In 2011, OCLC discontinued updates to the Electronic Collections Online (ECO) database and moved database content to a service archive. ECO metadata through the 2011 end of updates is still searchable as a database on the FirstSearch service. In addition, libraries that maintain an annual access fee can continue to link to articles in journals from their previous Electronic Collections Online subscriptions as long as OCLC still has access to this content.
Since no changes have been made to ECO metadata or article content since 2011, and OCLC has no plans to reinstitute updates, ECO metadata and article content are not included in FirstSearch COUNTER 5 reports.

The following restrictors can be used only in conjunction with an index search. They must be added to an index search with the Boolean AND to receive search results:
| Restrictors | Type | Use Attribute | Structure Attribute | Notes |
|---|---|---|---|---|
| Year* | All (--) Single (1999) Range (1992-1998) |
31 | 5 | Restrict to a single year, or a range of years. |
* Year is both an index and a restrictor.
Search results in the Electronic Collections Online database of article records can be sorted by Author (1003), Title (4), and Publication Date (30). Search results of journal records can be sorted by Title (5246).
