Electronic Collections Online (ECO)
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.

Indexes
Index labels and search examples
Use a colon after an index label (for example, au:) when you are not certain of your search terms. Use an equal sign after an index label (au=) for an exact match search. You can search with an index label from any search screen. The information you type overrides any default menu selections. The following examples show sample rather than actual searches.

Index use and structure
What follows is a list of FirstSearch indexes and the combination of USE and STRUCTURE attributes that can be used to access them.
- For any FirstSearch label where multiple USE attributes are listed all the attributes will provide the exact same search result sets.
- Any USE attribute that is not marked as a restrictor is available via the SCAN service.
- Restrictors are specially implemented indexes and are not available for scanning. Terms for these must be ANDed with other terms to limit the size of the result set. See the table provided for each restrictor to determine valid terms and their associated meaning.

Restrictors
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.
Sorting
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).

Searching tips
Keyword searches (1016):The Keyword search finds information in these fields: Title (245/a), Abstract (520/a), Subject (653/a), and Source (773/t).
Author names searches (1003): Most, but not all, author names are listed last name first. First names or first initials may be listed. Consider using the Unordered Adjacency (n) operator and the Boolean OR operator to search for names.
Publication Date searches (30): Use the Publication Date value (30) to search for articles by publication date. Type dates in this format: YYYYMMDD. You can search for a single date or a range of dates.
Phrase indexes do not include the leading articles A, AN or THE.
