Hmmm.... maybe I am wrong.
This is how I determined page 208 = 192:
Page 8 = Page 24 in the pdf, therefore, Page 192 should be Page (192+16) = 208.

Apologies if this confused you...

3: 978-0-7538-1368-3 8(11)-4- 54(2)-1- 192(7)-1-
9(1)-1- 344(10)-1-   AAaAa

192 (7)-1 should be h. See the pdf file again, page 192 should be the page 208 in the pdf.

If there's no online version of the book, you could use the "look inside" feature of amazon and keep selecting "surprise me" until you get to the right pages.

A paperback (also known as softback or softcover) is a type of book characterized by a thick paper or paperboard cover, and often held together with glue rather than stitches or staples. In contrast, hardcover or hardback books are bound with cardboard covered with cloth; although more expensive, hardbacks are more durable. Inexpensive books bound in paper have existed since at least the 19th century in such forms as pamphlets, yellowbacks, dime novels, and airport novels.[1] Modern paperbacks can be differentiated by size. In the US there are "mass-market paperbacks" and larger "trade paperbacks". In the UK, there are A-format, B-format and the largest C-format sizes.[2]

Paperback editions of books are issued when a publisher decides to release a book in a low-cost format. Cheap paper, glued bindings, and the lack of a hard cover contribute to the inherent low cost of paperbacks. Paperbacks can be the preferred medium when a book is not expected to be a major seller, or in other situations where the publisher wishes to release a book without putting forth a large investment. Examples include many novels, and newer editions or reprintings of older books.

Since hardcovers tend to have a larger profit margin, many publishers try to balance the profit to be made by selling fewer hardcovers against the potential profit to be made by selling more paperbacks with a smaller profit per unit. First editions of many modern books, especially genre fiction, are issued in paperback. Best-selling books, on the other hand, may maintain sales in hardcover for an extended period in order to reap the greater profits that the hardcovers provide.

eISoMm <- I realize the I is not a valid character, but there might be an additional twist

Maybe ROT-13?
qEAbGg

(E) might mean end of the private key
(E) for enigma ??
(E) for encoded / encrypted?
(E) = 5

4 = e. 7= G (Alphabet order) 25 = Y (Alphabet) 1 = o 27 = m 27 = M  
E Equals 5.

or 4, 7 , 27 would be Alphabet order.
first attempt -> eGYoMm5

maybe E is just E
dRNoTtE / eISoMmE

intresting, quite hard to read tho, might be a quote ?

Which country do you live?
anyway i dont have big problem about confirmation time,if that happened to you the solution is fee
