In general, when looking for data, ask yourself who would be interested in this information? A government agency? A nonprofit? A private company? Then try to discover what agencies, companies, or organizations fall under that category, and see if any of them have publicly available data.

Industry codes are a way to help classify industries into categories to group similar firms and companies together. Using an industry code to search will help ensure that you are actually looking at companies that are in similar lines of business.
There are several industry code systems, but the one that is most likely to be useful to you is the North American Industry Classification System, or NAICS.
When searching using an industry code, the more digits you use, the more specific your search will be. We recommend starting your search with only 4-5 of the numbers.

The easiest way to search for materials is by using the Illinois Tech Library Search.
Check out our Library Search User Guide below for more information about performing basic and advanced searches using this tool.
Located in the middle of the library homepage, you can use this search to find known items like required readings and textbooks, or use keywords to find new articles and books.
To look at a particular result, click on the title.
When an item is available online, a list of options will appear under the "View Online" section of the record. Select one of these to access that item. You may be prompted to login with your Illinois Tech credentials before you can view the item.
Use the call number and location listed in the record to find the book on the shelves, or ask at a library help desk for assistance.
Use the link in the catalog, which will automatically populate the request fields, or place a request directly in MyILL using the steps listed on the Interlibrary Loan page of our guide to checking things out.
