• Introduction includes: Flags, seals, coats of arms.
• Biographical Dictionary contains: Names of 10,000 noteworthy persons, and includes their nationality, profession, and birth and death dates. (Printed in 1913)
• Signs and Illustrations includes: "Classified Selection of Pictorial Illustrations" (with index at bottom of 5th page), which includes topics such as anatomy, architecture, botany, musical instruments, vehicles, a large zoology section, and much more.

• Heidi (34) in RC is split into 2 volumes, but if you buy it somewhere you'll most likely get the entire thing in one book.
  
  
• Alice's Adventures in Wonderland (40) and Through the Looking-Glass are actually 2 separate books. If you buy them, be sure to get both. Some versions combine the two into one volume, while some versions leave them as separate books.
  
  
• Gulliver's Travels (65) was not originally written for children, and you may prefer the Children's Version from 1900, found online. It has parts 3 and 4 deleted (the parts about sorcerers, necromancy, and raising people from the dead), and also has the crude and inappropriate parts removed from the rest of the book. Here's a bit more about what's objectionable about this book.
  
  
• The Life of George Washington (72, 77, 80) by Irving was a 5-volume set. RC contains 3 of the 5. (Irving originally thought it would fit into 3. It was published as 3 at first, but was incomplete and later published as the completed 5 volumes.) You can read the incomplete RC set, or get the last 2 volumes free online. Or there also a free condensed version of Irving's volumes, which is still over 700 pages long.
  
  
• RC's Robinson Crusoe (75) contains "The Adventures of Robinson Crusoe" and "The Further Adventures of Robinson Crusoe," which are sometimes found separately.
  
  
• Pudd'nhead Wilson and Those Extraordinary Twins (88) are two different books. If purchasing, you may or may not be able to find them bound together in a single volume, so just make sure to get both.
  
  
• Economic Sophisms (96) is translated from the original French. It's usually found under this title, but because of minor differences in translations you may find it in stores (or online) under a different name. Other titles you may find it under are: Sophisms of the Protectionists, Sophisms of Protection, Sophisms of the Protective Policy, Sophismes Economiques, or Economic Fallacies.
           The RC version contains Series 1 and Series 2.
  
  
• The Mysterious Island (109) is the sequel to "Twenty Thousand Leagues Under the Sea." Find out what happened to Captain Nemo!

• Don Quixote (115). This book was originally published in two parts, in 1605 and 1615. The RC book (same as The Harvard Classics Vol. 14) is just part one, but if you're buying the book or getting it free online, you may prefer getting both parts. If buying, it may vary from one version to another whether or not it contains both parts. Funny note: Someone else (under the name of Avellaneda) wrote an unauthorized Part 2 in 1614. Cervantes makes mention of this "False Quixote" in his own Part 2, weaving it into his story in a rather humorous way. (I've linked to a free version with Parts 1 & 2 by Cervantes.)
  
  
• Memoirs of Gen. W. T. Sherman (118). The RC book contains both Volumes 1 and 2. It's not indicated in a table of contents because it is 2 books put into one file. Volume 2 begins on page 432 in the RC software. (After page 433 on the printed page of Volume 1.) If buying or downloading, be sure to get both volumes.
  
  
• What RC calls On the Motion of the Heart and Blood in Animals (125) is actually a collection of 7 separate scientific papers, by various authors, taken from The Harvard Classics Vol. 38; Scientific Papers. Here are their titles:
  
  - On the Motion of the Heart and Blood in Animals - William Harvey
  - The Three Original Publications on Vaccination Against Smallpox - Edward Jenner
  - The Contagiousness of Puerperal Fever - Oliver Wendell Holmes
  - On the Antiseptic Principle of the Practice of Surgery - Joseph Lister
  - The Physiological Theory of Fermentation - Louis Pasteur
  - The Germ Theory and its Applications to Medicine and Surgery - Louis Pasteur
  - On the Extension of the Germ Theory to the Etiology of Certain Common Diseases - Louis Pasteur
  
  
• American Historical Documents 1000-1904 (126) is almost 500 pages of important historical documents and historical accounts. Wow! (It's also The Harvard Classics Vol. 43)
  
  
• RC's A Constitutional View of the Late War Between the States (129) contains both Volumes 1 and 2. It's not indicated in a table of contents because it is 2 books put into one file. Volume 2 begins on page 662 in the RC software. (After page 654 on the printed page of Volume 1.) If buying or downloading, be sure to get both volumes.
  
