How to Contribute Records to SOLAR

Sending files

Initial Load

An export of MARC records, including information like barcode, call number, and count can be loaded into the Solar system. Note, however, that completeness and consistency is important in a database of records from many sources.  Large numbers of incomplete records can accumulate quickly if one is not careful.  Hence, records that lack basic data elements such as ISBN, LCCN, imprint and physical description will be skipped.  Other markers of poor cataloging practice will be used to determine which records will be loaded and which will remain for the local library to add interactively or provide in an improved form.

Update Methods

Even before initial loading, it is important to consider how you will keep your SOLAR information current. You should decide on one of the following before contributing records or beginning use of the system.

  1. Fully Interactive Method: Add and delete all records interactively, using software and training provided by the Maine InfoNet project.This method may be appropriate for libraries that have no local automated system. It may also appeal to libraries that put a premium in being able to make immediate changes in the database.(This method can be used even if the library has provided a file of records for initial loading.)

  2. Batch Adds Method: Send a complete file of records the first time, then in subsequent cycles send files containing only new titles.  The library is expected to handle deletions through direct, interactive use of database editing software provided by the Maine State Library.This method will make sense for libraries that have a manageable number of deletions and don't mind doing them interactively. It may also make sense for libraries with a backlog of records from a cataloging program but without a functioning automated library system. Each successive file of "Adds" must not duplicate records you have previously sent.

This method requires a unique barcode number in every record.  Barcodes must NOT be re-used.

Notes On SOLAR Operation

  • Incoming files are always compared to a mirror image of SOLAR, and then to a Library of Congress database.  In most cases, only your call number and a handful of other local data elements are moved to this record. The bibliographic description in your record will usually be replaced.  The only exception: records that can be identified as having the markers of  good quality standards based cataloging and are either older than the contents of our resource files or represent local or unique resources.
  • The database operates on the shared master record principle.  At the time of loading, the incoming record is sought in the database.  If a match is found, the best record based on encoding level is retained in the database, and the holdings information from the other record is moved over onto the master record.  This may sometimes mean that subject headings or notes in the record with the lower encoding level will not survive.
  • Very brief records and other records that cannot be successfully merged will not be loaded.  There is no assurance of 100% loading.
