Search property data in 2,000 e-books

Knovel has launched the first of several database enhancements, making it easier and faster to find reliable technical information. Changes include:

  • Graphs/Equations/Tables (G.E.T.) search tab
  • Improved search results display
  • Keyword auto-complete
  • Spell check
  • Suggested search terms
Graphs, Equations & Tables search

You can search for numeric and other tabular data contained in Knovel's interactive graphs, equations and tables from over 2,000 books and databases. Data can be sorted, filtered, and extracted to other formats, such as Excel and HTML. Types of data you can search:
