Dear Colleagues, We are planning to set up a major database of rare books of several Hungarian libraries. So far the general practice among the libraries was either to create a separate bib. record for all copies of a publication or create one bib. record, enter copy specific notes on various copies and to try to separated them with the help of subfield $5. Something like the following: 001 bibJAT00008399 # 005 20031128161552.0# 008 960719s1681 lat d# 040 $dHuDeKLEK# 080 $a094.1(439)"1681"# 100 1 $aBâarsony Gy?orgy$c(Lovasberâenyi)$d(1626-1678)# 245 10 $aVeritas toti mundo declarata; sacram caesaream regiâamque majestatem non obligari ad tolerandos in Ungaria Lutheranos, et Calvinistas /$cauthore ...Georgio Barsony# 260 $a[Nagyszombat] :$bTyp.

In a database of several libraries it seems to be a necessary step. This way, however, we seem to be unable to create all those name headings that belong to copy specific data now in the item record. Is it necessary to sacrifice the uniform names of possessors if we want the more coherent structure of bibliographic and item records?

Is it a totally impossible idea to add name headings to holding/item records? (The system we are going to use might be able to cope with this idea.) It seems to make more sense then leaving the heading in the bib. record. I would be very much interesed in your opinion and advice. Thank you very much Klara Koltay Debrecen University Library
