WEBTech Notes

This resource is a database of class changes and updates to the List of Classes. It is is designed to support the management of Federal depository library collections.Federal depository libraries use WEBTech Notes to search, browse, and view updates to Superintendent of Documents classification numbers (SuDocs) and to List of Classes information, but it is a useful tool for all catalogers. WebTech Notes may be used to learn more about the history of an item number.

Depository Item Profile: Item Selection & Deselection

Depository Selection Information Management System (DSIMS) is the place to go to add or drop item numbers from your selection profile. Read about Depository Selection Information Management System (DSIMS) before trying to use the system. Depository libraries may drop items from their profiles at any time using DSIMS, and EL-only items may be added at any time. Tangible format items may be added throughout the year but selections will become effective with the new fiscal year that begins on October 1. Libraries may wish to use DDM2 to determine which new EL items may have been added before amending their item selection profile.
