If you want scores for analysis, consider getting 'The New Anthology of Music' by Julia Winterson, ISBN 1901507033. It has over 60 works in full score, including cues from 'On the Waterfront', 'Planet of the Apes' and 'ET', as well as classical, vocal, ethnic, jazz and pop. There is also an accompanying multi-CD set which has (almost) every piece.
If you don't have it, I strongly recommend the Adler book and CD combination; there is also a student workbook with lots of listening, orchestrating and comprehension exercises. (Note that, if you want the answers, you have to write to the publishers and convince then you're not actually a music student trying to cheat.)
If you want a handy thesaurus of modern scoring techniques for film, I suggest getting to know the following works, all of which have both multiple recorded versions and easily-available scores:
[list:d396d4b024]The Planets by Holst
Romeo and Juliet by Prokofiev
The Rite of Spring by Stravinsky
Second Symphony by Sibelius
Sixth Symphony by Vaughan Williams
Noctures by Debussy[/list:u:d396d4b024]
Also consider almost any symphonic or film score by Shostakovich, Lieutenant Kije, Alexander Nevsky and Peter and the Wolf by Prokofiev.
If you want printed scores, Dover do decent large-sized reprints that easily tolerate being annotated without obscuring the score. Here are a few I have within arms length, with ISBNs:
[list:d396d4b024]048623861X Tchaikovsky's 4th, 5th and 6th Symphonies
0486260348 Beethoven's 5th, 6th and 7th Symphonies
048624749X Dvorak's 8th and 9th ('From the new world') Symphonies
0486244415 Debussy's Noctures, La Mer and Prelude a l'apres-midi d'un faune
0486247341 Rimsky-Korsakov's Scheherazade[/list:u:d396d4b024]
You can also pick up lots of fairly cheap, good-condition scores by Eulenberg or Boosey & Hawkes on eBay.
If you don't mind printing your own, you can download scads of public-domain scores from the
International Music Score Library Project.
You can also get some scores by Aaron Copland from the
Library of Congress's web site.
