From the initial (HINARI) PubMed page, we will

The Limits page displays as part of Advanced
Search page. Searches can be limited by
restricting terms to fields or setting specific
date or record tagging parameters. Note that the
Advanced Search option lets you use Limits with
other PubMed features. We will discuss the
Advanced Search options at the end of this module.

This slide notes the Limits options not listed on
the previous one.

Limit by Author(s)
This is an Author name search for Ribeiro. Note
that you can further limit this by using the
first letter of the authors first name.
12
Limit by Author(s)
Here is the Limits Author display for Ribeiro.
Note that there are 6469 citations for this last
name.
13
Note once you have added any Limits, you must
remove the Limits or they will continue to be
active for any other search you complete. There
are two ways to remove Limits. Here we will
click on the Remove hypertext link in the Limits
Activated box.
14
The second ways to remove Limits is by clicking
on the Clear All hypertext link in the middle and
bottom of the Limits page.

The Journal Limits for Natu results in a drop
down menu that lists all the journals with Natu
in the title. We will click on the link to the
Nature biotechnology journal.
16
Limit by Journal(s)
The list ( of articles) for Nature biotechnology
is 6113. It is sorted by Recently Added option.
Remember to clear the Limits or the next search
will retrieve articles only from this journal.
17
This is the Links to full text, Links to free
full text, and Abstracts Limits box. Note, if use
the Links to free full text option, you will
limit the search to only free full text articles
and exclude the HINARI ones. We suggest not
using this Limit although the Abstracts option is
useful.
18
For this example, we will use multiple Limits.
For the HIV AND pregnancy search, we have
selected Practice Guidelines and Review from the
Type of Article option and English from the
Languages option. Note, if your search result
is too large, add more Limits. If the number is
too small, delete some Limits.
19
This Limits search has identified 1608 citations.
To change your Limits, click on the change
hypertext link. Note the Limits Activated
(Practice Guidelines, Review, English) are listed
in a box in the top right of the page.
20
We now will add another Limit All Child 0-18
21
This search has identified 858 citations with the
additional Limit. Again, the Limits Activated
(Practice Guidelines, Review, English, Child
0-18) are noted a box in the top right corner of
the page.
22
We now will Limit the search to 2008 to present
Publication Date. Note that to present is the
default Limit.
23
This search has identified 54 citations with the
additional Limit. Again, the Limits Activated
are noted a box in the top right corner of the
search. Note the listing of the Publication Date
Limits in the Search box.
Remember once you have added any Limits, you
must remove the Limits or they will continue to
be active for any other search you complete.
Here we will click on the Remove hypertext link
in the Limits Activated box.
24
Again, the other way to remove Limits is by
clicking on the Clear All hypertext link in the
middle and bottom of the Limits page.
25
To Limit a term to a specific field in the
record, select an option from the drop down menu
under All Fields. We now will search for WHO in
the Affiliation Limits field. This should now
limit our search to articles where the first
author listed has WHO in the address.
26
For Affiliation, we have added WHO to the Index
box and clicked on AND within the Add to Search
Box with option. Note that the Index option
gives you the listing for WHO and also WHO with
subheadings. We will click on the WHO option to
display the 5033 citations.
27
The whoAffiliation now is displayed in the
PubMed Search box. We will click on the Search
box to complete this query.

• 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 list will be limited to
  only articles that are both free full text and
  HINARI a significantly smaller number.

31
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.
32
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. Note The History option will be reviewed
in Module 4.4
33
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.
34
The results of this Advanced Search are 2038
citations. You can also use the Review/Index,
Details and Citation Search options in Advanced
Search.
This is the end of Module 4.2. There is a
workbook to accompany this part of module. The
workbook will take you through a live session
covering topics included in this demonstration
with working examples.
