ASERL Center of Excellence (COE) Database: I've identified a gap, now what?

Instructions for using the ASERL Center of Excellence (COE) Database


Title 44, Section 1912, of the U.S. Code states that Regional depository libraries may permit Selective depository libraries to dispose of Government publications which they have retained for five years after first offering them to other depository libraries within their area, then to other libraries. The Association of Southeast Research Libraries (ASERL) has developed an online Documents Disposition Database that streamlines the process, thus reducing staff time for all libraries involved in the disposition process.

 The ASERL Disposition database accommodates the posting of both needs and offers lists and may be accessed through the following link -

 For more information on the ASERL Disposition database, please see the UF Libraries LibGuide.

 COE library commits to creating a complete as possible collection including the filling of gaps in the COE collection.  Gaps are identified during the compilation of the comprehensive list or by running the gap analysis in the ASERL COE database.  There are several options for filling gaps in collection including:

  • obtaining physical copies or digital surrogates from other participating libraries
  • obtaining physical items offered through the ASERL disposition database
  • obtaining items offered from GPO’s Needs & Offers lists; or
  • obtaining items offered by individual libraries on GOVDOC-L and other discussion lists
