Iterations
The new term “iteration” was included to AACR2 2002 rev. in order to reflect a dynamic nature of IR. The iteration is defined by cataloging rules as “an instance of an integrating resource, either as first published, or after it has been updated” (AACR2-2002, Appendix D). IR can be updated on regular or irregular basis. Cataloging rules distinguishes current, later, and first/last iterations of updating Web sites and databases.
The rules for bibliographic description of majority AACR areas (except dates) are based on current iteration of a database. Dates for updating Websites and databases are a problem. Typically, a cataloger would not have the reliable information about the dates of publication/distribution of IR. Because this area is problematic, it was decided to be especially careful with the dates. The main rule states: the dates (260 $c) are based on first or/and last iteration of IR. If a cataloger cannot define if dates given in the resource are the first or last IR iteration, he/she does not allowed to use 260 $c (see p. 22-23 for details). The last two areas of description (7 Note and 8 Standard number and terms of availability) are based on all iterations of IR and any other source, which gives catalogers even more freedom in their decisions.
