Get to Know Web of Science!
EZ exercise for UAMSers
The Library has exciting news. We now have a campus-wide subscription to Web of Science! In addition to PubMed, this provides a tremendous resource as a second science-heavy database and an invaluable tool for tracking cited references of published works. What exactly does it include?
- Science Citation Index 1945 – Present
- Social Sciences Citation Index 1985 – Present
Web of Science (WOS) provides expansive navigation of citations. You can move backwards in time by clicking Cited References; forward in time via the Times Cited link and expand your search using the Related Records feature.
There are various levels of searches including the General Search which is designed to be easy to use with little training. There is also the Advanced Search mode option where you can build complex search strategies.
Below is a sample record from a general search. Note: This article contained 31 references and has been cited 306 times. Each of these links is searchable.
WOS is available off the library’s database list at: http://www.library.uams.edu/resources/databases.aspx
Remote UAMS faculty, staff and students will have access through our proxy server using your campus domain login.
The Library will be setting up training classes for WOS shortly. Keep an eye on this spot for more Web Of Science news
Getting to Know Web of Science
Things to know in advance:
#1 - Web of Science can be slow in doing some of the more complex functions
#2 - you can access it from home
#3 - there are really great tutorials and educational materials located on the Web of Science main page
You begin with selecting Web of Science from the ‘Databases’ list on the Library’s website (http://www.library.uams.edu). Then go to 'Web of Science'.
ISI Web of Knowledge Opening Page lists resources available to UAMS
This exercise will cover Journal Citation Reports and Web of Science.
(CrossSearch is a quick search using keywords only that goes across multiple databases. You can see what they are under in ‘What databases am I searching?’ You can do a more refined search by adding more search fields.)
Web of Science
Let’s try out Web of Science.
Click on ‘General Search’; this allows for searching by topic, author, source, publication, and address.
Let’s use MD Cave as our example (Dr. Cave has graciously agreed to be our example):
In the ‘Author’ search box, put 'cave md' and click ‘Search’.
We get a list of MD Cave’s publications starting with the most recent articles.
Sort by ‘Times Cited’.
Dr. Cave’s most cited article has been cited 979 times
in the journals covered by Web of Science.
Record #6, an article in JAMA, sounds pretty good to me.
Click on the title. You will see a Full Record with citation information.
Check out ‘Cited References’ to see references used for this article.
Check out ‘ Times Cited’ to see a list of articles that cited this article.
Check out ‘Find Related Records’ to see what articles have cited some of the same references.
Click on ‘Check for UAMS Full Text’ to see if we have the article online. In this case, we do. In the header for this article, you will see ‘Finding Citing Articles’. This lists the 27 articles that Ovid found that cited this article. Not as many as the 112 found by Web of Science. If this were a serious search, you might want to double check this list as well.
On the right side of the page are lots of functions. ‘Create Citation Alert’ sets up an email alert to notify you when another article cites this article. You have to register (for free) to take advantage of this.
You can also look at the Medline record that gives you access to PubMed’s Related Article Summary. In this search it lists 141 related articles.
You can also look at the Journal Citation Reports information on JAMA.
Now we know that Dr. Cave is interested in Mycobacterium tuberculosis.
Click on ‘General Search’ to get back to the search page.
Put Mycobacterium tuberculosis in as a topic and hit ‘search’. For this example take 'cave md' out of the ‘Author’ box. You could leave it in for a search of his articles on mycobacterium tuberculosis, but this time take his name out.
Sort by ‘Times Cited’. You will see what articles on mycobacterium tuberculosis have been cited. There’s Dr. Cave’s article as the 3rd most cited article.
You can analyze the results of this search for mycobacterium tuberculosis by clicking on ‘Analyse’ on the right sidebar. Since these are the most cited mycobacterium tuberculosis articles, you can find out who are the most active authors in this field by analyzing by author. This can be very slow so analyze the first 500 most cited articles and display the first 10. Dr. Cave is not listed in the top ten most prolific authors in the field. Change to top 25 authors. Dr. Cave shows up with 10 out of the 500 most cited articles.
On this same screen, change the ‘Select field to rank by:’ to Institution Name. If you are looking through the first 500 records and show the top 25, you’ll find UAMS in the list. Looking for articles with a UAMS author is interesting, too.
To check on authors at UAMS, go back to the ‘General Search’ page.
Take ‘mycobacterium tuberculosis’ out of the Topic box.
Put ‘univ Arkansas med sci’ into the Address box. You should use this specific abbreviation. You can see the most recent articles published by UAMS authors. It is close to being in order chronologically with the latest article at the top. However, there are minor variations because it depends on when the article was indexed – not just when it was published. WOS has fast indexing so there won’t be too much variance. This search may also vary if you alter the abbreviation of the institution name. For example - 'Univ Arkansas Med Sci Hosp' and 'UAMS' will bring in different results. This variation comes from different authors using varying names for the same institution.
Now sort by ‘Times Cited’ to see the most cited articles by UAMS authors.
Well, this is probably all the time either of us has for now. There is so much in this resource that you can explore. So, feel free to explore and share with others.
Also, please remember, Web of Science searches over 8400 journals and yet there are still other tools to use to be complete. No tool covers everything, but we believe Web of Science does best.
Check out PubMed’s related articles and Google Scholar as well.
Journal Citation Reports
Now let’s look at Journal Citation Reports.
2004 is the latest year available at this time.
Click on ‘Information for New Users’ if you aren’t familiar with JCR.
Go back and select ‘View a group of journals by Subject Category’.
Select a category you are interested in. I chose ‘neurosciences’. You can select more than one category if you wish. Here you can also select how you want the information sorted. You can also resort them later on the next webpage.
The Journal Summary List page is packed with interesting information. You can sort by ‘Impact Factor’ and various ways. Click on a journal title and you can learn how the various columns are calculated. This is the same information you would see if you had selected ‘Search for a specific title’ on the JCR opening page. You can check out all 5,969 journals in JCR as well. Click on ‘Home’ to return to Web of Knowledge webpage.
