APM Index is an index of the 973 Alvarez Group Memos, dated 4/4/58 through 9/1/90 (although there are only four memos past 1986. Almost 75 memos that are missing from those files are so marked in this Index.

A number of memos (especially those that gave instructions for scanning bubble-chamber film or that described data-analysis programs) were revised. When a revised memo is in the file, it is its title, date, and author(s) that is given below; these are often evident because there dates are later than those of neighboring memos. A number of memos have attachments, sometimes by other authors. No account of these has been taken in this Index — there are limits.

Abbreviations such as B.C. (bubble chamber) in the actual titles have been spelled out. Greek symbols have replaced anglicized Greek. Program names are in slant. Hyphens, semicolons, "the"s, etc., have been liberally inserted to make the titles more readable.

The memos themselves are available as pdf files at APM Memos. Rather than store all of the memos in individual files, they have been grouped ten to a file. We call these Decade files. Thus if you decide you would like to see Memo 715, Multiple Scattering of Monopoles by Philippe Eberhard, you can enter the Memo Number 715 in the box provided. What will be retrieved for you is the file containing memos 711 through 720, and you will see Memo 711 by Stan Flatté on the screen. Scan down until you come to 715. The memos are separated by a blank page between them.

The page images of the memo may be selected, copied, and pasted into any file which will accept images, such as MS Word, from which they can be saved with the Save As command.
