I've had very good luck using DBM files to store, sort, and retrieve MARC records. This effectively eliminates the RAM issue, since DBM files retrieve only the hash elements from memory that are needed, and so don't burden RAM. (See Chapter 16, "Simple Databases", of "Learning Perl" by Schwartz and Phoenix for a good write-up about using DBM files.) -- Chris Morgan
