New Features

• The Country search feature is now called Country/Territory (or Countries/Territories where appropriate).
  
  
• From the Rankings page for Scientist, Institution, Journal, or Country/Territory, you can now display items that have a specific number of citations, papers, or citations per paper. The default value is zero, but you can change this value to 5, 10, 15, and so on.
  
  
• New search fields have been added to the Hot Papers and Highly Cited Papers menus. You can now search by Scientist, Institution, Journal, Country/Territory, and Title word.
  
  
• The AND Boolean operator works in Title word searches (Hot Papers and Highly Cited Papers) and Topic word searches (Research Fronts). The OR Boolean operator works in Topic word searches.
  
  
• The Percentiles page now displays a 20.00% row and a 50.00% row, in addition to the 0.01%, 0.10%, 1.00%, and 10.00% rows.
  
  
• A third page of statistics (By Field Rankings) was added to the Baselines Menu. This page (Field Rankings table) lists the 22 fields and gives the total citations, papers, and citations per paper for each field.
  
  
• You can now view statistical information in graphic format or table format for Top Papers for Scientists, Institutions, Journals, and Countries/Territories.
  
  
• You can now view the Hot Papers Graph in table format. It also shows the number of citations (by bi-monthly period) for a particular field.
  
  
• A new Hot Papers graph is available from the Hot Papers page that shows the Number of Citations (by year) for a selected paper. You can also view this data in table format.
  
  
• The color of the graph bars on the graph pages have been changed from red to gray.



• When viewing the Field Rankings for a particular scientist, institution, country/territory, or journal, clicking on the field name (or All Fields) takes you to the Scientist, Institution, Country/Territory, or Journal Rankings page of that field (or All Fields).
  
  
• An All Fields row of statistics appears on the Field Rankings page (last row in list) for an individual scientist, institution, country/territory, or journal giving the All Fields totals (citations, papers, and citations per paper) for that item.
  
  
• A Research Front button now appears on a specific Papers page indicating that the paper is in a Research Front. Click the button to go to a Rankings page for that Research Front.
  
  
• A Commentary button now appears on a specific Papers page indicating that the paper has an Editorial Comment in in-cites or Special Topics. Click the button to open a new window to the editorial item.
  
  
• A Hot Paper button now appears on a specific Papers page indicating that the paper is a Hot Paper. Click the button to go to the Hot Papers page to access its Bimonthly Citation graph.
  
  
• The name of the field (e.g., Chemistry) to which an individual paper is assigned appears on the Papers page in the Field column. This field name is linked to the specific ranking of that paper in its Field Ranking.

System-Related Issues

Hyperlinks from the Papers List

The hyperlinks that appear on Papers pages (e.g., Hot Papers, Top Papers, Core Papers, and Highly Cited Papers) allow users to link directly to rankings for the scientists, institutions, countries/territories, and journals. Please note, however, that when entries are not linked it does not necessarily mean that there is no associated ranking. Rankings are best determined from the Rankings Menus.

Using Special Characters, Punctuation, and Stopwords

When a search query includes special characters, punctuation, or a stopword it may return no results or incomplete results. Try the same search excluding the special characters or stopwords. A complete list of stopwords can be accessed from the Index of the Help system.

Viewing Single Paper Graphs

When viewing single paper graphs and multipaper graphs, please keep in mind that the bar representing the current year will be affected by the number of bimonthly updates processed to date. Earlier in the year, the trend may appear to slow down, while close to the end of the year the trend displayed in the graph may appear to normalize according to the past citation rates of the selected item or items.
