd Ed. =260 \\$aNew York$bHarper & Row$c1982 =950 \\$a28407 =950 \\$a29531 =952 \\$a540BOIE ---------------------------------------------------------------------------------------- =LDR 00347nam 2200169Ia 45e0 =010 74-10192 =020 0-12-132372-2 =100 \\$aBrescia =100 \\$aArents =100 \\$aMeislich =100 \\$aTurk =245 \\$aFundamentals Of <Chemistry> =250 3rd Ed. =260 \\$aNew York$bAcademic Press$c1975 =650 \\$aChemistry =950 \\$a8567 =952 \\$a540BRE ---------------------------------------------------------------------------------------- =LDR 00278nam 2200121Ia 45e0 =020 0-333-444-97-3 =020 0-333-37310-3 =100 \\$aFreemantle$bMichael =245 \\$a<Chemistry> in Action =260 \\$aLondon$bMacmillan Education Ltd$c1987 =650 \\$aChemistry =950 \\$a34810 =952 \\$a540FRE ---------------------------------------------------------------------------------------- =LDR 00192nam 2200085Ia 45e0 =100 \\$aAndrews$bDonald H. =245 \\$a<Chemistry> - Humanistic view =260 \\$aTokyo$bMcGrawHill$c1974 =950 \\$a20610 =952 \\$a540AND ---------------------------------------------------------------------------------------- =LDR 00220nam 2200097Ia 45e0 =100 \\$aBabor$bJoseph A. =100 \\$aLehrman$bAlexander =245 \\$aGeneral <College Chemistry> =260 \\$bThomas Crowell$c1947 =950 \\$a3260 =952 \\$a540BABL ---------------------------------------------------------------------------------------- =LDR 00233nam 2200097Ia 45e0 =100 \\$aBarton$bL. =245 \\$aNew trends in Chemistry =260 \\$aBerlin$bSpringer-verlag$c1982 =440 \\$aTopics in current Chemistry$v100 =950 \\$a24630 =952 \\$a540BAR ---------------------------------------------------------------------------------------- =LDR 00241nam 2200109Ia 45e0 =100 \\$aBaum$bStuart J. =100 \\$aScaife$bCharles W. =245 \\$aChemistry, <Life Science> Approach =250 2nd Ed. =260 \\$bMacMillan$c1980 =950 \\$a8335 =952 \\$a540BAUS ---------------------------------------------------------------------------------------- =LDR 00217nam 2200097Ia 45e0 =100 \\$aBresica =245 \\$a<Students Guide> To <Fundamentals> Of <Chemistry> =250 3rd Ed. =260 \\$bAcademic Press$c1975 =950 \\$a8568 =952 \\$a540BRA ---------------------------------------------------------------------------------------- Please let me know if some more details would me needed.
