IBM Statement on Inclusive Language in IBM Documentation: While IBM values the use of inclusive language, terms that are outside of IBM’s direct influence, for the sake of maintaining user understanding, are sometimes required. As other industry leaders join IBM in embracing the use of inclusive language, IBM will continue to update the documentation. For more information see IBM Inclusive IT Language
Adobe Indexed PDF Collections
Adobe Indexed PDF Collections contain all the content in a particular release and provide an excellent method for searching for information offline. In addition to containing all the library PDFs, each collection includes an html page that lists all PDFs by title. Each collection, which is packaged as a Windows .zip file, is equipped with an Adobe Acrobat Catalog to provide a full text search mechanism for all content across the collection. To search the content, download the package, unzip the file, then open the included *.pdx file with Adobe Acrobat Reader. (Note that other PDF readers might work but were not tested.) You might need to accept a security warning and then switch to the Search window. Be sure to check out the advanced search options, too.