  
• What RC calls Faraday's Lectures (134) is actually 2 different books (lectures) titled: "The Forces of Matter" and "The Chemical History of a Candle." (Taken from The Harvard Classics Vol. 30.) If buying or downloading, be sure to get both titles.
  
  
• The World Crisis (138) contained in RC is only Volume 1 of Churchill's multi-volume work about WWI. The RC book covers up to 1915, though the war went through 1918. Amazon has complete sets available, but they're quite expensive. For an inexpensive book about the whole war, you could get the complete single-volume version (or here), which is Churchill's abridgement.
  
  
• Paradise Lost (144) in RC also contains some notes about the book, and an 89 page biography of Milton, called "Life of the Author" by John Mitford.
  
  
• (An Inquiry into the Nature and Causes of) The Wealth of Nations (145) is sometimes broken up into different volumes, but RC contains all of them. If purchasing, you'll most likely find a complete version bound into a single book.
  
  
• The Ultimate Resource 2 (151) is not a sequel or second volume, but an updated version of the book.
  
  
• Access to Energy (152) is not a book, but a series of "pro-science, pro-technology, pro-free enterprise" newsletters published by Art Robinson. RC contains 39 newsletters in all, spanning from Vol. 21, no. 1 (Sept. 1993) through Vol. 24, No. 3 (Nov. 1996). They can be found in a free archive online (linked here) rather than in a book store.
  
  
• Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (155) is in 2 parts in the RC book. If buying, both will most likely be bound together in a single book.
  
  
• De Bello Gallico or Bellum Gallicum or C. Iuli Caesaris Commentarii (157) appears to be the commentary of a modern author (T. Rice Holmes) about Caesar's commentary on the Gallic War. The text is the same as book #136, only it is in Latin, and contains the editor's commentary. His commentary is an explanation of Caesar's text. At least that's what I've gathered from it, but I could be wrong. If you've read it, I'd like to hear your input on this book.

Here are the errors to fix in RC, if using book #503:
  9 x 12 =   8   should say     9 x 12 = 108
10 x 10 =   0   should say   10 x 10 = 100
10 x 11 = 10   should say   10 x 11 = 110
10 x 12 = 20   should say   10 x 12 = 120
11 x 10 = 10   should say   11 x 10 = 110
11 x 11 = 21   should say   11 x 11 = 121
11 x 12 = 32   should say   11 x 12 = 132
12 x   9 =   8   should say   12 x   9 = 108
12 x 10 = 20   should say   12 x 10 = 120
12 x 11 = 32   should say   12 x 11 = 132
12 x 12 = 44   should say   12 x 12 = 144
90 / 10 = 90   should say     90 / 10 =   9
12 / 11 = 11   should say   121 / 11 = 11
14 / 12 = 12   should say   144 / 12 = 12

• Going through the words with a parent the first time seems to be helpful. (At least when they are younger.) When we start a new batch of vocabulary, I ask my daughter if she knows what the word means before I even tell her. (Sometimes she already does!) I can explain the word in term she understands, and use it in a sentence for her. (Not the one from the card.)
  
  
• At our house, it is only required to memorize the definition. Often the word on the card doesn't fit properly into the sentence anyway (like the vocab word doesn't end in "ing", but it would in the sentence), which only confuses kids. Try skipping the sentences (printing the cards without it is an option), or fix the sentence so it's right. (Like writing "ing" in there.)
  
  
• It's possible to learn the definition, and sentence, and still not understand the meaning of the word. When my daughter feels she knows the definitions well enough, we go through them together. She gives me the cards and tells me the definition, and then I have her tell me a sentence of her own. This is the true test! Then I know if my daughter's just memorized the words on the card, or if they've sunk in.
  
