What is the Astronomy Book Club? 
Astronomy Book Club is a very special club — 
one that is operated exclusively for astronomy en- 
thusiasts. The Club is devoted to making the finest 
astronomy books available conveniently and inex- 
pensively! 
4 Good Reasons to Join 
1. The Finest Books. Of the hundreds and hundreds of 
books submitted to us each year, only the very finest are 
selected and offered. Moreover, our books are always of 
equal quality to publishers’ editions, never economy edi- 
tions. 
2. Big Savings. In addition to getting the BASIC AS- 
TRONOMY LIBRARY for only $2.95 when you join, you 
keep saving substantially — up to 30 r o and occasionally 
even more. (For example, your total savings as a trial mem- 
ber — including this introductory offer — can easily be over 
50 lr o. That’s like getting every other book free!) 
3. Bonus Books. Also, you will immediately become eligi- 
ble to participate in our Bonus Book Plan, with savings of 
at least 70 r o off the publisher’s price on any book offered in 
the Club. 
4. Convenient Service. At 3-4 week intervals ( 16 times per 
year) you will receive the Book Club News, describing the 
Main Selection and Alternate Selections, together with a 
dated reply card. If you want the Main Selection, do noth- 
ing and it will be sent to you automatically. If you prefer 
another selection, or no book at all, simply indicate your 
choice on the card, and return it by the date specified. You 
will have at least 10 days to decide. If, because of late mail 
delivery of the News, you should receive a book you do not 
want, we guarantee return postage.
