During my daily commute I listened to academicmp3audiobooks.com lecture. Great overview of English Literature is "Introduction to English Literature." Get the longer (12 hour) version.
Masterplots was a "must have" for me. A full multi-volume set can be expensive. I located a cheap 1963 version on e-Bay. The short plot summaries and character lists were very helpful. Most would recommend reading Masterplots at the library. I paid about $25 for my 15 volume set from e-Bay, including shipping.
I have a variety of Nortons Anthologies--Classical, Middle Ages, American, two volumes of English.
For excerpts of older stuff there is Project Gutenberg. Reading passages of full text novels helped me get the feel for an author's style. Electronic Text Center at the University of Virginia Library is also a great resource.
The three ETS practice tests, "Cracking the GRE" and old REA book with six tests.
The Complete Idiot's Guide to American Literature was an easy read.
On the back shelf, behind the more useful books were...Bullfinch's Myths, and Jack Rudman's book, and a bunch of ETS material that duplicates infomation in other versions. Thanks God for e-bay and half.com. No way I could've accumulated half the books (Masterplots aside) at retail.
A few general purpose resources I found helpful:
The "Way Back Machine" at Archive.org is great for following broken links for information that has moved or is not longer posted.
Wikipedia, "the free encyclopedia that anyone can edit."
Quiz Buddy from www.quizbuddy.com was a handy tool. One technique I used for absorbing information was loading terms into a quizing program. I used Quiz Buddy because it has an application for my Palm Pilot. It was great for learning timeline related material such as the dates for reigning monarchs. Quiz Buddy was *not* the easiest application to learn, but I found it very useful. Great way to run pop quizes throughout the day.
Online quizes include
The Tongue Untied, A Guide to Grammar Punctuation and Style.
Especially helpful was the Interactive Verb Quiz 1.
Also watching some DVD versions of Shakespeare. Probably a waste of time for sole purpose of GRE Lit, but won't hurt. May help. It beats staring at a blank tv screen, which is about what I'm ready for at the end of the day.
Which Norton Anthologies are most helpful?
I found the these four volumes of Nortons essential:
English Literature as two volumes
American Literature as two volumes
I also opted for Middle Ages and Classical volumes because 1) I wanted to go more in-depth 2) I was interested in the subjects and 3) because I found cheap used copies, mostly at half.com.
I did not read them cover to cover. I did read most of the overview of time periods and schools of writers. I also read samples from major authors. If an author was mentioned in Princeton Review or some of the websites I've come across I would use the Norton's to help identify the author's work.
