The sefarim
Tzofnas Paneach, elucidated
צפנת פענח על הרמב״ם
One continuous project, not a shelf of separate books: a volume-by-volume elucidation of the Rogatchover Gaon's commentary on the Mishneh Torah, following the Rambam's own order.
Each volume sets the Rogatchover's original text alongside three things the reader would otherwise have to supply: the identification of every source he cites without naming, the parallel treatments of the same idea scattered across his other writings and responsa, and the reasoning he left unstated. These are woven into the text rather than printed as a separate commentary alongside it.
The publisher's own description puts it plainly:
המאפשרים ללומד לעמוד על כוונת רבינו שכתב את חידושיו בקיצור נמרץ
The series follows the Rambam's own order. Rabbi Benshimon works from the Rogatchover's handwritten manuscripts, supplied by Machon Tzofnas Paneach. He works alone.

Reception
How the work has been received
“I know some who have a team of people, a whole kollel of avreichim, to put out such a sefer.”
On being presented with the third volume in May 2012 — he already owned the first two. Told that Rabbi Benshimon works alone, he did not hide his surprise, and gave toward the printing of the fourth. Reported here.
“…has brilliantly intertwined the words of the Rogatchover with his annotations and explanations.”
His editor at Mosad HaRav Kook, who described him as a great Torah scholar and said the manuscript needed minimal revision. Reported here.