  
• They don't need to memorize verbatim to really understand the word. Don't be too big of a stickler. Remember that the point is for the child to understand the meaning, however it is phrased.
  
  
• There are words in the vocabulary that the child may already know. In this case, we put it in the done pile. I don't make my daughter memorize a sentence and word-for-word definition if she already understands the meaning. She already knows it. It's done.
  
  
• It's okay to change the definitions! - (As long as they're accurate, of course!) Feel free to cross out and write in better definitions. Some of the cards offer nothing more than a list of difficult synonyms, rather than a real definition. Learning synonyms is great, but they don't make good definitions on their own.
           There's nothing "dumbed down" about giving children a resource they can actually learn from. If they can't understand the definition given, we're just wasting their time. The entire goal is for the child to understand the meaning of the word. It doesn't matter if you get a simple definition from a kid's dictionary, or one from Webster's unabridged, as long as it's correct.
           Something to think about --
  The definition of the word "definition" is: "the act of defining or making definite, distinct, or clear."
  
  There's a great online dictionary we've been using at Wordsmyth.Net. You can get regular definitions, or simpler ones for children. Using an online dictionary saves lots of time when you have many words to look up.

• Instead of printing the vocabulary flashcards, you could just print the Vocabulary List from the Vocabulary Exercises book. Students can learn from the list just the same way we did when we were in school. (Cover definitions with hand / paper while going through list repeatedly.)
  
  
• If you want a vocabulary quiz you could use the vocabulary Matching Game from the RC vocabulary exercises book.
  Or try this RC Vocabulary Quiz Index which has a quizzes and solutions for all the RC vocabulary words. (Archived page.)

• You could make a list of the RC words for each book, look them up and write down the definitions (or have older kids do that part themselves). Then use that list of definitions to memorize from. Try the online dictionary at Wordsmyth.Net. You can get regular definitions, or simpler ones for children.
  
  
• After doing the option above (looking up better definitions for the RC words), if you still have motivation / time, make them into flashcards with the free CueCard program.

• Build vocabulary through reading
  Have students write down words they don't understand as they read. Then choose one of the following to do with that list:
  
  
  • Look them up at the end of their reading time. (Or they could look them up as they read, if they prefer that way, and don't worry about writing them down.) The theory here being that if they come across a word often enough, and look it up if they don't remember, that eventually they will remember the definition.
    
    
  • Look up and write down the definitions, so they make more of an impression. Goes along with the theory mentioned just above. (That if they come across a word often enough it must be important, and they'll look it up until they remember it.)
    
    
  • Look up and write down the definitions. Then at the end of the week (or some time frame), that becomes the list of words to memorize during the next week. (A parent can look over the list and decide whether to use the whole thing, or to only select certain words for memorization.)
  
  
  
• Use an SAT vocabulary list from Sesame Words or one of the sites listed at the bottom.
           3 lists of varying sizes available, created from a 2007 SAT test. The words are divided up into lessons. This could be a useful feature if you want to divide up the lists through your child's homeschooling years. The high frequency list appears to contain easier words, and the low frequency list contains more difficult words. (Not in all cases, but it makes sense that harder words would generally be used less frequently on the SAT).
           Available Lists: Top Frequency SAT (450 Words); Mid Frequency SAT (1350 Words); Low Frequency SAT (2700 Words)
  
           Ways to use the list of your choice:
  
  • If your list isn't already broken into lessons, you can break it up into smaller chunks to learn a bit at a time. You may want to mix up each section a bit (alphabetically, that is) so you don't confuse your child by handing them a list of all "a" or all "b" words to memorize at one time.
    
    
  • Go one step further from the last idea, and use the list to make flashcards with a free program like CueCard.
    
    
  • Use it for SAT prep with older students (that's what is was made for, after all) and don't worry about using any specific vocabulary program before that. (Or maybe combine this with another method mentioned above in "build vocabulary through reading", for years prior to SAT prep.
