    3838=== Avoid the data type "link" and "id" ===
    39 These fields are database specific and won't return what you think they will.  Selecting id from "Call Number/Volume" will not retrieve call numbers but rather a list of numbers that are used by the db to keep track of call numbers in the system.  It may seem like listing them at all just adds to the complexity of the report generator if they don't return what you might expect, but they're very useful for the db administrator.
