|**Return to the BJS home page** |  | Help for using BJS productsBJS provides its products on the Internet in a variety of electronic formats to provide access to users with varying electronic capabilities. 
Some of these formats require interpreting applications you need to install on your computer as plug-ins to web browsers or stand-alone only applications.  The following describes the types of products available that require interpreting applications and provides links to free versions of these applications.

**Acrobat documents**Using the portable document format (.pdf), Acrobat documents 
are full electronic renderings of published documents including the text, page layout and graphics 
that can be viewed and printed on any platform.  A free viewer appropriate for your computer is needed to view an 
Acrobat document. You can download the appropriate viewer and instructions for installation from the **Adobe Systems home page**.  This viewer can be used as a stand-alone or as a plug-in within a web browser to view documents as they are downloaded from the Internet. Instructions on using this software as a plug-in should be available with your web browser.**Spreadsheets**Many tables from our reports and some additional data are available 
in the .wk1 format, readable by most spreadsheet software.  Applications that will read a wk1 file can be used as a helper application with many browsers.  Instructions on using this software as a plug-in should be available with your web browser.  In many instances, the spreadsheets have been grouped and compressed to speed downloads. These archival files are 
presented in .zip format that must be expanded for use.  Freeware to expand such files for most platforms is available from 
**Info-ZIP**, an Internet-based workgroup that provides 
free, portable, high-quality versions of the Zip and Unzip compressor-archiver utilities.  
Commercial expanders for a variety of platforms are also available.
