## Indexing

- FY2006
- 629,000 indexed citations added to MEDLINE.
- Highest ever indexing rate (last year was 606,596 indexed citations).
- 46,918 gene indexing links created (4% increase from last year).
- FY2007
- 175,177 citations indexed in during the 2nd quarter, at a rate of over 700,000 articles per year.
- More than 85% of MEDLINE citations now supplied electronically by publishers.

## Indexing

- New Web-based training program for MEDLINE indexing is the primary instruction method for new indexers.
- A version for end-user access to be provided by early summer.

## Indexing

- Electronic Journal Indexing
- 120 online-only journals indexed for MEDLINE, an increase from 107 a year ago.
- 276 additional journals - the online version is indexed instead of the print version.

## Indexing

- Kennedy Institute of Ethics (KIE) - Bioethics data:
- NLM supplies over 85% of the bioethics citations creation and indexing.
- Contract reduction due to budgetary constraints.
- NLM continues to provide funding to support the National Reference Center for Bioethics Literature at KIE; it offers search systems and other services for bioethics literature and their own collection.

## Bioethics Information Resources

- Web resource developed to provide additional support to the subject of bioethics.
-  _[www.nlm.nih.gov/bsd/bioethics.html](http://www.nlm.nih.gov/bsd/bioethics.html)_
- Main links on:
- PubMed Special Queries page.
- List of NLM Databases and Resources on the NLM Home page.

## Slide 8

- 40,640 new abstracts added from 23 titles.
- 15 titles did not have new abstracts to add.
- Process now part of standard workflow for PMC scanned citations to be included in MEDLINE/PubMed.

## 3rd Party Back Issue Citations
