Pasted statements are enough to work out patterns. Converting a file needs the file itself.
MARC Serials Toolkit v0.6.0
Proof of concept — under active development. Check your output before loading it into the catalog.

Three tools for MARC serials holdings. The Holdings Workbench finds the patterns in your 866 statements, asks you to confirm what each part of a pattern means, and converts using them. The Converter turns textual 866 holdings statements into structured 853 caption/pattern and 863 enumeration/chronology fields. The Pattern Detector groups free-text holdings by their structure and generates a matching regular expression for each group.
