Books
There is nothing like a the book format when it comes to readable materials. You can take it with you most everywhere you go. You can underline text and pinch the corner of a page you refer often. You can also get cozy with book, curl up in a chair, lay back in bed or read a few pages while waiting for an appointment.
Books important to genealogy deal with three basic themes, "how to", "hard data", and "related information".
"How to" or "self-help" books are the preferred method of learning for most people. This is especially true if you were not born in the "digital age" and electronic media is just not a comfortable method of learning. There are many good books to help you get started in an orderly way with your personal genealogy. You can find sources for books at your local library or on the internet. You may want to start with a book on genealogy in general, then advance to books focused toward specific needs. For example, there are many books available that are specific to Polish genealogy that address where to look, go, or what to do to get data specific to your Polish ancestors.
Beyond the what to do books, there are books specific to background (related) information such as history, naming conventions, biographies and so on. These add depth to your knowledge on the life and times of your ancestors as well as knowledge that can make your genealogy research more interesting and meaningful.
Magazines: Magazines will not give you "hard data", but they are an excellent source for staying up to date with what's happening or what's new regarding genealogy. They provide featured articles on genealogy, family, history, etc. And, typically, calendar of events, new resources, reviews and more to keep you informed. Subscribing to a monthly magazine is a good idea to stay on top of the latest goings on in genealogy. Plus, like a book, you can read it most anywhere.
