Time-Life recipes appear in a number of Time-Life cookbooks published between the 1970s and the 1990s. Many of these cookbooks are out of print as of 2015, but they are still available used at thrift stores, used book stores, or websites such as eBay.
There are also a number of used book sites online, such as AbeBooks, that allow users to search for used copies of out-of-print books. Amazon.com is another resource for finding out-of-print books. Depending on the area, a local library may have a copy of the Time-Life cookbooks, or it may be able to get them through the interlibrary loan system.
