The quality of the records in the CZ is determined by the type of records sent to Ex Libris by the vendor. Record quality can vary, and may be enhanced over time as vendors send updates. For example, a brief bib may be replaced by the vendor's full bib.
There are several options for dealing with brief or insufficient bib records from the CZ. However, if the record is not completely unusable, it might not be worth the time and effort to correct it, and might be better to wait for a vendor update.
Potential Drawbacks to modifying insufficient bib records:
If the community zone portfolio you would like to use is linked to an undesirable record, but there is another better bibliographic record available in the CZ, you can relink that portfolio to the better CZ record. This method requires no ongoing maintenance on your part.
You can convert a CZ bibliographic record into a local IZ record and edit it as much as you'd like. This may be a good option if there is not a better CZ record to use, and the existing CZ bib record is a good starting point. The drawback to this method is that you will no longer inherit any CZ changes for this bib record.
Importing a record directly into your IZ from OCLC is another option if you feel you need a better bibliographic record for a portfolio.
Repository Import Profiles may be used to load or update records and inventory from external sources like publishers or OCLC Collection Manager. You may use them for individual records or sets of records.
