Welcome to the PubMed Homepage. Part 2 of the
tutorial will look at using the Limits function
to narrow down our search results by different
parameters. If we type in a search statement such
as tuberculosis in the Search box, we will get a
large number of records in our results.

The tuberculosis search will return almost 173000
hits. This is too many to view in any meaningful
way. This includes almost 22000 HINARI
citations and 19000 Free full text citations

• Reminder While working with LIMITS, you
  probably noticed the line that has Links to full
  text, Links to free full text and Abstracts
  options. By clicking on all three options, you
  would limit your search to all full text articles
  AND those articles that are available as free
  full text by various publishers AND those that
  have abstracts.
• Consequently, your HINARI tab will be limited to
  only articles that are both free full text and
  HINARI a significantly smaller number.

38
Limits page 1
We now will use new Advanced Search option that
enables you to use Limits with other PubMed
features. Note that you can access Advanced
Search from Limits, History or the other PubMed
options listed above.

We have activated the Advanced Search option that
displays the Most Recent Queries History. In this
exercise, we will use Search 3 a combination
of the tuberculosis AND Africa and HIV AND Africa
searches. By using Limits, we will refine this
search.
40
For search 3, we have added the English
Languages and Practice Guidelines and Review Type
of Article and the All Child 0-18 years Ages
Limits.

The results of this Advanced Search are 57
citations with 5 Free full text and 27 HINARI
accessible citations. In the beige box, the
Limits applied are listed. You also can use the
Preview/Index, Details and Citation Search
options in Advanced Search.
This is the end of Module 4 Part 2. There is a
