Hi folks, While working on a project that frequently requires that we find out various low-level facts about our MARC records (e.g. "How many records do we have with 510 fields where indicator1 = '1'?"), we ended up writing a small, unsophisticated, but so-far useful tool for extracting those records into a Solr index. All you need to run it on a machine is a Java Development Kit (JDK), Apache Solr, and files containing the MARC records you want to query. See the README for more details if you're interested: https://github.com/NCSU-Libraries/dsci cheers, AC
