Methodology for Creation of Records

Donna Rosinski graciously shared with us Cassidy's thorough process: "When we start a project at Cassidy, Joni and the catalogers build records from scratch to make sure that we cover all bases. When we start a project after developing the initial template, if we have records for direct equivalents in other formats, we do use those records as guides for the new records, but we are careful to follow our template for the new format/project. After the records are created, they are proofed by a cataloger other than the one who initially created the record to help catch any proofing errors that the original cataloger may have missed."


"For the Westlaw and LexisNexis records, we are using print equivalent records as a basis for the electronic resource records, but we do have to create some records from scratch." 



Customization available, some for no additional charge. 



Review Status

All records available as of May 20 2008 have been reviewed.  


Authority Control

All records are sent for automatic authority control, so the headings are generally in good shape. The only headings that may appear in an unauthorized form are name headings that cannot be validated by machine. Example:  


Name in record: Gonzales, Ervin
Authority record: 
001     n 2002119372

003     DLC

005     20030116071903.0

008     030116n| acannaabn          |n aaa

010     n 2002119372

040     DLC|beng|cDLC

100 1   Gonzalez, Ervin A

670     Florida civil trial preparation, c2002:|bp. iv (Ervin A. Gonzalez; 1985 grad. cum laude of the Univ. of Miami Sch. of Law)

Since there is no 400 field with Gonzales, Ervin, there is nothing to re-direct the system to the correct form of the heading. Cassidy does not control headings manually, so it is up to the individual libraries to make the necessary corrections. 


Fixed Fields

All seem correct. All records have 006 and 007 fields for electronic format.   


Variable-Length Fields

Records include all required fields.


Most records have 530 notes for the print version, but very few have a corresponding 776 field (keep in mind, however, that 776 field is OPTIONAL).


WESTLAW COLLECTION IVrecords for this collection of law journals and law reviews were cataloged as integrating resources and describe Westlaw as the publisher, departing from the CONSER-recommended aggregator-neutral record. Here are the descriptive fields from Cassidy's record for Yale law journal on Westlaw:

Subject Headings/Classification 

All records have valid LC Subject Headings. A few invalid subdivisions were found and forwarded to Cassidy, who assured us that the headings will be corrected. 


Records do not include LC Classification numbers. 




WESTLAW COLLECTION III: archived state codes (mostly annuals) were cataloged as monographs.  In most cases this could have been avoided since Westlaw often provides access to the historical materials from a link on the front page for each archived title with links to the individual volumes. 


WESTLAW COLLECTION IV: for those who already have records for HeinOnline journals and are concerned about duplication of records for electronic titles, note that by May 2008 (with approx. 80% of the Westlaw IV collection cataloged), 66% of the Westlaw IV titles were also available on HeinOnline. 


LEXIS/NEXIS COLLECTION II: archived federal and state codes and administrative codes (mostly annuals) were cataloged as monographs, resulting in 887 records for 103 titles. In most cases this could have been avoided since Lexis often has a front page for each archived title with links to the individual volumes. For a list of these titles see the following Excel file (note that the file includes FIVE tabs for Lexis 2.1, 2.2, 2.3, 2.4 and a combined list): cassidy_lexis_2.xls  




Additional Comments 

ym (5/14/08): Although we do not always see eye to eye on how to catalog certain materials, I know that Cassidy staff reach their decisions after much deliberation, and records are of consistently high quality. Joni Cassidy and her staff have been very responsive to issues brought up by the VBR group, and I hope the flow of information and communication will continue.
